More Information
Summary:An illumination device for a spectral optical measurement device includes arranged with respect to an optical axis of the illumination device which, during a measurement operation, extends along a normal to a center point of an area of a sample to be illuminated. One or more segments of a mirror in a shape of a ring are centered on the optical axis. The mirror has an internal reflective surface arranged such that, during the measurement operation, the internal reflective surface receives light emitted from the light source and reflects the light over the area of the sample to be illuminated. The internal reflective surface has a freeform shape in a cross-section through the internal reflective surface in a plane parallel to the optical axis (for example in which the optical axis lies), and, in a cross-section of the mirror in a plane perpendicular to the optical axis, the internal reflective surface is represented by a straight line.
