Problems solved by technology

However, for the prism components in optical instruments, the adjustment mechanism used requires convenient adjustment, high adjustment accuracy, and good stability, and the adjustment mechanism is often limited by the space position. It is difficult for the finalized products on the market to fully meet these requirements.

Abstract

The invention relates to a prism pose adjustment mechanism. Including the static seat, locking screw sleeve, moving seat, and prism rotating shaft arranged sequentially from outside to inside in the overall axial direction of the mechanism; Three-dimensional adjustment between the movable seat and the static seat through three-top three-pull or two-top two-pull or screw pressure spring push structure; the prism shaft and the movable seat cooperate with the cylindrical surface to realize the angular displacement adjustment around the axis, and the locking nut is used The degree of freedom is locked; the prism shaft and the movable seat are pre-tightened in the axial direction through a pre-tightening screw group; the lower end of the prism shaft is bonded with a cubic prism through a structural adhesive. The invention provides a prism pose adjustment mechanism capable of realizing four-dimensional adjustment.

Description

Technical field [0001] The invention belongs to the field of optical precision instruments, and relates to a prism, in particular to a prism posture adjustment mechanism. Background technique [0002] In the design of optical instruments, the position and direction of the optical axis of the system are often changed through a prism according to the needs of the actual optical path. Prism posture adjustment is realized by a prism posture adjustment mechanism. As a modular optical part, a prism is often used as its posture adjustment mechanism in the laboratory. At present, there are many enterprises dedicated to the research and development of multi-dimensional adjustment tables in the domestic and foreign markets. The products of these enterprises can basically meet the needs of prism pose adjustment in laboratory optical experiments and testing. However, for the prism components in optical instruments, the adjustment mechanism used in it requires convenient adjustment, high adj...
