Abstract
An optical arrangement in the beam path of a light source suitable for fluorescence excitation, preferably in the beam path of a confocal laser scanning microscope, with at least one spectrally selective element ( ) to inject the excitation light ( ) of at least one light source ( ) in the microscope and to extract the excitation light ( ) scattered and reflected on the object ( ) or the excitation wavelength from the light ( ) coming from the object ( ) through the detection beam path ( ) is characterized for variable configurations with the simplest construction in that excitation light ( ) of different wavelengths can be extracted by the spectrally selective element ( ). Alternatively, an optical arrangement like this is characterized in that the spectrally selective element ( ) can be adjusted to the excitation wavelength to be extracted.
