Patent ID: 11796782

Abstract:
An optics arrangement for flexible multi-color illumination for a light microscope includes an acousto-optical tunable filter (“AOTF”). The AOTF is set up to diffract two light components from incident illumination light into different order-of-diffraction directions. The two light components differ in their wavelengths and polarizations. Alternatively, an electro-optical modulator (“EOM”) can be used, with which two temporally successive light components of different wavelengths are set to different polarization directions. A polarization beam splitter separates the two light components of different wavelengths and polarizations into reflection light, which is reflected at the polarization beam splitter, and transmission light, which is transmitted at the polarization beam splitter. A light structuring apparatus imprints different structures onto the transmission light and the reflection light. The structured transmission light and the structured reflection light are then recombined by the polarization beam splitter or a further polarization beam splitter onto a common beam path.
