Abstract:
1. A microscope system for observation of fluorescences of different fluorescent dyes in an object placeable in an object plane wherein the microscope system comprises an illumination system for illuminating the object placeable in the object plane with illumination radiation and an observation system for providing a first observation optical path for optically imaging the object placeable in the object plane, wherein the observation system further comprises at least one camera, wherein the observation radiation guided in the first observation optical path can be supplied to the camera, wherein the illumination system has a first operating state in which the illumination radiation has a spectrum which includes a first excitation band of a first fluorescent dye and, at the same time, is partly free from a second excitation band of a second fluorescent dye different from the first fluorescent dye, and wherein the observation system has a first operating state in which sections of the first observation optical path guide the observation radiation having a spectrum which includes a first fluorescence band of the first fluorescent dye, wherein the illumination system has at least a second operating state in which the illumination radiation has a spectrum which includes the second excitation band of the second fluorescent dye, the observation system comprises an infrared barrier filter supported by an infrared filter carrier, wherein the observation radiation guided by the first observation optical path can be supplied to the camera via the infrared barrier filter, the observation system has at least a second operating state in which sections of the first observation optical path guide the observation radiation having a spectrum which is partly free from the first fluorescence band of the first fluorescent dye, the infrared filter carrier has a first operating state in which the first observation optical path in front of the camera is free from the infrared barrier filter, and a second operating state in which the infrared barrier filter is arranged in front of the camera in the first observation optical path, and the microscope system further comprises a controller, wherein the controller is configured to selectively switch the illumination system as well as the observation system and the infrared filter carrier into the first operating state or to selectively switch the illumination system as well as the observation system and the infrared filter carrier into the second operating state.
