Abstract

The invention provides a two-dimensional adjustable mirror frame based on curved surface positioning. The solution includes a main mirror frame, a locking ring and a mirror frame; the mirror frame is sleeved in the main mirror frame; one side of the mirror frame is connected with the main mirror frame, and One side is covered with a locking ring; the inner edge of the main mirror frame is provided with internal threads; the outer edge of the locking ring is provided with external threads matching the internal threads of the main mirror frame; the locking ring and the main mirror frame are threaded connected; lenses are arranged in the frame. This solution can solve the problem of low structural rigidity in the two-dimensional adjustable optical mirror frame, which makes it difficult to improve the anti-resonance stability of the mirror frame, especially the problem of resonance amplification for low-frequency vibrations. Practice shows that the invention can effectively improve the fundamental frequency of the frame structure, and at the same time ensure the precise two-dimensional angle adjustment of the lens around the x-axis and y-axis, and improve the stability of the frame structure.

Description

technical field [0001] The invention relates to precision optical element assembly and adjustment technology, in particular to a two-dimensional adjustable mirror frame based on curved surface positioning. Background technique [0002] In the prior art, it is known that the currently commonly used two-dimensional adjustable optical mirror frame has low stiffness and low resonance frequency. In a random vibration environment, structural resonance is likely to occur, which in turn affects the beam transmission accuracy. This is the current There are deficiencies in technology. Contents of the invention [0003] The purpose of the present invention is to provide a technical solution of a two-dimensional adjustable mirror frame based on curved surface positioning, which can solve the problem of low structural rigidity in two-dimensional adjustable optical mirror frames. It is difficult to improve the anti-resonance stability of the mirror frame, especially the problem of reso...
