Abstract: An illumination system for a medical technology therapy and/or diagnosis system is provided. The system includes a light source, preferably a laser light source, and a light guide, which at a proximal end can be connected to the at least one light source and/or can be assigned thereto, and which system has at the distal end of the light guide a diffuser element having a longitudinal axis which extends into or in the diffuser element perpendicularly with respect to an input face of the light guide, wherein the diffuser element emits light laterally with respect to the longitudinal axis over its active length in the operating state, wherein the diffuser element has at least one diffuser base body and the diffuser base body contains a matrix that has at least one scattering element and is enclosed at least on its cladding surface by a solid encapsulation.

Abstract: An endoscope is provided that has a first component having an LED that emits light and a second component having a proximal end, a distal end, an image capturing element, and a light guide. The proximal end is coupled to the first component. The image capturing element being arranged at the distal end. The light guide comprising an optical fiber extending through the second component. The LED is coupled to the proximal end such that the light is injected into the optical fiber and is conducted from the LED at the proximal end to the distal end and to emit the light at the distal end. The optical fiber has a cross section of at least 80 μm and has a polymer-based coating or a protective sheathing made of a polymer-based tube material arranged on an outer surface.

Abstract: An endoscope is provided that includes a first component, a second component, a light source, an image capturing element, and a light guide. The second component has a proximal end and a distal end with proximal end coupled to the first component. The light source is integrated in the first component and includes a laser and a converter. The laser emits primary light and the converter converts the primary light at least partially into secondary light that has a different wavelength. The image capturing element is arranged at the distal end. The light guide has an optical fiber that extends through the second component. The converter is coupled to the proximal end such that the primary and secondary light is injected into the optical fiber, is conducted from the proximal end to the distal end, and emitted at the distal end.

Abstract: An illumination system for medical therapeutic and/or diagnostic system is provided. The illumination system includes a laser light source and a light guide. The light guide has a proximal end that is connectable and/or assignable to the one laser light source. The light guide has a distal end with a diffuser element having a radial, spherical emission characteristic. The diffuser element includes a diffuser main body made of an inorganic material, in particular a glass, a glass ceramic, a glass-like substance or a composite substance of the aforementioned substances. The diffuser main body has a scattering element and has a surface that is pore-free and smooth.

Abstract: A fiber-optic light guide is provided. The light guide includes plurality of optical fibers and an enveloping material. The plurality of optical fibers define a flexible fiber bundle. The flexible fiber bundle has a first diameter and a length along a longitudinal axis. The enveloping material encloses the plurality of optical fibers at one end of the flexible fiber bundle and over at least a part of the length to define a rigid portion. The plurality of optical fibers in the rigid portion are fused with one another. The flexible fiber bundle has a modified or formed cross-sectional geometry in a region of the enveloping material.
