Optical system and optical method and use of such a system or method for protecting an imaging sensor or for protecting the human eye from glare and / or damage from electromagnetic radiation

摘要

Optical system, which is designed to divide electromagnetic radiation (1) of a wavelength range (WB) incident thereon onto a plurality of spectrally separate wavelength bands (Wb ₁ to Wb ₈ ) as follows: In several spatially separated output beam paths (2a, 2b) of the optical system, one or more of the wavelength bands (Wb ₁ to Wb ₈ ) can be respectively generated by means of one or more optical multiband elements (s) of the optical system, that no wavelength band of one (2a) of the output beam paths (2a, 2b) does not overlap spectrally with any wavelength band of another (2b) of the output beam paths (2a, 2b).
