Abstract

The invention relates to an optical measuring stand apparatus. A stand structure comprises an uniform illumination system, a panel support structure, a lower layer support framework, a displacement bench and a movable air floating pedestal from top to bottom. By using the stand apparatus, a problem that structures of detection systems of a Shark-Hartmann sensor, a double-grating shearing interference and the like are difficult to adjust is solved. An adjusting stroke of a certain range is possessed and lens groups with different focal lengths are compatible. A center of the stand apparatus is provided with a large installing hole. Through an adapter flange, lens with different diameters are compatible. And design layout is open, which is convenient for dismounting and integration installation.

Description

technical field [0001] The invention belongs to the technical fields of detection of optical element / system performance parameters, detection of light source performance parameters, etc., and specifically relates to the detection of optical performance parameters of a lens system and the detection of performance parameters of an accompanying detection light source, and is particularly suitable for detection of performance parameters of lens groups. Background technique [0002] The more traditional optical measurement method is to use optical components with mechanical structures, and the results are obtained by visual observation by testers. There are large errors in data observation, data analysis, and calculation processes. Due to the rapid development of computer technology in recent years, as well as the great progress of semiconductor photoelectric conversion sensors and image acquisition devices such as CCD and CMOS. Optical measurement has entered a stage based on im...
