1.6. Measurement Principle
Basic Principle
When there is no lens (0D state), parallel light that has transmitted the collimator lens passes the 4 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 4 pinhole and then makes image on CCD. On the other hand, in case of concave lens (lens with
minus diopter), parallel light that has transmitted the collimator lens diverges through the measuring lens and then passes the 4
pinhole and at last makes image on CCD.
