Device 1, shown schematically, comprises an imaging device 2 and a first and second holding device 3a, 3b. In this preferred embodiment, imaging device 2 comprises a single imaging arrangement 20. This imaging arrangement 20 has a beam passage plane SE, in relation to which an optical axis O is arranged with a substantially orthogonal orientation. The first and second holding devices 3a, 3b each have a first and second holding plane Ha, Hb, which are oriented substantially parallel with beam passage plane SE. In particular, the first holding device 3a having the first holding plane Ha is spaced apart at a first distance A1 from beam passage plane SE. The second holding device 3b having the second holding plane Hb is spaced apart at a second distance A2 from the first holding plane Ha.

    [0130] FIG. 1 shows device 1 in the operating condition. In the operating condition, a photoactive arrangement 11 of the photoactive system to be produced 10 and an optical arrangement 12 of the photoactive system 10 are already arranged in the respective holding device 3a, 3b. Optical arrangement 12 is arranged at infinity in relation to imaging device 2 and images photoactive arrangement 11 at infinity. In an upstream step, in the logistics condition of device 1, photoactive arrangement 11 and optical arrangement 12 were added to the respective holding device 3a, 3b. In order to produce a deactivated photoactive system, in particular, optical arrangement 12 and the photoactive arrangement are not contacted in the operating condition with one or more electronic contacts for power supply and/or data transmission. In the preferred embodiment shown schematically in FIG. 1, optical arrangement 12 is arranged in the first holding device 3a and photoactive arrangement 11 is arranged in the second holding device 3b. Both the first and the second holding device 3a, 3b are designed to hold optical arrangement 12 and/or photoactive arrangement 11. In the operating condition, optical arrangement 12 and/or photoactive arrangement 11 are arranged and accommodated force-fittingly and/or form-fittingly in the respective holding device 3a, 3b. The respective holding device comprises, for example, a clamp jaw gripper and/or a vacuum gripper for holding optical arrangement 12 and photoactive arrangement 11 in the respective holding device 3a, 3b.

    [0131] The imaging arrangement 20 of device 1 shown schematically in FIG. 1 has an imaging module 21 which is arranged substantially on beam passage plane SE and concentrically with optical axis O. In this preferred embodiment, imaging module 21 is a converging lens. In the preferred embodiment shown in FIG. 1, imaging module 21 is designed to image electromagnetic beams at infinity along optical axis O in a direction of the first and second holding planes Ha, Hb. In a direction opposite thereto, away from the first and second holding plane Ha, Hb, imaging module 21 is designed to image electromagnetic beams at finity along optical axis O on a first focal plane B1 of imaging module 21.

    [0132] In the present embodiment, optical arrangement 12 of the photoactive system 10 to be produced is a converging lens, and photoactive arrangement 11 of the photoactive system 10 to be produced 10 is an image sensor arranged on a support. The first and second holding devices 3a, 3b are designed in such a way, in particular, that the converging lens 11 arranged in the respective holding devices 3a, 3b in the operating condition and image sensor 12 are arranged and held substantially in the respective holding plane Ha, Hb. In particular, the converging lens is designed to focus the electromagnetic beams emanating from imaging arrangement 20 on a third focal plane B3 in the direction of the second holding plane Hb. In particular, the image sensor of photoactive arrangement 11 is arranged and oriented on the second holding plane Hb. In order to produce the photoactive system in the operating condition, the first holding device 3a having converging lens 12 arranged therein and the second holding device 3b having photoactive arrangement 12 arranged therein are preferably oriented in relation to each other in such a way that the second distance A2 is substantially equal to the focal length of the converging lens 12 of the photoactive system 10 to be produced, i.e. the third focal plane B3 of converging lens 12 in the image sensor of photoactive arrangement 11 lies on the second holding plane Hb.

    [0133] The imaging arrangement 20 shown schematically in FIG. 1 is designed to generate electromagnetic beams. The electromagnetic beams leave imaging arrangement 20 through the imaging module 21 arranged in beam passage plane SE. The imaging module 21 of imaging arrangement 20 is designed to image the electromagnetic beams at infinity. Imaging arrangement 20 is also designed to focus the electromagnetic beams reflected by the image sensor of photoactive arrangement 11 and focused at infinity in the direction of beam passage plane SE by converging lens 12, in order to focus an evaluation image on a first focal plane B1 by means of imaging module 21 and to capture the evaluation image. Depending on an imaging quality of the captured evaluation image, the first holding device 3a with converging lens 12 is adjusted in the operating condition with regard to its orientation and position in relation to the second holding device 3b having the image sensor of photoactive arrangement 11 disposed therein.

