Abstract
A microscope includes a generally L-shaped motion box and an optical support located on a horizontal leg of the motion box. A binocular tube is fixed to the optical support. An objective changer is guided in the horizontal leg of the motion box and supports a first objective for stereoscopic observation and a second objective. The second objective is the objective of a conventional microscope. A beam splitter connected directly downstream of the second objective distributes the incident light into the two observation channels of the microscope. With this stereomicroscope, a single manipulation switches from normal stereoscopic observation to binocular observation with much greater magnification.
