Method and system for controlling photo-curing deformation of doublet lens

The invention discloses a light curing deformation control method and system for a doublet lens, and the method employs an electric variable aperture diaphragm to control the ultraviolet light curing process of the doublet lens, carries out the gradual curing from the center of the lens to the periphery of the lens, and improves the light curing deformation of the doublet lens compared with a full-aperture curing method in which the whole lens group is irradiated by ultraviolet light at the same time. The curing method provided by the invention can reduce lens deformation caused by curing stress, and has important significance for improving the optical performance of the optical lens. 本发明公开了一种双胶合透镜光固化变形控制方法及系统，利用电动可变口径光阑控制双胶合透镜紫外光固化过程，进行从透镜中心向外围的渐进固化，相较于紫外光同时照射整个透镜组的全口径固化方法，本发明提出的固化方法可减小由于固化应力导致的透镜变形，对提高光学透镜光学性能具有重要意义。
