Abstract
A surgical fluorescence stereomicroscope (1) for detecting and operating on fluorescing areas of an object field (7) is described, which microscope encompasses a first illumination device (2) for irradiating the object field (7) with light in an excitation wavelength region (E). The surgical fluorescence stereomicroscope (1) further encompasses an observation beam path (21) for guiding the reflected and emitted light received from the object field (7), and a first observation filter (9) in the observation beam path (21) which is transparent in the excitation wavelength region (E) and in a fluorescence wavelength region (F). According to the present invention, means (10a to 10c) for controllable attenuation in the excitation wavelength region (E) are additionally arranged in the observation beam path.
