ABSTRACT:
A CCD microscope includes: two polarized light illumination systems for irradiating polarized lights having vibrating directions in perpendicular to each other selectively to an object to be observed, and an analyser disposed on an optical path from the object to a CCD device for picking-up an image of the object, the analyser having a vibrating direction in parallel with the vibrating direction of the polarized light from one polarized light illumination system, and in perpendicular to the vibrating direction of the polarized light from the other polarized light illumination system. The surface state of the object is picked-up by a polarized light of one polarized light illumination system that is kept unchanged for the polarized state upon reflection on the surface, while the inner state of the object is picked-up by a polarized light of the other polarized light illumination system that is changed for the polarized state.
