Patent ID: 8503084

Claim:
Optical arrangement for use as at least one of a main beam splitter and a beam combiner of a microscope, comprising: an optically dispersive medium chromatically dispersing a coupled in polychromatic light beam in space; at least one controllable microstructured element that is provided downstream of the optically dispersive medium and comprises a DMD (Digital Micromirror Device) having an array of segments, allowing to switch the beam paths within the optical arrangement, resulting in at least one of controlling and influencing of one or more light beams that are coupled out; and an optically combining medium downstream of the controllable microstructured element combining chromatically dispersed light reflected by the DMD into the optically combining medium; wherein the optical arrangement is configured to couple one or more light beams into the arrangement, modify at least one of the one or more light beams by reflecting after chromatic dispersion in space parts of the one or more light beams by the controllable microstructured element into the optically combining medium, and coupling out at least one of the light beams that were coupled in after having passed through the optical combining medium; and microlenses are allocated to the segments of the microstructured elements for focussing the incident light onto these segments and increasing a fill factor for the coupled in light beam incident on the array of segments.
