    Auto Lensmeter HLM-9000 1.3. Cautions  Always protect this instrument with Dust Cover after using.  Do not vibrate or drop this instrument; it can cause damage.  Use soft cloth or cotton swaps with alcohol when clean the pinhole.
  • Page 9  Signal Receiving Part Hartmann plate : divide the signal into 81 points. Prevent the other light except the signal 2-dimentional CMOS sensor : converts signals into digital value. The lens meter also built optical system for UV and Blue light transmittance. The system is composed of light emitting LED (UV and Blue light) and receiving part (UV and Blue detector).

  • Page 10: Measurement Principle

    Auto Lensmeter HLM-9000 1.6. 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 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.
