Optical arrangement with spectrally selective element for use in the beam path of a light source suitable for stimulation of fluorescence, pref. a confocal laser-scanning microscope

摘要

The arrangement has at least one spectrally selective element (4) for coupling the stimulation light from at least one light source (2) into the microscope and for stopping the stimulation light reflected and scattered at the object (10) and the stimulation wavelengths from the light passing from the object over the detection beam path (12). Stimulation light of different wavelengths can be stopped by the spectrally selective element.
