    • The invention relates to an illumination unit comprising a high-power light source (1), a first optical element (12) for focussing the light emitted from the high-power light source (1), a photometric head (8) for the pre-determinable illumination of an object (3), an optical waveguide (2) for transmitting the emitted and focussed light to the photometric head (8), and a displacement unit (6) for varying the axial distance between the high-power light source (1) with the first optical element (12) and the inlet of the optical waveguide. The cross-sectional surface of the focal point is at least twice as large as the cross-sectional surface of the optical waveguide (2) on the light input side, and the intensity of the light coupled into the optical waveguide (2) can be varied by axial displacement of the high-power light source (1).
