Abstract
A luminous unit () for an optical recording device () comprising a light source () for generating radiation and a partly reflective element, which is disposed downstream of the light source () in a main emission direction (H) and subdivides a space into a first half-space facing the light source () and a second half-space remote from the light source (), wherein the partly reflective element at least partly transmits the radiation coming from the light source () from the first half-space and at least partly reflects the external radiation coming from an opposite direction from the second half-space.
