  • METHOD FOR PROVIDING AN IMAGE REPRESENTATION BY MEANS OF A SURGICAL MICROSCOPE, AND SURGICAL MICROSCOPE
    Publication number: 20220318969
    Abstract: A method for providing an image representation with a surgical microscope, includes capturing a color image representation of a capture region with a camera, capturing a fluorescence image representation of the capture region with a fluorescence camera, generating a detailed image from the captured color image representation with a spatial filter and an edge stop function, mixing the captured color image representation, the captured fluorescence image representation and the generated detailed image to form a mixed image representation, and providing an image signal which encodes the mixed image representation. Further, the disclosure relates to a surgical microscope.

  • Optical filter system and fluorescence observation system
    Patent number: 9958392
    Abstract: An optical filter system for florescence observation comprises an illumination light filter (I) and an observation light filter (O). The observation light filter has plural transmitting regions (D1O,D2O) allowing fluorescent light to traverse the observation light filter. Blocking regions (S0O,S1O) separate the transmitting regions. The illumination light filter has transmitting regions (D0I,D1I) where the observation light filter has a corresponding blocking region. The illumination light filter has blocking regions (S1I,S2I) where the observation light filter has a corresponding transmitting region. The plural transmitting regions of the illumination light filter hallow for an improved color impression in the normal light observation.
