  • Page 8: Measurement Principle

    Auto Lensmeter CLM-9000 Measurement Principle Basic Principle When there is no lens (0D state), parallel light that has transmitted the collimator lens passes the pinhole and makes image on CMOS. In case of convex lens (lens with plus diopter), parallel light that has transmitted the collimator lens converges through the measuring lens, passes the pinhole and then makes image on CMOS.
