Emitting light part and receiving light part also built optical system for UV measurement. One is composed of UV lamp and the other receives UV light. The wavelength of the UV light is 395nm.

  • Page 10: Measurement Principle

    Auto Lensmeter HLM-7000 Measurement 1.6. 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 CCD. 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 CCD.
