An optical light diffuser providing a generally cylindrical pattern of light emission. The diffuser is formed from an optical fiber operable to transmit the optical radiation from its proximal end to its distal end and having a guiding core and a cladding surrounding the core. The optical fiber has an abraded section at its distal end that allows light to escape uniformly over the abraded section forming a generally cylindrical pattern of diffuse light that surrounds the distal end of the optical fiber.
L'invention concerne un diffuseur optique émettant un motif lumineux généralement cylindrique. Ce diffuseur est formé à partir d'une fibre optique pouvant transmettre un rayonnement optique de son extrémité proximale à son extrémité distale et présentant un coeur de guidage et une gaine enveloppant ce dernier. La fibre optique présente une partie abrasée à son extrémité distale, qui permet à la lumière de sortir uniformément sur la partie abrasée en formant un motif généralement cylindrique de lumière diffuse qui entoure l'extrémité distale de la fibre optique.
