Abstract

The invention contemplates an improved microscope having a partially transmitting mirror in the observation light path, the mirror deflecting some of the illuminating light path onto a first object, while a second object is located in the light path which passes through the mirror. In one form, the reflected and transmitted light paths are designed symmetrically, and each includes one microscope objective; one of these objectives is adapted to be inclined with respect to the direction of the light beam, and a stop is so positioned in the system that the two separately observed objects appear simultaneously and side-by-side in the field of view of a single eyepiece.
