Abstract:
An optical arrangement in a beam path of a laser scanning microscope, said microscope having a light source, at least one adjustable spectrally selective element adjustable to the wavelength of excitation light from said light source for coupling in said excitation light from said light source into said microscope and at least partially blocking said excitation light scattered and reflected at an object from said beam path while transmitting detection light coming from said object on said beam path, wherein said optical arrangement comprises:an optical component after said at least one adjustable spectrally selective element in said beam path for dispersion and/or birefringence of said detection light; at least one detector after said optical component in said beam path for receiving at least a portion of said dispersed and/or doubly refracted detection light, and at least one beam diverter for directing the at least a portion of said dispersed and/or doubly refracted detection light to said at least one detector.