    [0134] In order to adjust it, the first holding device 3a of device 1 shown schematically in FIG. 1 is movably positioned relative to imaging device 2 and the second holding device 3b, and imaging device 2 and the second holding device 3b are stationarily positioned. In particular, the first holding device 3a is translationally movable along optical axis O and rotationally movable about optical axis O. The first holding device 3a is also translationally movable along and rotationally movable about two other axes (not shown). Optical axis O and the two other axes are orthogonal to each other. The orientation and/or position of the converging lens relative to the image sensor can be adjusted by moving the first holding device 3a translationally along one of the three axes and/or by rotationally moving it about one of the three axes. If a desired imaging quality is achieved in an orientation and/or position of the photoactive arrangement 11 relative to optical arrangement 12, device 1 is designed to hold the first holding device 3a stationary in its orientation and/or position relative to the second holding device 3b for assembly purposes, i.e. for connecting optical arrangement 12 to photoactive arrangement 11.

    [0135] FIGS. 1a-1f show preferred embodiments of the device. The preferred embodiments of the device shown in FIGS. 1a-1f are based on the embodiment of the device shown in FIG. 1. Unlike the embodiment shown in FIG. 1, the embodiments shown in FIGS. 1a-1f have two first holding devices 3a and two second holding devices 3b. The devices shown in FIGS. 1a-1f are designed to produce two photoactive systems.

    [0136] The device 1 shown in FIG. 1a has a movable imaging device 2. Imaging device 2 is movable substantially parallel with the first and/or second holding plane Ha, Hb of the first and/or second holding device 3a, 3b. The photoactive system 10 shown on the left in FIG. 1a is firstly produced. Once the photoactive system on the left has been produced, imaging device 2 is moved to the right from a position on the left (continuous line) into a right-hand position (broken line) in order to produce the second photoactive system 10 relative to the first photoactive system already produced, shown on the left in FIG. 1a. To that end, an image stored by the photoactive system 10 already produced is virtually superimposed by an image of the photoactive system 10 still to be produced and, depending thereon, the photoactive system still to be produced is adjusted via the first and/or second holding device 3a, 3b.

    [0137] The imaging device 2 shown in FIG. 1a, in particular the at least one imaging arrangement 20 of imaging device 2, can be orbitally pivoted relative to the photoactive system 10 to be produced. In the right-hand position (dotted line) in FIG. 1a, a pivoted imaging arrangement 20 is shown schematically.

    [0138] The device 1 shown in FIG. 1b is so designed that two photoactive systems to be produced can be simultaneously captured by means of the imaging device. The imaging arrangement 20 of imaging device 2 is movable, in particular pivotable. FIG. 1b schematically shows an orbitally pivoted position for one of the two imaging arrangements 20 of imaging device 2 (dotted line). It may also be preferred, of course, that the second imaging arrangements 20 of imaging device 2 is also pivoted. In this preferred embodiment, a first photoactive system (on the left in FIG. 1b) is firstly produced, after which a second photoactive system to be produced (on the right in FIG. 1b) is imaged, without have to move imaging device 2 like in the embodiment shown in FIG. 1a. For that purpose, a first part of the at least one imaging arrangement 20 is aligned with the first photoactive system to be produced, and a second part of the at least one imaging arrangement 20 is aligned with a second photoactive system to be produced. The first and second parts of the at least one imaging arrangement 20 correspond, in particular, to a first and second subarea of a free aperture of the imaging module 21 of the respective imaging arrangement 20, in particular to a first and second subarea of a free aperture of an imaging arrangement 20 designed as a converging lens.

    [0139] In order to produce the photoactive systems according to the device 1 shown in FIG. 1b, the left and the right photoactive systems are alternately illuminated, and the image of the left hand photoactive system already adjusted and/or assembled and the image of the right-hand photoactive system still to be produced are superimposed in the imaging device, in particular physically, and, depending thereon, the photoactive system to be adjusted and/or assembled is adjusted via the first and/or second holding device 3a, 3b. An imaging arrangement 20 of such an imaging device 2 preferably includes a converging lens as imaging element 21.

    [0140] Based on an imaging device 2 with a single imaging arrangement 20, as an example, FIGS. 1c-1e show different preferred embodiments for alternately illuminating a first photoactive system (on the left in the Figure) and a second photoactive system (on the right in the Figure). This illumination concept is also applicable to devices 1, the imaging device 1 of which has two or more imaging arrangements 20 as shown schematically in FIG. 1b, for example.

