Abstract: An assembly (100) 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 (10) for producing a beam of unpolarized light, preferably unpolarized monochromatic light, a useful light region (50) through which the unpolarized light passes and preferably passes through in a straight line from the light source (10) as well as an absorption device (30) arranged downstream of the useful light region (50) and preferably downstream in the direction of the direct beam radiation for at least partly absorbing impinging light, wherein the absorption device (30) comprises at least one polarization device (31, 32) arranged in the direction of the light beam.

Abstract: A device and a method for detecting scattered light signals is specified. A light source exposes a scattered light area in which particles may be present to light. With the objective of reducing costs and improving detection accuracy, the device comprises a plurality of optical sensors for detecting scattered light and an evaluation unit for evaluating the signals detected by the optical sensors, wherein the sensors are each arranged at a sensor angle relative to the incident axis of the incident light so as to detect scattered light from the scattered light area, wherein one of the plurality of optical sensors is a reference sensor, and wherein the evaluation unit is designed to relate the signal profiles of the other optical sensors to the signal profile of the reference sensor, wherein the signal profiles of the optical sensors serve in classifying any particles which may be present in the scattered light area.
