Abstract

The invention provides a multi-degree-of-freedom optical mirror frame for optical path adjustment, which includes pitch and yaw devices, up and down moving devices, left and right moving devices and forward and backward moving devices. The adjusting mirror frame provided by the present invention has the characteristic of modularization, and its key structure can be intercepted to produce an adjusting mirror frame suitable for a reflecting mirror or a transmitting mirror. Overcoming the shortcomings of the manual optical adjustment frame provided by the traditional technology, the reset mechanism is improved, and the reset spring is no longer used but the screw is fixed. After the optical path adjustment is completed, the moving plate and the fixed plate of the main part of the frame are connected by screws. Together, this increases the long-term stability of the frame for engineered applications of the laser. The solution is low in cost and easy to implement. The adjustment mirror frame can be used to debug and maintain the laser light path, quickly and conveniently collimate the laser, and obtain high-precision laser output.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an optical mirror frame for optical path adjustment. Background technique [0002] Optical path adjustment is an important part in the laser field. Its main function is to adjust the lens according to the azimuth, pitch and angle of the optical path, so that the optical path propagates in a predetermined direction. [0003] Traditionally commonly used manual optical adjustment frames are mainly divided into main parts (moving plate, fixed plate), driving mechanism (thread pair), guiding mechanism (guide rail), reset mechanism (return spring), locking mechanism and other parts. Its working principle is that the screw pair of the driving mechanism converts the rotary motion into the linear movement of the moving plate to drive the movement of the lens. During the adjustment process, the pressure generated by the screw pair driving the moving plate and the elastic force generated b...
