MICROSCOPE FOR OBSERVING A SAMPLE IN THE BRIGHT FIELD ILLUMINATION BY TRANSMITTED LIGHT OR IN FLUORESCENCE-CONTRAST EPI-ILLUMINATION
First Claim
1. A microscope, designed for observing an object selectably in bright-field transmitted light contrast or in incident-light fluorescence contrast, in which a microscope beam path is directed from a bright-field light source through the object and a microscope objective into a microscope tube, comprising:
- a fluorescence unit including a fluorescence excitation light source, an illumination optical system,a filter set comprising at least one excitation filter, at least one emission filter, and a beamsplitter;
wherein the fluorescence unit is mounted so that it is movable, such thatin a first end position of movement the beamsplitter and the emission filter are outside the imaging beam path of the microscope and in a second end position of movement the beamsplitter and the emission filter are in the imaging beam path between the microscope objective and the microscope tube.

Abstract
A microscope for observing an object selectably using the bright-field transmitted light contrast procedure or the incident-light fluorescence contrast procedure. During the bright-field transmitted light contrast procedure, an illumination beam path is directed from a bright-field light source to the object and an imaging beam path is directed from the object through the microscope objective into the microscope tube, which includes a fluorescence unit that includes a fluorescence excitation light source, an illumination optical system, a filter set having at least one excitation filter and at least one emission filter, as well as a beamsplitter. The fluorescence unit is mounted movably, so that in a first end position of movement the beamsplitter and the emission filter are out of the imaging beam path of the microscope and in a second end position of movement they are in the imaging beam path between the microscope objective and the microscope tube.

14. A microscope, designed for observing an object selectably in bright-field transmitted light contrast or in incident-light fluorescence contrast, in which, during observation in bright-field transmitted light contrast a microscope beam path is directed from a bright-field light source through the object and a microscope objective into a microscope tube, comprising:
-
a fluorescence unit including a fluorescence excitation light source, an illumination optical system, a filter set comprising at least one excitation filter and at least one emission filter and a beamsplitter; wherein the fluorescence unit, the beamsplitter and the emission filter are mounted so as to be movable, such that in a first end position of movement the beamsplitter and the emission filter are outside the imaging beam path of the microscope and in a second end position of movement the beamsplitter and the emission filter are in the imaging beam path between the microscope objective and the microscope tube.
