ABSTRACT:
A method for separating different emission wavelengths in a scanning microscope includes scanning a specimen with an illuminating light beam by passing the illuminating light beam over the specimen using a beam deflector, and selectively applying each of a plurality of excitation wavelengths to the illuminating light beam during the scanning according to a predefinable illumination scheme. Emission light coming from the specimen is detected using a detector, the emission light including emission wavelengths corresponding to the excitation wavelengths. The detector is read out when an excitation wavelength is applied so as to provide detected signals. The detected signals are associated with the respective excitation wavelengths using the illumination scheme.
