A light source for a surgical microscope includes a laser light source, first and second scattering elements defining first and second planes, respectively, and a collector optical device arranged between the first and second scattering elements with a focal length and a focus in the first plane. The laser light is focused on a first beam cross section with a first dimension in the first plane. The scattered beam emanating from the first scattering element is imaged at infinity with a first numerical aperture and produces a second beam cross section with a second dimension in the second plane. The second scattering element emits a beam of illumination light with a second numerical aperture at each point of the beam cross section in the second plane. The illumination light emanating from the second scattering element forms an illuminated field imageable into an object plane by an illumination optical device.

An OCT system comprises an OCT scan module for retinal scanning and an add-on anterior segment scanning module which includes at least one anterior segment scan lens () and an add-on fixation target () which is used to maintain the viewing direction of the eye () under investigation while achieving anterior segment scanning. Because the anterior segment scan module added to the exterior of an existing OCT system for retinal scanning has an add-on fixation target (), it is possible to maintain the viewing direction of the eye () under investigation while carrying out anterior segment scanning without adjusting the internal beam path of the OCT system, and the OCT system of the present invention can be adapted to patients with only one functioning eye.