    [0141] FIG. 1c shows a preferred schematic embodiment of device of device 1 with a rotatingly mounted shading unit 13a. The rotatingly mounted shading unit 13a alternately covers the left-hand and the right-hand photoactive system from the electromagnetic beams generated by beam source unit 22 (not shown in FIG. 1c). FIG. 1d shows a preferred schematic embodiment of device 1, in which a beam source 13b is arranged outside imaging device 1 and the electromagnetic beams z of which are coupled coaxially in such a way between beam passage plane SE and the first holding plane Ha that it alternately illuminates the left-hand and the right-hand photoactive system. FIG. 1d shows a preferred schematic embodiment of device 1, in which the left-hand and the right-hand photoactive system are illuminated alternately by means of optical fibres 13c, the light from the optical fibres preferably being coupled to the optical arrangement 12 of the photoactive systems 10 to be produced.

    [0142] The device 1 shown in FIG. 1f is designed to simultaneously capture two photoactive systems 10 to be produced. To that end, imaging device 2 in the device shown in this preferred embodiment has two imaging arrangements 20. In this preferred embodiment, the two imaging arrangements 20 are arranged substantially parallel with each other. In particular, the two imaging arrangements 20 of imaging device 2 are arranged in such a way that the optical axes O of the two imaging arrangements 20 are oriented substantially parallel with each other. The device shown in FIG. 1c includes two imaging arrangements 20, the optical axes O of which are oriented substantially orthogonally to the first and/or second holding plane. It should be understood that it may also be preferred that the two imaging arrangements with optical axes O are arranged at a slant relative to the first and/or second holding plane Ha, Hb. In this slanted orientation of the two imaging arrangements 20, their optical axes O are oriented parallel to each other. FIG. 1f shows schematically a pivoted position of imaging device 2 (dotted line).

    [0143] With the device 1 shown in FIG. 1f, it is possible, in particular, to produce two photoactive systems simultaneously. However, by means of a device 1 which includes more than two imaging arrangements 20 and more than two first and second holding devices 3a, 3b, it is also possible, to produce more than two photoactive systems.

    [0144] In order to produce two or more photoactive systems, images of the photoactive systems to be produced are captured. In order to produce the photoactive system still to be produced and/or assembled, an image of the photoactive system still to be produced is virtually superimposed by an image of the photoactive system already produced. The orienting of the photoactive system 10 still to be produced and/or assembled, in particular of the first and/or second holding device relative to the photoactive system already produced, is carried out simultaneously. This has the advantage that there is no need to store the images, and production time is saved.

    [0145] FIG. 2 shows another preferred embodiment of device 1 for producing a photoactive system. This preferred embodiment of device 1 is based on the preferred embodiment of device 1 shown schematically in FIG. 1, whose imaging arrangement 20 is focused by means of the imaging module at infinity in the direction of the first or second holding plane Ha, Hb. Unlike the device 1 shown schematically in FIG. 1, the device 1 shown schematically in FIG. 2 includes an imaging arrangement 20 having an imaging module 21 which focuses at finity in the direction of the first or second holding plane Ha, Hb on a second focal plane B2. The device 1 shown schematically in FIG. 2 is suitable, in particular, for producing a photoactive system which has an optical arrangement 12 that, arranged in the first holding device in the operating condition, focuses the electromagnetic beams reflected by photoactive arrangement 11 towards beam passage plane SE on a focal plane. In this device 1, the first holding device 3a having optical arrangement 12 arranged therein in the operating condition is positioned relative to the imaging arrangement such that the focal plane of the optical arrangement in the direction of beam passage plane SE corresponds to the second focal plane B2. The preferred embodiment shown schematically in FIG. 2 also has a test structure device 25. Such an embodiment is suitable, in particular, for producing photoactive systems 10 that include a low-contrast or reflecting photoactive arrangement 11. Normally, in the preferred embodiment shown, the electromagnetic beam is preferably split for illumination and for work with the test structure (not shown).

    [0146] The further preferred embodiment of a device 1 shown schematically in FIG. 3 comprises an imaging device 2, a first and second holding device 3a, 3b, an adjusting device 4, an evaluation device 5, a support device 6 and a joining device 7.

