Claim Text:
1. A method for illuminating a sample in a microscope, the method comprising: illuminating the sample by a transmitted light bright field illumination from a white light LED source, or an incident light fluorescence illumination transmitted from an incident light source; providing a shutter positioned in a transmitted light bright field illumination beam path coming from the white light LED source; positively activating a shutter in the path of the transmitted light bright field illumination when the white light LED source is switched off and the incident light source is activated, thereby preventing light of the incident light source reaching the white light LED; and positively deactivating the shutter upon activating the white light LED source, wherein activating the shutter introduces the shutter into the path of the transmitted light bright field illumination, and deactivating the shutter removes the shutter from the path.
