Abstract

The swing mechanism includes mirror base, bracing frame. The bracing frame is composed of a support rack, left and right swing frames setup with same structure at two side of the support rack. The left swing frame includes two pillars, up sheet support, and low sheet support. Through two pillars, outer sides of the up and low sheet supports are connected to each other fixedly. Through up and low two bearings, the side near to the support rack connected to middle upright post. Being matched to outline size of mirror base, hole of mirror base is made in middle of the up and low sheet supports. Elastic fastening parts are setup on the up sheet support, and low sheet support. Hole of mirror base is in use for mirror base to be placed. Banking screw is setup on left and right swing frames. The invention is suitable to setting up dual optical flat in large aperture. Position control is carried out in direction perpendicular to swing plane. Features are: simple structure and compact.

Description

technical field

[0001] The invention relates to a precision optical adjustment device for an optical instrument, in particular to a double optical plate swing mechanism, especially a swing mechanism suitable for adjusting the position of a large diameter double optical plate in the vertical direction of its swing plane. Background technique

[0002] Optical flat plates include optical parallel flat plates and optical wedge flat plates. The double optical flat plates formed by two groups of optical flat plates are used as compensators and micrometers in optical instruments. The angle change of the double optical flat panel during use is realized by the swing mechanism, and the performance of the swing mechanism determines the use effect of the double optical flat panel.

[0003] The prior art [1] (the editing group of "Optical Instrument Design Manual". Optical Instrument Design Manual. National Defense Industry Press, Beijing, 1971, P.97) provides a double optical flat plate...
