Microscope with an optical filter identification unit

Microscope with provided in the illumination and / or observation and / or detection optical path optical components for different spectral influencing at least one of said beam paths, DOLLAR A, preferably outside of these beam paths, an arrangement of a multi-wavelength emitting light source and at least one spectral sensor is provided which detects the light of this light source after interaction with a device, the interaction being by transmission or reflection of the light by the device. DOLLAR A The detected values ​​of the spectral sensor are compared with pre-stored values ​​and there is advantageously an assignment to pre-stored values ​​in a memory, wherein the assignment takes place together with a position signal of a component changer.
