Abstract

The invention discloses a fixing device and a fixing method for a prism of corner cube. The fixing device comprises a clamp, an apron, a base, a lock nut and a holding screw. A hollow hole with a circum-circle diameter less than a bottom diameter of the prism of corner cube is arranged in the clamp and is used for placing the prism of corner cube. A hollow hole with an opening containing inner screw threads is arranged in the base and is used for placing the prism of corner cube and the clamp. The inner hole diameter of the lock nut is slightly less than the circum-circle diameter at the bottom of the prism of corner cube. The gap between the whole length of the hollow hole of the base and the length of the assembled prism of corner cube and clamp is less than the inner screw thread length of the base. The lock nut matches with the base through the inner and exterior screw threads and tightly locks the prism of corner cube in axial direction. The holding screw is screwed in the screw holes in the exterior wall of the base to tightly hold the clamp and prevent the clamp from rotating in the axial direction. The fixing device and a fixing method fully make use of the three orthogonal seamed edges of the prism of corner cube, adopts the three contact styles containing point contact, line contact and surface contact to realize the precisely-fixed prism of corner cube, and has the advantages of simple structure, convenient installation and detachable installation.

Description

technical field [0001] The invention relates to an installation and adjustment device of an optical element, in particular to a fixing device with a clamp for a corner cube prism. Background technique [0002] The corner cube prism, also known as the retroreflector, is an internal total reflection prism manufactured according to the principle of critical angle. It is not affected by the size of the incident angle, and reflects the incident light back in parallel to the original direction. Since the shape of the corner cube is not a regular cylinder or cuboid, and it is a glass product, it is brittle and easily broken, so it is difficult to install and fix it by mechanical means. [0003] The optical component product catalog published by EDMUND OPTICS of the United States in 2004 proposed a method and device for installing a corner cube (this product manual can also be retrieved through the following website: http: / / www.edmundoptics.com / onlinecatalog / displayproduct.cfm?pro...
