Abstract
Disclosed are an illumination device for an observation device comprising one, two or more observation beam paths with one respective beam of observation rays, especially for an ophthalamogic surgical microscope, and a corresponding observation device. Said illumination device is provided with at least one light source for generating at least one beam of observation rays in order to illuminate an object that is to be observed. According to one embodiment of the invention, at least two partial bundles of illumination rays are provided, each of which extends coaxial to a corresponding beam of observation rays, while the partial beams of illumination rays are embodied so as to form two or several illumination spots on the fundus of an object that is to be observed, e.g. an eye, said illumination spots having variable sizes, thus allowing the illumination beam to cooperate in a precisely defined manner with the observation beam paths, which makes it possible to meet especially the practical requirements regarding homogeneity of the red reflex.
