Spectrally detector with a variable filtering by spatial color separation and laser - scanning - microscope

摘要

Laser - scanning - microscope or spectrally detector, with a detection beam path and at least one first optical imaging system, the spectrally dispersed sample light in a fourier - plane images in such a way that, in this the individual spectral components of the samples light are spatially separated from one another, in this plane, a micro-mirror array is provided, and by controlling the micromirrors a spectrally selective change in the direction of the detection of radiation, wherein a utility, namely a part of the detection of radiation passes to a detector,where to improve the spectral selection of either at least a second array is provided, and a 1: 1 image of the first array is provided in the second arrayor the same array is passed through at least twice, wherein in the light path between the first and second pass by optical means comprises a spatial displacement of the light radiation of at least the first and second passage is produced on the micro-mirror array.
