The invention discloses a lens eccentricity measuring device which comprises a workbench, a to-be-measured assembly, a standard assembly and a measuring assembly. The to-be-measured assembly, the standard assembly and the measuring assembly are all arranged on the workbench, a measured lens is arranged on the to-be-measured assembly, the measuring assembly detects the measured lens on the measuring assembly through the standard assembly, a controller is arranged on the workbench, and the controller is connected with the to-be-measured assembly. The to-be-measured assembly, the standard assembly and the measuring assembly are electrically connected with the controller. According to the invention, simulation diagram demonstration can be provided for lens eccentricity / air interval conditions in lens groups of the tested lens and among the lens groups, so that the distribution condition of a single group in the lens groups can be visually seen, and accurate eccentricity data and eccentricity data relative to different evaluation criteria can be provided; therefore, effective help is provided for analysis of reasons of problems in production of optical production enterprises, countermeasures can be developed for real problems, the efficiency is improved, and the cost is saved.
Description
technical field [0001] The present invention relates to the technical field of optical lenses, and more particularly, the present invention relates to a lens eccentricity measuring device and method. Background technique [0002] With the development of the optical industry, there are higher requirements for the image clarity, object image similarity, and deformation degree formed by the optical system. For the improvement of imaging requirements, it is necessary to put forward the stability of the lens in production. higher requirements. At present, the domestic optical industry cannot intuitively see the distribution of individual groups in the lens group, and thus cannot provide accurate eccentricity data and its eccentricity data relative to different evaluation benchmarks. Therefore, it is necessary to propose a lens eccentricity measuring device and method to at least partially solve the problems existing in the prior art. SUMMARY OF THE INVENTION [0003] A series...
