Embodiment Construction

[0060] Planar mirrors are components commonly used in optical systems, mainly used to achieve transitions of the beam, and change the direction of the beam. By adjusting the angle of the planar mirror, the direction of the reflected light can be changed, thereby affecting the effect of the optical system. However, the conventional planar mirror adjustment device cannot quantify the planar mirror, so the accuracy of the plane of the plane mirror is not high. The planar mirror system provided herein is intended to solve the above technical issues of traditional techniques.

[0061] In order to make the purpose, technical solutions and advantages of the present application, the present application will be described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

Abstract

The present application provides a plane mirror system, which includes a support frame, a plane mirror device and a first trimming device. The supporting frame includes a bottom plate and two supporting arms arranged at intervals. The plane mirror device is rotatably installed between the two support arms. The first fine adjustment device includes a first fine adjustment frame, a first retractor and a first spring. The first fine-tuning frame is rotatably installed between the two support arms, and the first fine-tuning frame and the plane mirror device have a common first rotation axis. The first fine-tuning device of the plane mirror system provided in the present application can quantitatively adjust the rotation angle of the plane mirror device around the first rotation axis, and improve the degree of rotation of the plane mirror device around the first rotation axis. The accuracy of the rotation further shifts the direction of the reflected light, improving the accuracy of adjusting the direction of the reflected light.

Description

Technical field [0001] The present application relates to the field of optical instruments, in particular to a planar mirror system. Background technique [0002] Planar mirrors are commonly used optical components that have a very important position in optical instruments. In the optical system, the planar mirror is mainly used to achieve a turning point of the beam, and change the direction of the beam. Since the working surface of the planar mirror is a plane, the change in plane mirror angle makes the direction of the reflected light changes, thereby affecting the effect of the optical system. [0003] The conventional planar mirror adjustment device adjusts the angle of the mirror by turbine and worm, thereby changing the direction of the reflected light to obtain reflected light in the requirements direction. [0004] However, the conventional planar mirror adjustment device cannot perform quantitative adjustment, and the accuracy of the plane mirror angle adjustment is not...
