Abstract

The main objective of the microscope is shifted from the stereoscopic viewing position to a position in which its optic axis coincides with the optic axis of one of the twin variable magnification optical systems used for stereoscopic viewing. This shifted position provides better resolution for photography and measurement and reduces the correction requirements on the main objective. The shift of the objective is coordinated with a shift of the object under observation or a countershift of the upper part of the microscope in order to maintain the same field of view of the object.
