Optical element angle fine adjustment mechanism

Abstract

The invention discloses an optical element angle fine adjustment mechanism which comprises a square frame and a first angle adjustment assembly. Pin shafts symmetrically penetrate through the middles of the two sides of the square frame, a round frame is arranged between the pin shafts on the two sides, an optical element is arranged in the round frame, a second angle adjusting assembly is arranged at the bottom of the square frame, a height adjusting assembly and a limiting assembly are arranged on the second angle adjusting assembly, and a horizontal adjusting assembly is arranged at the bottom of the height adjusting assembly. The first angle adjusting assembly comprises a middle groove, a limiting shaft, a transmission gear, an arc-shaped plate, a guide rail and a guide rod, the middle groove is formed in the middle of the top face of the square frame, the limiting shaft is arranged in the middle groove, the limiting shaft is movably sleeved with the transmission gear, the arc-shaped plate is arranged at the top of the round frame, and meshing teeth are evenly arranged on the arc face of the arc-shaped plate. According to the optical element angle fine adjustment mechanism, the angle adjustment range can be effectively expanded, the use requirement can be better met, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of optical element adjustment, in particular to an optical element angle fine adjustment mechanism. Background technique [0002] Optical components are the basic components of the optical system. Most of the optical components play the role of imaging, such as lenses, prisms, mirrors, etc., and some have special functions in the optical system (such as light splitting, image transmission, filtering, etc. Parts, such as reticles and filters, etc., in order to improve the imaging quality of some optical components, the angle and position of the optical components need to be fine-tuned. The angle adjustment mechanism of some existing optical components is relatively simple, and the angle adjustment range is relatively limited. It is too large to meet the needs of users. Therefore, we propose a fine-tuning mechanism for the angle of optical components. Contents of the invention [0003] The technical problem...
