A stereomicroscope has a left and a right stereo radiation path and an adjusting device for selecting a stereo base. A main lens is arranged between an object to be observed and the adjusting device, which may be designed as an opto-mechanical switching device. The arrangement allows an integrated structure with low light losses.

Stereomicroscope

The invention concerns a method and device for determining the direction of an object (,) which emits or reflects optical radiation. An optical element (,) which structures the wavefront of the radiation converts the conventional dot-type image (,) into an intensity distribution (,&prime;) with more than one maximum on a locally resolving opto-electronic detector (,). From the intensity distribution (,&prime;) and the structure function of the optical element (,), the direction of the object (,) can be determined with a high degree of accuracy over a wide measurement range. In addition, this gives a design with a shorter optical path length and very few optical components.

Method and device for determining the direction in which an object is located

An arrangement for determining the position of a surgical microscope uses signal transmitters and signal receivers. Light emitting diodes that emit coded light signals and light receptors for receiving the coded light signals are arranged in various locations in space. Reflectors having narrow-bond reflection characteristics are arranged on the microscope so that the light reflected can be identified.
