Spectrometer for measurement of light rays, has anti-aliasing-unit changing intensity of rays based on curve with values so that unit has regions with different intensity changes, where rays from unit enter into radiation input

摘要

The spectrometer has an optical anti-aliasing-unit (2), which is designed such that the intensity of light rays that occur by the unit along an integration line that stands perpendicular to the light rays is changed according to a preset transmission curve. The transmission curve has two transmission values, so that the optical anti-aliasing-unit possesses two regions with different intensity changes. The unit is arranged at a radiation input (1) of an imaging unit such that light rays from the unit enter into the radiation input.
