Abstract
Known apparatuses for irradiating a substrate include a housing and, within the housing, a receptacle for the substrate having a circular irradiation surface and a first emitter for generating optical radiation having a first emitter tube arranged in a plane of curvature extending parallel to the irradiation surface and having an emitter tube end, whereby the receptacle and the first emitter can be moved with respect to each other. In these apparatuses, the irradiation surface includes first and second semi-circular surface portions. An improvement of the known apparatuses, which enables the substrate to have a rotationally symmetrical, homogeneous temperature distribution while keeping the complexity of design and control technology minimal, provides a first emitter tube having a curved illumination length section, extending with a mirror symmetrical-oval basic shape in the plane of curvature, wherein the first illumination length section is associated essentially with one of the semicircular surface portions.
