Abstract
An illumination system for producing an illumination pattern for measuring the cornea of an eye and, in particular, for determining the topography thereof and in so doing facilitating distance-independent measurements. The illumination system according to the invention for determining the topography of the cornea of an eye includes an illumination unit and a unit for producing an illumination pattern, wherein the illumination unit includes a plurality of illumination modules. A lens array which produces a spatially distributed, collimated illumination pattern is used as a unit for producing an illumination pattern. The illumination system produces an illumination pattern, by which the topography of the cornea of an eye can be determined. Here, the illumination system is designed as a compact module, and so it can be easily combined with other measurement systems, without colliding with the beam paths thereof.
