Abstract
The invention relates to a light source comprising a microstructured optical element (11) that receives and spectrally spreads the light from a primary light source (3). The inventive light source is characterized in that the spectrally spread light penetrates at least one other microstructured optical element (15, 19, 21). Said light source can be efficiently used in scanning microscopy and especially in STED microscopy.
Claims20
A method for generating illuminating light, comprising:
- generating spectrally spread light with the aid of a light source, the light source comprising:
- a first microstructured optical element that receives and spectrally spreads the light from a primary light source;
- and at least one further microstructured optical element that receives the spectrally spread light from the first microstructured optical element and further spreads the spectrally spread light
- selecting at least one illuminating light wavelength and/or at least one illuminating light wavelength region from the further spectrally spread light, and
- splitting off the illuminating light of the at least one illuminating light wavelength and/or of the at least one illuminating light wavelength region from the further spectrally spread light.
