Abstract:
1. A microscope comprising: a main objective; a pair of spaced observation beam paths passing through the main objective; a deflection element having a pair of spaced openings for the pair of observation beam paths and a planar deflection surface surrounding both of the pair of spaced observation beam paths; a light source; collimating optics after the light source for providing a collimated illumination beam traveling along an illumination axis; a stop radially adjustable relative to the illumination axis to selectively allow passage of a spatial portion of the collimated illumination beam and block passage of another spatial portion of the collimated illumination beam, the spatial portion of the collimated illumination beam that passes through the stop being deflected by the planar deflection surface to pass through the main objective and illuminate a specimen; wherein an angle at which the specimen is illuminated is adjusted without changing location of the deflection surface by adjusting the stop radially relative to the illumination axis.
