  • Cooling of reflective spatial light modulating devices
    Patent number: 7938543
    Abstract: An optical system as subject of the present invention comprises at least one packaged spatial light modulator comprising a front side for facing incident light. The optical system further comprises projection optics for projecting an image formed by the packaged spatial light modulator, there being a sealed gas space in between the front side of the packaged spatial light modulator. The optical system comprises a first heat transporting means being thermally coupled to the frontside of the packaged spatial light modulator, the first heat transporting means comprising a thermally conductive frame contacting the front side of the packaged spatial light modulator along an edge thereof. A second heat transporting means being thermally coupled to the package back side may be provided as well. The first and second heat transporting means are thermally separated by the package.
