Abstract:
1. An optical measurement device for measuring an optical appearance of a surface of a sample of a human skin, wherein the surface is at least partly translucent, the optical measurement device comprising: an illumination device for illuminating the surface with an illumination beam wherein the illumination beam is generated from a radiation beam emitted from a radiation source; a detection device for intercepting a response beam generated as a response of the sample to the illumination beam, incident on the surface; a measuring head comprising a base plate that can be brought into contact with the surface of the sample, wherein the base plate comprises at least one elongated aperture, which is designed such that the response beam, generated below the surface in a sub-surface area of the sample, is detectable by the detection device, wherein the base plate is arrangable at the surface of the sample in order to perform a measurement of the optical appearance and the illumination beam directly reflected at the surface is cut off.
