Problems solved by technology
The mirror flatness requirement of the mirror is one of the important factors to ensure the stability of the measurement beam and the accuracy of the optical measurement results. The existing processing technologies for various optical mirrors can already guarantee the manufacture of mirrors that meet the requirements, but When the mirror is clamped, once it is clamped improperly, the mirror will inevitably warp and deform, resulting in a deviation in the optical path of the measuring beam refracted by its mirror surface, which has a serious impact on the accuracy of the measurement results
In addition, when the measurement device is in a situation where the measurement condition is not good, such as frequent vibration, if the mirror is not firmly clamped, the lens will often loosen and shift or even fall from its fixing bracket, causing the optical system to fail, and then Greatly affects the measurement efficiency

Embodiment Construction
[0018] A mirror clamping device, comprising a bracket 20 for fixing the mirror 10, the bracket 20 is provided with a limiting part that restricts the movement of the mirror 10 along the parallel direction of its mirror surface, and the bracket 20 is provided with There is a clip 21 at the edge of the restrictive reflector 10, and a support portion 22 is also provided on the bracket 20 corresponding to the clip 21. The support portion 22 and the clip 21 constitute a mechanism for limiting the movement of the reflector 20 in the vertical direction of the mirror surface. limit fit, such as figure 1 and Figure 8 shown.
[0019] As a further preferred solution of the present invention, its supporting part 22 is arranged between the mirror back of the reflecting mirror 10 and the bracket 20, and one end of the clip 21 is fixedly connected to the bracket 20, and the other end is stuck against the mirror surface of the reflecting mirror 10. From then on, the clip 21 is stuck betwee...

The invention belongs to the field of optical components, in particular to a clamping device for an optical reflector. The invention includes a bracket for fixing the reflector, the bracket is provided with a limiting part that restricts the movement of the reflector along the parallel direction of its mirror surface, and the bracket is provided with a clamp that restricts the position of the edge of the reflector, and the clamp is opposite to the clamp. A supporting part is also provided on the corresponding bracket, and the supporting part and the clip form a position-limiting fit that limits the movement of the reflector along the vertical direction of the mirror surface. The effect of limiting the spatial displacement of the reflector is achieved by limiting the parallel and vertical movement of the reflector in space, so as to achieve the purpose of reliably clamping and fixing the reflector in the present invention.
Description
technical field [0001] The invention belongs to the field of optical components, in particular to a clamping device for an optical mirror. Background technique [0002] In the existing field of optical components, various optical lenses such as mirrors are frequently used. Especially in optical measurement instruments, with the increasingly advanced optical measurement system, the accuracy of optical measurement data is increasing, and the requirements for reflectors are also getting higher and higher. The mirror flatness requirement of the mirror is one of the important factors to ensure the stability of the measurement beam and the accuracy of the optical measurement results. The existing processing technologies for various optical mirrors can already guarantee the manufacture of mirrors that meet the requirements, but When the mirror is clamped, once it is clamped improperly, the mirror will inevitably warp and deform, resulting in deviation of the optical path of the me...
