Patent ID: 8049873

Claim:
A surgical microscopy system having an optical coherence tomography (OCT) facility, the system comprising: microscopy optics providing a microscopy beam path and configured to image an object region onto an image plane disposed in the microscopy beam path, the microscopy optics comprising an objective lens; and an OCT system comprising: an OCT-measuring light source, a reflector, imaging optics, and a beam scanner having a first deflecting surface, wherein the OCT system provides an OCT beam path extending between the OCT-measuring light source and the object region; wherein the reflector is disposed in the OCT beam path between the imaging optics and the object region, and wherein the imaging optics are disposed in the OCT beam path between the beam scanner and the object region and configured to image a first plane disposed at a distance from the first deflecting surface of the beam scanner measured along the OCT beam path onto a second plane disposed at a center of the reflector, wherein the beam scanner is disposed in the OCT beam path and outside the microscopy beam path between the OCT-measuring light source and the object region, wherein the objective lens is disposed in the OCT beam path and the microscopy beam path between the reflector and the object region, and wherein the following relations hold: d 1 =A/β 2 and 0 mm≦ A≦ 200 mm, wherein d 1 is the distance between the first plane and the first deflecting surface of the beam scanner measured along the OCT beam path and β is a magnification of the imaging optics.
