Abstract
An arrangement for switching the operating modes of a microscope tube between the observation position, photo position and simultaneous observation/photo position. A prism is used having surfaces of different transparency which can be moved selectively into the beam path.
Claims6
An arrangement for switching the operating modes of a microscope tube between the observation position, the recording position and the simultaneous observation and recording position, comprising:
- a first prism;
- a second prism that is cemented to the first prism;
- said first prism having, on its side facing the second prism, surfaces of different transparency for the beam coming from the microscope objective;
- and
- at least one operating control being provided which can alternately move one of these surfaces of different transparency by shifting the prisms in two orthogonal directions into the beam path coming from the microscope objective;
- wherein the at least one operating control actuates between three different operating modes.
