Description

A kind of catoptron clamping device

Technical field

The invention belongs to the optical component field, be specifically related to a kind of clamping device of optical mirror.

Background technology

In the existing optical component field, extremely frequent to the application of various optical mirror slips such as catoptron etc.Especially in the optical measurement quasi-instrument, advanced day by day along with the optical measurement system improves day by day to the precision of optical measurement data, and be also just more and more higher to the requirement of catoptron.It then is to guarantee one of key factor that measuring beam is stable and even whether accurate optics survey result is that the minute surface flatness of catoptron requires, the process technology of existing various optical mirrors can guarantee to produce satisfactory eyeglass, but when carrying out the catoptron clamping, in case clamping is improper, buckling deformation still can inevitably take place in catoptron, the light path generation deviation that causes the measuring beam after the refraction of its minute surface has a strong impact on thereby the accuracy of measurement result caused.In addition, when measuring element was in frequent vibration etc. and measures in poor shape occasion, if the catoptron clamping is firm inadequately, its eyeglass often will instead be given birth to loose shift even be fallen the road from its fixed support, cause the light path system fault, influenced efficiency of measurement then greatly.

Summary of the invention

The clamping device that the purpose of this invention is to provide a kind of optical mirror can reach the purpose of reliable clamping catoptron.

For achieving the above object, the present invention has adopted following technical scheme: a kind of clamping device of catoptron, comprise the support that is used for fixing catoptron, support is provided with the limiting section that the restriction catoptron moves along the parallel direction of its minute surface, described support is provided with the mounting board of about beam steering mirror edge position, with also be provided with the support portion on the corresponding support of mounting board, described support portion and mounting board are construed as limiting the spacing cooperation that catoptron moves along the minute surface vertical direction.

Beneficial effect of the present invention is: after adopting said structure, reach the effect that limits its space displacement by the parallel and vertical movement spatially of restriction reflective mirror, to realize the purpose of reliable clamping of the present invention and stationary mirror.
