The invention comprises a hands-free, adjustable telescoping magnifying mirror. The mirror may have a first reflective surface and a second reflective surface and can be secured to a horizontal or vertical surface using a suction cup base or can be hung over a door or ledge using a retractable hanger bracket. A telescoping rod is attached to the suction cup base. The mirror may be extended from the base by extending the telescoping rod and the mirror assembly can stand freely without falling over, whether the suction cup base is engaged or not. Additionally, one or more light sources may be disposed at a periphery of the first reflective surface or second reflective surface.

Method and a device capable of recovering vision, the method comprising: dividing a diopter variation range [0/100, N/100]D into n diopter intervals with continuous diopter variation, and setting the diopter variation ranges to [0/100, (N/n)/100]D, [(1+N/n)/100, (2N/n)/100]D, . . . , and [(1+(n−1)N/n)/100, N/100]D, N]; manufacturing a pair of glasses according to the vision recovery requirement of a user, wherein the diopter variation ranges of the left lens group and the right lens group of the glasses respectively correspond to one diopter interval of the n diopter intervals, so that power of the glasses can be changed with high precision; for either of the lens group, determining an adjustment amount according to a desired diopter of the user and a current diopter of the glasses; according to the adjusting amount, driving the movable lens to move by an electric drive module arranged in the glasses, so that the user can independently and accurately adjust the power in an electric control mode.

An actuator device for aligning an element includes at least one first actuator unit, which is secured to a support structure, for a first setting range and a second actuator unit, which is able to be secured to the element, for a second setting range. The second actuator unit is connected to an output element of the first actuator unit so that the positioning of the second actuator unit is adjustable by an adjustment of the output element. The first actuator unit has an adjusting element and a fixing element, which is able to be secured to the support structure. The fixing element secures the output element in a force-locking manner in an operating state of the element. The fixing element is furthermore configured to release the force-locking connection in a setting state of the element to enable an adjustment of the output element via the adjusting element.

A method adjusts a first element of a lithography apparatus toward a second element of the lithography apparatus via a tunable spacer which is arranged between the first element and the second element. The method includes: determining an actual location of the first element; determining a nominal location of the first element; unloading the tunable spacer; adjusting a height of the tunable spacer to bring the first element from the actual location to the nominal location; and loading the tunable spacer.

In a beam splitter assembly 7, a beam splitter 22 is supported at three points by three bent portions 41 of a first spacer 24. Therefore, the beam splitter 22 can be prevented from being affected by the surface accuracy of a holder 21. Further, in the beam splitter assembly 7, the first spacer 24 faces the peripheral edge portion of the beam splitter 22. Each bent portion 41 is configured by bending each outer projection piece. Therefore, the external shape of the first spacer 24 can be prevented from becoming larger than the external shape of the beam splitter 22. And it is possible to suppress that the size of the holder 21 for providing the first spacer 24 becomes large. As a result, the miniaturization of the beam splitter assembly 7 can be realized.

Kinematic mounts are used frequently to hold objects such as mirrors, lenses, and other optical equipment. To adjust kinematic mounts, adjustment mechanisms are often required. Adjustment mechanisms can be used to make fine adjustments in applications where precision is required (e.g., laser system prototyping). Kinematic mounts that include never-before implemented form factors and structural elements require new adjustment solutions. This application describes systems that include both novel kinematic mounts as well as new adjustment mechanisms developed to reorient the new kinematic mounts. Adjustment mechanisms described in this application include a main body, a control frame, and control screws to adjust the orientation of the control frame. The control frame is coupled with a kinematic mount's housing, which rotates about a center of curvature of a bottom surface of the housing.