    [0147] The preferred embodiment of a device 1 for producing a photoactive system 10, shown schematically in FIG. 3, includes an imaging device 2 having two identical imaging arrangements 20. A first imaging arrangement 20 is positioned according to the imaging arrangement 20 of the preferred embodiment of device 1 shown schematically in FIG. 1. In particular, the first and second holding device 3a, 3b having the first and second holding plane Ha, Hb are positioned according to the preferred embodiment shown schematically in FIG. 1. A second imaging arrangement 20 of imaging device 2 is positioned at an angle relative to the first imaging arrangement 20, in particular relative to the first and/or second holding plane Ha, Hb of the respective holding device 3a, 3b. The two imaging arrangements 20 comprise an imaging module 21, a beam source unit 22, a beam splitter unit 23, and an image capturing unit 24. Image capturing unit 24 comprises a camera 24a, power electronics 24b and an image sensor 24c.

    [0148] In this preferred embodiment, beam source unit 22 is a point source of electromagnetic beams of visible light. In this preferred embodiment, beam source unit 22 can also emit non-visible light. In the operating condition, the electromagnetic beams generated by beam source unit 22 strike beam splitter unit 23. A diffuser unit 26 for scattering the electromagnetic beams is positioned between beam splitter 23 and beam source unit 22. Beam splitter unit 23 is positioned between imaging module 21 and image capturing unit 24. Beam splitter unit 23 deflects part of the electromagnetic beams towards imaging module 21. The electromagnetic beams generated by beam source unit 22 and deflected by beam splitter unit 23 exit imaging arrangement 20 through imaging module 21 arranged on beam passage plane SE. In the present preferred embodiment of device 1, imaging module 21 is designed to focus at infinity the electromagnetic beams emanating from the imaging arrangement. The optical arrangement 12 of the photoactive system to be produced focuses the electromagnetic beams focused at infinity on the photoactive arrangement, as previously described for the preferred embodiment of device 1 shown schematically in FIG. 1.

    [0149] The imaging module 21 of imaging arrangement 20 is also designed to focus, on a first focal plane B1, the electromagnetic beams reflected in the operating condition by photoactive arrangement 12. In the preferred embodiment of device 1 shown schematically in FIG. 2, the image capturing unit 24 of the imaging arrangement is arranged in such a way that an image sensor 24c of image capturing unit 24 is positioned relative to imaging module 21 in such a way that an image sensor 24c of image capturing unit 24 lies on the first focal plane B1 of imaging module 21. The image sensor 24c of image capturing unit 24 captures the evaluation image of electromagnetic beams reflected by photoactive arrangement 11. A filter unit 27 for filtering electromagnetic beams of a particular wavelength is provided between beam splitter unit 23 and the image capturing unit. It is preferred, in particular, that filter unit 27 allows short-wave electromagnetic beams, in particular beams in a narrow wavelength band only, to pass in the direction of the image capturing unit. This advantageously increases the imaging sharpness or a contrast of the respective evaluation image. Power electronics module 24b may be designed, in particular, to determine an imaging quality of the captured evaluation image and, depending on the determined imaging quality, to provide one or more control signals for controlling adjusting device 4. It may be preferred that the power electronics module 24b is coupled directly in signal communication with the adjusting device (not shown). In particular, power electronics module 24b can calculate the control signal using a conventional autofocus function of an image capturing unit 24 and provide it to adjusting device 4.

    [0150] In the preferred embodiment of device 1 shown schematically in FIG. 3, evaluation device 5 has an integrated electronic circuit 5a and a control unit 5b. Power electronics module 24b is designed to determine an imaging quality of the captured evaluation image and, depending on the determined imaging quality, to provide one or more control signals for controlling adjusting device 4. The control unit is designed to transmit the one or more control signals to the adjusting device 4 coupled in signal communication. Adjusting device 4 comprises a drive means 4a which preferably comprises one or more piezoelectric or electromagnetic actuators. In this preferred embodiment, other actuators would preferably be possible in addition or alternatively. Drive means 4a drives the first holding device 3a in response to the one or more control signals. Depending on the control signals, the orientation and/or position of the first holding device 3a is changed relative to the second holding device 3b until the evaluation image of photoactive arrangement 11 of the photoactive system 10 to be produced is adjusted in such a way relative to the optical arrangement 12 of the photoactive system 10 to be produced that a desired imaging quality is determined.

    [0151] To adjust the first holding device 3a relative to the second holding device 3b, the preferred embodiment of device 1 shown schematically in FIG. 3 includes a support device which is designed to support the first holding device 3a in such a way that, in the operating condition, the first holding device 3a can move the optical arrangement translationally along three axes oriented orthogonally to each other and rotationally about said three axes. It may be preferred for adjustment purposes that the first holding device 3a is translationally adjustable and that the second holding device is rotationally adjustable, or vice versa. It may also be preferred that both holding devices 3a, 3b have up to six degrees of freedom.

