Abstract (en)
[origin: WO2007121705A1] The invention relates to a device for high-intensity uniform illumination with minimal light reflection for use in reflective-type microscopes. Said invention is characterised by a light source (1) with a uniform emission and the following components, arranged in succession in the emission direction: a lens combination (2) with a short focal length, said length f<SUB>1 </SUB>being adjusted in such a way that the light source is projected to infinity; a rectangular diaphragm aperture (3), which is located on the rear plane of said lens combination, the Fourier plane of the lens combination being situated on said plane; an additional lens (4) with a focal length f<SUB>2</SUB>, through which the rectangular diaphragm aperture (3) is projected onto the intermediate image plane (6) of the microscope; and a circular diaphragm (5), onto which the light source (1) is projected in sharp focus and which is located on the rear plane of said additional lens.
