Video microscope

A video microscope, comprising:

• a stage for receiving a specimen;
• a first light guide for a transmission method;
• a first polarizer, positioned below said stage, for partially polarizing light in the first light guide from a first light source;
• a second light guide for a reflection method;
• a second polarizer for partially polarizing light in the second light guide from a second light source;
• a lens assembly for emitting the polarized light from the first or second polarizer, said lens assembly comprising:
• an outer cylinder,
• a rotatable cylinder rotatably fitted to the outer cylinder,
• an analyzer,
• a compensating plate,
• a holder, mounted on the rotatable cylinder, for holding the analyzer and the compensating plate, the analyzer being rotated in accordance with the rotation of the rotatable cylinder,
• a beam splitter case at a lower end of the outer cylinder, and having an internally threaded hollow hole for the second light guide,
• an objective mounted on a lower part of the beam splitter case, and
• a beam splitter, positioned in the beam splitter case, for reflecting the polarized light from the second polarizer to the objective;
• a CCD mount comprising a CCD mounted on the lens assembly;
• and
• means for adjusting the height and focus of said lens assembly.
