Optical device adjusting device

Abstract

The present disclosure provides an optical device adjustment apparatus, comprising: a base adapted to hold an optical device; a first adjusting mechanism constructed to support the base and drive the base to move in the first direction; a second adjusting mechanism constructed to support the first adjusting mechanism and drive the first adjusting mechanism to move in the second direction perpendicular to the first direction; an upright frame; and a third adjusting mechanism which is mounted on the upright frame and is configured to support the second adjusting mechanism and drive the second adjusting mechanism to move along a third direction perpendicular to the first direction and the second direction relative to the upright frame. The optical device adjusting device is used for clamping an optical device and can adjust the degree of freedom of linear movement of the optical device in three directions, the adjusting process of the optical device adjusting device is simple, the adjusting processes in the three directions do not interfere with one another, and decoupling adjustment in the three directions is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of mechanical structures, in particular to an optical device adjustment device. Background technique [0002] Optical devices are often equipped with many optical components and optical devices, and optical devices (such as lenses, mirrors, and half-mirrors) usually need to be arranged in groups of two. During the assembly and use of optical equipment, the accuracy of the spatial relative position between two optical devices arranged in groups is relatively high; however, there will be more accumulated errors in the design, manufacture and assembly process of the adjustment device of the optical device , so that the adjustment device may easily lead to inaccurate spatial relative positions between the two optical components during use. The existing adjustment device usually has only one degree of freedom, that is, it can only adjust the straight-line distance in one direction between two optical de...

Problems solved by technology

During the assembly and use of optical equipment, the accuracy of the spatial relative position between two optical devices arranged in groups is relatively high; however, there will be more accumulated errors in the design, manufacture and assembly process of the adjustment device of the optical device , so that the adjustment device is easy to cause inaccurate spatial relative positions between the two optical devices during use

The existing adjustment device usually has only one degree of freedom, that is, it can only adjust the straight-line distance in one direction between two optical devices, therefore, it is impossible to determine the spatial relative position between two grouped optical devices

In addition, the current multi-degree-of-freedom adjustment device has coupling problems during the adjustment process, and the adjustment process is extremely complicated
