Abstract
A measuring light source includes a hollow body having a diffusely reflective inner surface. Formed in the hollow body are a concave, concave mirror-shaped illumination space, a tubular light shaping space, and a concave, concave mirror-shaped light exit space, which have a shared axis. A light source for generating light is at least partially situated in the illumination space. The light exit space has a light exit. The illumination space and the light exit space with their concave mirror shapes are situated opposite one another and are connected by the tubular light shaping space. A diffusely reflecting reflective disk for reflecting the light, reflected from the inner surface of the hollow body situated in the light exit space, through the light exit to outside the hollow body is situated in the hollow body.