    [0152] The joining device is designed to assemble the adjusted photoactive system 10. In particular, the joining device is designed to joiningly connect the optical arrangement 12 of the adjusted photoactive system 10 to the photoactive arrangement 11 of the adjusted photoactive system 10 in the operating condition.

    [0153] The preferred embodiment of device 1 shown schematically in a side view in FIG. 4 and in a top view in FIG. 5 includes an imaging device 2 having four identical imaging arrangements 20. A first imaging arrangement 20 is positioned according to the imaging arrangement 20 of the preferred embodiment of device 1 shown schematically in FIG. 1. In particular, the first and second holding device 3a, 3b having the first and second holding plane Ha, Hb are positioned according to the preferred embodiment shown schematically in FIG. 1. The three other imaging arrangements 20 are arranged at an angle relative to the first imaging arrangement 20, preferably on a circular path (dashed/dotted line in FIG. 5).

    [0154] FIG. 6 shows a schematic top view of a photoactive arrangement 11 of a photoactive system 10 to be produced. The photoactive arrangement shown in FIG. 6 is produced by means of a device 1 according to FIGS. 4 and 5. The top view of photoactive arrangement 11 shows schematically the third focal plane B3 which is assigned to an imaging arrangement 20 of the device shown schematically in each of FIGS. 4 and 5. The respective third focal plane B3 is the respective image capture region of the four imaging arrangements 20, which is captured in order to generate the respective evaluation image and its evaluation. The crosses arranged in the image capture regions are adjustment marks which have been physically inserted immediately adjacent to the photoactive arrangement.

    [0155] A device 1 shown schematically in FIGS. 4-6 allows photoactive arrangement 11 to be adjusted relative to optical arrangement 12. To that end, a rough adjustment can firstly be made orthogonally to the focal plane B3 shown in FIG. 6 at the centre of the photoactive arrangement 11. When roughly focused, the distance between optical arrangement 12 and photoactive arrangement 11 is roughly adjusted. Based on the three adjustment marks, photoactive arrangement 11 is translationally oriented relative to optical arrangement 12 along the two axes. Photoactive arrangement 11 can then be oriented about two orthogonally oriented axes lying on focal plane B3. To that end, the imaging sharpness in the edge regions of photoactive arrangement 11 is preferably captured and the photoactive arrangement is adjusted, i.e. is rotated about said two axes, until the imaging sharpness in the edge regions is at least similar and preferably substantially identical. The aim, in particular, when performing the adjustment, is to achieve symmetry of the modulation transfer function of the respective edge region. It may also be preferred that the two aforementioned steps be performed in reverse order. Fine adjustment may then be preferred. When making the fine adjustment, the modulation transfer function is determined, in the present embodiment, in the four image capture regions and the value of the modulation transfer function is finely adjusted depending on preferences. It may be preferred that photoactive arrangement 11 be adjusted relative to optical arrangement 12 in such a way during fine adjustment that the imaging sharpness of imaging arrangement 20 is maximised for the central image capture region. However, it may also be preferred that photoactive arrangement 11 be finely adjusted relative to optical arrangement 12 in such a way that the imaging sharpness of one or more imaging arrangements 20 that capture one of the edge regions of photoactive arrangement 11 is maximised.

    [0156] FIG. 7 shows a schematic flow diagram of a first preferred embodiment of a method 100 for producing a photoactive system 10. This preferred embodiment of method 100 is suitable, in particular, for producing a deactivated photoactive system 10. The preferred embodiment includes the step of providing 101 a device 1 for producing a photoactive system 10, for example one of the preferred embodiments of device 1 described in the foregoing and shown schematically in FIGS. 1-6. The preferred embodiment of method 100 includes, as a further step, providing and arranging 102 a photoactive arrangement 12 in the second holding device 3b. The preferred embodiment of method 100 includes the further step of providing and arranging 103 an optical arrangement 12 in a first holding device 3a. This preferred embodiment feeds photoactive arrangement 11 and optical arrangement 12 of the photoactive system 10 to be produced to device 1. To that end, photoactive arrangement 11 and optical arrangement 12 are to be fed to the respective holding device 3a, 3b. The flow diagram shown schematically in FIG. 7 describes the logistics condition of device 1.

