SPECTRAL DETECTOR OR LASER SCANNING MICROSCOPE HAVING VARIABLE FILTRATION USING SPATIAL COLOR SEPARATION

摘要

The invention relates to a laser scanning microscope or spectral detector, having a detection beam path and at least one first imaging optics (2, 5), which images spectrally dispersed sample light in a Fourier plane such that in said plane the individual spectral components of the sample light are spatially separated from one another, that in said plane a micro-mirror array (4) is provided, and that by actuating the micro-mirrors a spectrally selective change in direction of the detection radiation takes place, wherein a part of the useful light of the detection radiation reaches a detector. In order to improve the spectral selection, either at least one second micro-mirror array (15) is provided, and 1:1 imaging of the first micro-mirror array in the second micro-mirror array is provided, or the same micro-mirror array is passed through at least twice, wherein in the light path between the first and second passes, a spatial offset of the light radiation of at least the first and second passes is generated on the micro-mirror array by optical means.
