ABSTRACT:
This invention relates to a confocal laser scanning transmission microscope including a deflecting element for deflecting a light beam at a set scanning frequency in a main scanning direction and an auxiliary scanning direction perpendicular to the main scanning direction to irradiate the light spot to a specimen, and the microscope further comprises an infinity compensating objective lens for collecting a transmitted light through the specimen to form into a parallel beam and a cube-corner-reflector disposed on the opposite side of the specimen across the objective lens and on the exit pupil position of the infinity compensating objective lens.
