A lens inspection device and method are provided. The lens inspection
method includes the steps of providing a collimating light beam,
polarizing the collimating light beam by a polarizer to produce a
polarized light beam, deflecting the polarized light beam by a lens to be
measured to produce a deflected light beam, providing a phase retardation
plate through which a polarized compensation image is generated, and
comparing the polarized compensation image with a lookup table having
standard color values of a plurality of standard polarization compensated
images recorded therein, so as to determine whether a deformation is
presented on the lens.
