Abstract

The invention provides a multiple degree of freedom optical frame for optical path adjustment. The frame comprises a pitch and yaw device, an up and down moving device, a left and right moving device,and a front and rear moving device. An adjustment frame provided by the invention has a modular characteristic. The adjustment frame suitable for a reflecting mirror or a transmission mirror can be produced by intercepting a key structure thereof. The shortcomings of a manual optical adjustment frame provided by the traditional technology are overcome. A reset mechanism is improved by using a screw fixing mode instead of return springs. When the optical path adjustment is completed, a moving plate and a fixing plate of a frame body are connected by screws, so as to increase the long-term stability of the frame. The reset mechanism can be used as an engineering application of laser devices. The scheme is low in cost and easy to realize. By using the adjustment frame, an optical path of a laser can be debugged and maintained, and the laser can be collimated quickly and conveniently to obtain a 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...
