Aspheric lens eccentricity detection device based on wavefront technology and its detection method

摘要

The present invention relates to an aspherical lens eccentricity detection device based on wavefront technology and a detection method therefor, comprising an upper optical fiber light source, an upper collimator objective lens, an upper light source beam splitter, an upper beam constriction front lens, an upper beam constriction rear lens, and an upper Imaging detector, upper imaging beam splitter, upper wavefront sensor, test lens holder device, lower light source beam splitter, lower beam constricted front lens, lower beam constricted rear lens, lower imaging beam splitter, lower wavefront sensor, lower imaging detector, lower collimator objective It includes a lens and a lower fiber optic light source. The present invention is a non-contact detection, there is no risk of damage to the lens, there is no moving member in the device, and the reliability and stability of the system are high. Since the present invention can detect a plurality of eccentricity errors within the effective aperture of the aspherical lens at once, errors due to stitching detection can be avoided, and the detection time can be greatly shortened, and can be used for on-line detection of assembly lines.
