Abstract: A light source is provided that includes at least two semiconductor light-emitting elements that emit light of different color, a light guide, an electronic control unit, and a light sensor. The light emitted by the elements is injected, at least partially, into the light guide and exits laterally from the light guide. The brightness of the elements can be adjusted by the electronic control unit. The light sensor is arranged to receive the light injected by the elements and laterally exiting from the light guide. The electronic control unit accumulates sensor signals from the light sensor over an integration time interval and compares the accumulated signals with a target value or range to determine a difference, changes a brightness of the elements in response to the difference, and changes the integration time interval in response to the difference or to a change in the target value.

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: The disclosure relates to diagnostic, surgical, and/or therapeutic devices for being introduced into the human or animal body or for in vitro examination of human or animal blood samples or other body cells, in particular to an endoscope or a disposable endoscope that includes at least one illumination light guide and/or image guide for transmitting electromagnetic radiation, the illumination light guide or image guide having a proximal end face for incoupling or outcoupling of electromagnetic radiation and a distal end face for incoupling or outcoupling of electromagnetic radiation. The proximal and/or distal end faces consist of plastic elements that are transparent at least partially or in sections thereof, the transparent plastic being biocompatible and/or having non-toxic properties to human or animal cell cultures for exposure durations of less than one day. This allows for the production of assemblies for disposable endoscopes, inter alia.

Abstract: A light guide is provided that includes a fiber bundle, a jacket, a proximal end, a distal end, and a terminated end face. The fiber bundle has a plurality of optical fibers. The jacket encloses at least a part of the plurality of optical fibers and/or the fiber bundle. The jacket has a maximum outer lateral dimension that is greater than a maximum outer lateral dimension of the fiber bundle by at most 500 μm. The terminated end face is on the proximal end and/or the distal end. The terminated end face has a maximum lateral outer dimension that is not larger than the maximum outer lateral dimension of the jacket.
