Abstract

The invention relates to an optical instrument mirror group switching device, in particular to a trapezoidal mirror group array, which solves the problems that the existing optical unit and diaphragm switching occupy a large space and the switching precision is low. The technical solution adopted in the present invention is: a trapezoidal mirror group array, including a base, a support frame, an optical unit and an aperture; the base is a first mobile platform that moves along the X-axis direction; the support frame is arranged on the base, and the support frame One side is provided with an N-level step surface, and the other side is provided with an aperture mesa, N is greater than or equal to 2, and the preferred value of N is 3; the vertical projection surfaces of the adjacent step surfaces of the N-level step surface partially overlap; the N-level step surface The second moving platform that moves along the Y-axis direction is provided on each step surface of the surface and the diaphragm table; the optical unit includes N optical mirror groups that are respectively arranged on the second moving platform of the corresponding step surface, and the diaphragm is arranged on the optical Place the mesa on the second mobile platform.

Description

technical field [0001] The invention relates to optical instrument mirror group switching equipment, in particular to a trapezoidal mirror group array, which can be widely used in the development of optical detection and optical testing instruments and equipment. Background technique [0002] With the demand for multi-spectral and multi-functional fast switching of optical instruments and equipment, the design technology of analog star point target array or filter wheel is also being iteratively upgraded. [0003] At home and abroad, rotating structures are often used to switch mirror groups, such as the most common filter wheel mechanism. Generally, a disc-shaped structure is used, the drive shaft is used as the center of rotation, and the filter or target lens is embedded on the disc structure, and the target lens is driven by a motor to a certain position. This structure is simple and easy to operate, and is widely used. [0004] However, when the number of lens groups i...
