Elastic connection component for optical use and regular polygonal prism using same

Abstract

The invention relates to the field of optical mechanical precision measuring instruments, in particular to an elastic connection component for optical use and a regular polygonal prism using the same. In order to solve the problem of high-flatness optical component deformation caused by optical component connection in the prior art, the invention provides the elastic connection component for optical use and the regular polygonal prism using the same, wherein the elastic connection component for optical use has reasonable structure and enables the high-flatness optical component deformation degree to be low. The elastic connection component for optical use is characterized by also comprising an installing seat (16) and an elastic claw (14), wherein the bottom of the installing seat (16) isused for fixed connection, and the side surface of the elastic claw (14) is used for elastically bonding a plane reflector (13). The regular polygonal prism using the elastic connection component is characterized in that a plurality of elastic connection components for optical use are uniformly distributed on an upper side surface of a base (11). The invention uses the separating structure to enable various kinds of force to be transmitted to the high-flatness plane reflector through the elastic claw, thereby reducing the high-flatness optical component deformation caused by optical componentconnection. The elastic connection component can be applied to the elastic connection field of high-flatness optical component of the regular polygonal prism.

Description

technical field [0001] The invention relates to the field of optical-mechanical precision measuring instruments, in particular to an optical elastic connection component and a regular polyhedron using the component. Background technique [0002] The regular polyhedron is a commonly used angle measuring instrument. It is mainly used for the value transfer of angles, angle verification instruments, machine tool indexing tables and special equipment; because it is a pure optical machine structure, the angle is not affected by speed and acceleration, so it is also used as a standard instrument for angle dynamic measurement and "arrangement Comparing with each other method", and the prism angle error separated by the dynamic "arrangement and mutual comparison method" can be compared with the static verification data to verify the accuracy of the dynamic verification. [0003] Among the many technical indicators of the regular polyhedral prism, the most critical indicator is the ...

Problems solved by technology

Therefore, once the flatness of the optical parts deteriorates, it often needs to be replaced, and repairs are often difficult, because not only the cost is high but also the stability is poor, because in addition to the internal stress of the material itself, the elastic force of the residual deformation is increased, so even if it is repaired It also takes a long time to stabilize before it can be carried out, which will cause a lot of trouble for scientific research and production, so the best way is to adopt a reasonable structural design to prevent deformation of high-flatness optical parts

In short, in the prior art, there is no report on how to prepare a quadratic prism that meets the requirements of a flatness not greater than 0.03 μm, a roughness not greater than 0.025 μm, and a working surface size not less than Φ15 mm, that is, a quadratic prism. What kind of reasonable structure should be adopted? Design to meet the above requirements is a problem that needs to be solved at present
