Claim 19:
20. A measurement arrangement for capturing an absolute reflection spectrum of a sample; comprising:
a measurement light source, wherein the measurement light source includes:
a solid block, in which an illumination space, a light shaping space, and a light exit space are each formed as a cavity in the block and have a diffusely reflective inner surface; wherein the illumination space opens into the light shaping space; wherein the light shaping space opens into the light exit space; wherein at least one light source for generating light is at least partially arranged in the illumination space; wherein the light exit space has a light exit; wherein an axis of the illumination space and an axis of the light exit space are arranged at a distance from one another; and wherein the light shaping space is designed for a reversal of a light propagation direction; wherein light is able to emerge from the light exit space through the light exit to an outside of the block, the light emerging from the light exit forms measurement light generated by the measurement light source;

an optical receiver for receiving measurement light, which is arranged opposite the measurement light source;
a first mirror, which is arranged on an axis of the light exit and is aligned to reflect the measurement light emerging from the light exit; and
a second mirror, which is arranged on an axis of the optical receiver and is aligned toward the optical receiver for reflecting reflected measurement light.
