Abstract

A surgical microscope (100) has an illuminating module (120). The illuminating module contains an illuminating optic which images a field diaphragm (124) to a parallel illuminating beam path at infinity. The field diaphragm (124) is illuminated by a light source. The illuminating optic includes a first lens assembly and a second lens assembly which functions to image the field diaphragm (124) into the object region (108) via the microscope main objective (101) of the surgical microscope (100). An in-coupling element (128) is provided between the first lens assembly (125) and the second lens assembly (126) and this in-coupling element couples the OCT-scanning beam into the illuminating beam.
