The invention relates to a lighting device by means of which a surface can be particularly uniformly illuminated, in particular for scientific or quality control purposes. In particular, the invention relates to a lighting device for homogeneously illuminating an object, which device comprises a homogenisation device (10) and is suitable for connection to a light source, said homogenisation device (10) having an inlet opening (12), an inlet chamber (16) arranged behind the inlet opening (12), an intermediate chamber (18), an outlet chamber (20), and an outlet opening (22) arranged behind the outlet chamber (20), wherein the inlet chamber (16), the intermediate chamber (18) and the outlet chamber (20) each have an outer surface (26) and an inner surface (24), wherein the inlet chamber (16) extends along a first main axis (H1) and the outlet chamber (20) extends along a second main axis (H2), and a light source arranged in the region of the inlet opening (12) can send light through the inlet chamber (16), the intermediate chamber (18), the outlet chamber (20) and the outlet opening (22) onto an object to be illuminated, characterised in that a beam of light cannot travel in a straight line from a point of the inlet opening (12) to a point of the outlet opening (22), and that at least the respective inner surfaces (24) of the inlet chamber (16), the intermediate chamber (18) and the outlet chamber (20) are diffusely reflective in at least one respective first region, such that a beam of light reflected on one of these inner surfaces (24), said beam illuminating a first reference surface (R1) with a first irradiance when incident, when emergent illuminates a second reference surface (R2) of the same size with a second irradiance that is lower than the first irradiance by at least a factor of 3, when both reference surfaces (R1, R2) are positioned at a distance of 10 mm from the reflection point (P). |
