Abstract:
A laser scanning microscope, comprising:a laser light source for illuminating a specimen and defining an illumination beam path; a detector for detecting the light returning from the specimen and defining a detection beam path; markers attached to at least to parts of the specimen wherein the markers can be excited to emit light, wherein the laser light source emits exciting light substantially at one wavelength; an optical component positioned in the illumination beam path and the detection beam path and configured as an acousto-optic beam splitter, wherein the optical component reflects the exciting light arriving from the laser light source toward the specimen and allows light of a different wavelength to be transmitted toward the detector; wherein different markers simultaneously emit light of different wavelengths when irradiated with exciting light of substantially the same wavelength; and, wherein the detector is a multi-band detector for the simultaneous detection of light at several wavelengths.
