Embodiment Construction

[0060] Plane mirrors are commonly used components in optical systems, which are mainly used to realize the turning of the beam and change the direction of the beam. By adjusting the angle of the flat mirror, the direction of the reflected light can be changed, thereby affecting the effect of the optical system. However, the conventional flat mirror adjustment device cannot quantitatively adjust the flat mirror, and therefore, the accuracy of the angle adjustment of the flat mirror is not high. The flat mirror system provided by the present application aims to solve the above technical problems of the conventional technology.

[0061] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present applicati...

Abstract

The invention provides a plane mirror system comprising a supporting frame, a plane mirror device and a first fine adjusting device. The supporting frame comprises a baseplate and two supporting armswhich are arranged in a spaced way. The plane mirror device is rotatably installed between the two supporting arms. The first fine adjusting device comprises a first fine adjusting framework, a firstretraction device and a first spring. The first fine adjusting framework is rotatably installed between the two supporting arms. The first fine adjusting framework and the plane mirror device have a common first rotating shaft. According to the plane mirror system, the first fine adjusting device can quantitatively adjust the rotation angle of the plane mirror device around the first rotation shaft to enhance the rotation accuracy of the plane mirror device around the first rotation shaft so that the direction of the reflected light is enabled to be shifted and the adjustment accuracy of the light emergent direction of the reflected light can be enhanced.

Description

technical field [0001] The present application relates to the field of optical instruments, in particular to a flat mirror system. Background technique [0002] Plane mirror is a common optical component and plays a very important role in optical instruments. In the optical system, the plane mirror is mainly used to realize the turning of the beam and change the direction of the beam. Since the working surface of the plane mirror is flat, the change of the angle of the plane mirror will change the direction of the reflected light, thereby affecting the effect of the optical system. [0003] The traditional plane mirror adjustment device adjusts the angle of the mirror through the cooperation of the turbine and the worm, so as to change the direction of the reflected light and obtain the reflected light in the required direction. [0004] However, the traditional flat mirror adjustment device cannot perform quantitative adjustment, and the precision of the angle adjustment ...
