摘要:
The lens inspection system permits detecting scratches, extraneous objects, such as stains, and other kinds of defects of an optical member with high accuracy.
A light beam is projected from one side onto a lens to inspect, and a light transmitted and scattered through the lens is photo-electrically detected as a dark field image of the lens on the other side of the lens, and when the intensity of the photoelectric signal detected from an inspection range of a photoelectric imaging device goes above a preset level, the lens is judged to be defective.

透镜检查系统能够高精度地检测光学构件的划痕,异物等污渍等各种缺陷。 将光束从一侧投影到透镜上以检查,并且通过透镜透射和散射的光被光电检测为透镜的另一侧上的透镜的暗视场图像,并且当强度为 从光电成像装置的检查范围检测到的光电信号超过预设值,判断为有缺陷。
