20090257065 | SURGICAL MICROSCOPY SYSTEM HAVING AN OPTICAL COHERENCE TOMOGRAPHY FACILITY - A surgical microscopy system is provided wherein an optical coherence tomography facility is integrated into a microscopy system. A beam of measuring light formed by collimating optics of an OCT system is deflected by a beam scanner, traverses imaging optics, and is reflected by a reflector such that the beam of measuring light traverses an objective lens of microscopy optics and is directed to an object region of the microscopy optics. A position of the beam of measuring light being incident on the reflector is substantially independent on a direction into which the beam of measuring light is deflected by the beam scanner. When traveling through the beam scanner, the beam of measuring light is comprised of a bundle of substantially parallel light rays. | 10-15-2009 |
