FIELD: physics.
SUBSTANCE: in order to realize reliable attenuation, in particular directly incident light, it is provided that the solution according to the invention comprises light source (10) for an unpolarized light beam generating, preferably unpolarized monochromatic light, useful light area (50) through which unpolarized light passes and preferably extends in a straight line from light source (10), as well as upstream absorption device (30) downstream of the useful light zone (50), and preferably downstream in directional beam direction, for at least partial absorption of the incident light, absorption device (30) comprising at least one polarization device (31, 32) arranged in the direction of the light beam.
EFFECT: device (100) is proposed for attenuation of an incident light beam with finite expansion.
