  • Variable field angle and test pattern spatial frequency system for testing a lens
    Patent number: 6437857
    Abstract: A variable field angle and test patern spatial frequency optical assemblage for testing a lens having a plurality of field angles employs an improved modulation transfer function (MTF) design system for evaluating image quality produced by the lens being tested. A reflecting surface capable of translational and rotational movements is arranged along a predetermined optical path for receiving a collimated array of light rays and then directing the collimated array of light rays to the lens being tested.
    Type: Grant
