Method for producing light beams of different wavelength or having different wavebands, and a photometer

摘要

Method for producing light beams of different wavelengths from the light of a light source (1), in which method the light of the light source (1) is guided to an intereference filter (3), which passes light (7) of a specific wavelength or of a specific waveband and reflects the remaining light. The reflected light is fed to a further interference filter (7) of identical design, which passes light of a different wavelength or of a different waveband and reflects the remaining light, so that it can be fed if necessary to a downstream interference filter (23). <IMAGE>
