Press plate for fixing optical components

Abstract

A pressure plate used for fixing optical components of an optical table with threaded holes, comprising a pressure plate main body integrated with a square cylinder and a quasi-cylindrical body, height adjustment bolts and fastening bolts, the square column of the pressure plate main body The upper surface of the body is provided with a vertically downward height adjustment threaded hole and a waist slot hole, the upper surface and the rear surface of the quasi-cylindrical body are small planes, and the front surface and the lower surface are cylindrical surfaces; that is, the quasi-cylindrical body The end surface of the body is an eccentric quasi-circular surface relative to the main axis of the main body of the pressure plate, while the end surface of the square cylinder is a square plane, and the height adjustment threaded hole is used for screwing in the height adjustment bolt. , the waist slot holes are used for the fastening bolts to pass through from top to bottom. The present invention can fix optical components whose surfaces are planes, slopes, circular arcs, etc. and have different thicknesses during optical path adjustment, and has the characteristics of simple structure, convenient use and firm fixing.

Description

technical field [0001] The invention relates to an optical instrument, in particular to a pressure plate used for fixing optical components of an optical platform with threaded holes, which can be used to fix the optical surface of a base with a flat surface, an inclined surface, an arc surface, etc. and with different thicknesses during the adjustment of the optical path. Components have the characteristics of simple structure and firm fixation. Background technique [0002] In the optical path adjustment, because the position of the optical components is uncertain, the adjustment range is large, and the fixing method of the pressure plate is flexible and convenient, and it is widely used; however, the ordinary pressure plate can only be used to fix the plane, and the device with the base of the inclined surface and the arc surface Can not be fixed, the application is limited; Contents of the invention [0003] The object of the present invention is to provide a clamping...
