Abstract
An assembly () for attenuating the impinging light of a beam of radiation of finite expansion with the objective of realizing reliable attenuation particularly of directly impinging light comprises a light source () for producing a beam of unpolarized light, preferably unpolarized monochromatic light, a useful light region () through which the unpolarized light passes and preferably passes through in a straight line from the light source () as well as an absorption device () arranged downstream of the useful light region () and preferably downstream in the direction of the direct beam radiation for at least partly absorbing impinging light, wherein the absorption device () comprises at least one polarization device () arranged in the direction of the light beam.
