Method of assembling an optical device in which a circuit board is provided supporting an imager, and a support is provided for supporting the circuit board. A first adhesive layer is applied to a mating region of at least one of the circuit board and the support. The circuit board is fixed to the support using at least one fastener. The first adhesive layer is compressed between the mating regions once the circuit board is fastened. The first adhesive layer is then cured for forming a stabilised imager assembly. A lens is then fixed to the stabilised imager assembly using a second adhesive layer, where fixing includes positioning the lens on the support to align its focal plane with the imager and then curing the second adhesive layer.

A modular vision system that can include a housing with a faceplate and a first and second optical module mounted to the faceplate. Each of the first and second optical modules can include a mounting body, a rectangular image sensor, and an imaging lens that defines an optical axis and a field of view. The first optical module can be configured to be mounted to the faceplate in a first plurality of mounting orientations and the second optical module can be configured to be mounted to the faceplate in a second plurality of mounting orientations. The first and second optical modules can thus collectively provide a plurality of imaging configurations.

A system includes a diffractive optical element configured to receive a first beam and a second beam interfering with one another to generate a first interference pattern. The diffractive optical element is also configured to forwardly diffract the first beam and the second beam to output a third beam and a fourth beam. The third beam and the fourth beam interfere with one another to generate a second interference pattern. The system also includes a detector configured to detect the second interference pattern.

A telecentric optical apparatus that is capable of suppressing an increase in the number of components as well as achieving high precision optical axis alignment, is provided. The telecentric optical apparatus of the present invention is characterized in that it is provided with: a first telecentric lens surface that is provided on an object side; a second telecentric lens surface that is provided on an image side and that shares a focus position with the first telecentric lens surface; and an optical path trimming part that is provided, between the first telecentric lens surface and the second telecentric lens surface, in an outside region, which is located on a side further out than a light passing region having a center thereof located at the focus position, and that changes an optical path such that a light beam incident on the outside region is prevented from contributing to image formation.

An optical element adjustment device includes a casing base, an optical element, a bearing element, and a first adjustment module. The optical element is movably disposed in the casing base. The bearing element includes an outer frame bearing the optical element and a shaft portion protruding from the outer frame and penetrating from the casing base. The first adjustment module is disposed on the shaft portion. A screw shank is sleeved on the shaft portion and penetrates from the casing base. The first adjustment element is screwed to the screw shank and abuts against the casing base. A limiting element protrudes from a side surface of the shaft portion and is located next to the screw shank. The first elastic element is disposed between the screw shank and the outer frame, such that the screw shank leans closely to the limiting element.

An optical lens (1), comprising a first lens (100) and a lens assembly (110). The first lens (100) includes a first optical area (101) and a first structural area (102) surrounding the first optical area (101), and the first structure area (102) includes a height measurement area (103) not coated with an anti-reflective coating. The lens assembly (110) includes a lens barrel (104) and at least one second lens (105) disposed in the lens barrel (104). The at least one second lens (105) includes a second optical area (106) and a second structural area (107) surrounding the second optical area (106). The first structural area (102) is connected to an end face (109) of the lens barrel (104) near the first lens (100) or the second structural area (107) of the second lens (105) closest to the first lens (100). A manufacturing method of optical lens (1) and a camera module are also disclosed.

The present teachings provide an image capture device including a bayonet and an integrated sensor and lens assembly (ISLA). The bayonet is connected to a body of the image capture device. The ISLA is connected to the bayonet. All or a portion of the ISLA extends into the body of the image capture device. The ISLA includes a lens assembly having a forward end and a rearward end and an integrated sensor. The integrated sensor is connected to the rearward end of the lens assembly. Fasteners extend through the bayonet into the forward end of the lens assembly to connect the ISLA to the bayonet.

A method of manufacturing a lens including forming a cover blank having cover parts by injecting a thermosetting first resin in a first mold and curing the thermosetting first resin, removing a part or all parts of the first mold, and arranging the cover blank in a second mold. The method further includes forming a lens blank having a light-shielding part between adjacent cover parts by injecting a thermosetting second resin having a greater light absorptance or light reflectance than the thermosetting first resin into the second mold and curing the thermosetting second resin, and obtaining individual lenses by taking out the lens blank from the second mold, and cutting the lens blank at the light-shielding part located between adjacent cover parts to obtain individual lenses each with lateral end surfaces and an upper surface of each of flange parts and lateral side walls covered by the light-shielding part.
