Abstract
A device for sharp-edge uniform illumination of an observation field lying in a preselectable plane is adapted to utilize light from a remote source, via a flexible fiber-optic connection having a glass-rod termination for producing a uniformly illuminated light-exit surface. The glass rod is insertably connected to the device via clamping mechanism (9, 10) in such manner that its light-radiating surface is immediately adjacent to a diaphragm (7). In front of the diaphragm (7), a collector (2, 3) is fixedly positioned, to focus the diaphragm as a real image in the observation plane. The diaphragm (7) (together with the glass rod) is displaceable axially with respect to the collector (2, 3), thus enabling sharp adjustment for different distances from the observation plane.