    [0157] The flow diagram shown schematically in FIG. 8 shows another preferred embodiment of method 100. This preferred embodiment of method 100 is based on the preferred embodiment of method 100 shown in FIG. 7. In addition to the steps of: providing 101 a device 1 for producing a photoactive system 10; providing and arranging 102 a photoactive arrangement 12 in the second holding device 3b; and providing and arranging 103 an optical arrangement 12 in a first holding device 3a, the method in the preferred embodiment shown schematically in FIG. 8 includes the steps of adjusting 110 the optical arrangement relative to the photoactive arrangement; and/or assembling 120 the optical arrangement adjusted relative to the photoactive arrangement; and/or testing 130 the optical arrangement assembled relative to the photoactive arrangement.

    [0158] The step of adjusting 110 may include one or more subordinate steps. A first preferred subordinate step in adjusting 110 is to provide 111 an electromagnetic beam for imaging an evaluation image of the photoactive arrangement 11 of the photoactive system 10 to be produced, or of the test structure. Another optional subordinate step in adjusting 110 is to image 112 the evaluation image of the photoactive arrangement 11 of the photoactive system 10 to be produced 10 on the beam passage plane (SE) of the at least one imaging arrangement 20. The step of adjusting 110 may include capturing 113 the evaluation image on the beam passage plane SE of the at least one imaging arrangement 20. In particular, the method of adjusting 110 includes evaluating 114 the captured evaluation image. Finally, a fifth preferred subordinate step in adjusting 110 is to move 115 the first holding device 3a with optical arrangement 12 disposed therein and/or the second holding device 3b with photoactive arrangement 11 disposed therein, depending on the evaluation of the captured evaluation image. The steps of adjusting 110 are preferably performed iteratively.

    [0159] The step of assembling 120 includes, in particular, the step of connecting the optical arrangement 12 to the photoactive arrangement 11 of the photoactive system 10 to be produced. In particular, it may be necessary when carrying out the step of assembling 120 or adjusting to take into account any shrinkage of the connection or the like during assembly, by providing an offset that compensates for the shrinkage. Shrinkage of the connection results, for example, from heat input, for example during soldering or welding or gluing. When gluing, such shrinkage ensues, for example, during the phase transition from a liquid to a solid aggregate state of an adhesive used for gluing.

    [0160] The step of testing 130 includes one or more optional subordinate steps. The step of testing 130 includes, in particular, providing 111 an electromagnetic beam for imaging an evaluation image of the photoactive arrangement 11 of the photoactive system 10 to be produced. Testing 130 also includes imaging 112 the evaluation image of the photoactive arrangement 11 of the adjusted and/or assembled photoactive system 10, or of the test structure, on the beam passage plane SE of the at least one imaging arrangement 20. Testing 130 may also include capturing 113 the evaluation image of the at least one imaging arrangement 20. It is preferred, in particular, that testing includes evaluating 114 the captured evaluation image as a subordinate step.

    [0161] The step of evaluating 114 the respective captured evaluation image includes the following steps in particular: determining a frequency response characteristic of the captured evaluation image; and/or comparing the captured evaluation image with a captured evaluation image of a photoactive system already adjusted and/or assembled according to the method previously described; wherein, in particular, the evaluation images are captured simultaneously or sequentially in the respective at least one imaging arrangement 20; wherein, in particular, the comparison of the simultaneously captured evaluation images is based on a physical superimposition in the respective at least one imaging arrangement 20; and/or in particular the comparison of the simultaneously or sequentially captured evaluation images is based on virtual superimposition in the respective at least one imaging arrangement 20; and/or comparing the captured evaluation image and/or the determined frequency response characteristic of the captured evaluation image with a desired target state.

    [0162] The step of evaluating 114 the respective captured evaluation image includes, in particular, generating a control signal for moving the first and/or second holding device. The control signal is generated, in particular, according to a comparison of the captured evaluation image with a captured evaluation image of a photoactive system already adjusted and/or assembled according to the previously described method and/or according to a determined frequency response characteristic and/or a determined offset; and/or according to a comparison of the captured evaluation image with a desired target state, if the captured evaluation image does not match the desired target state; and/or according to a comparison of the determined frequency response characteristic of the captured evaluation image with a desired target state, if the frequency response characteristic of the captured evaluation image does not match the desired target state.

    [0163] It may also be preferred that the method preferably includes the further step of moving imaging device 2 (not shown), in order to successively and/or simultaneously produce a plurality of photoactive systems 10 to be produced relatively to each other.
