Abstract: A drawn glass element for producing glass optical waveguides is provided. The element has two first length portions with a first cross-sectional area and which define the two ends of the glass element; a second, intermediate length portion between the two first length portions, which has a second cross-sectional area smaller than the first cross-sectional area; a first transition portion between the intermediate length portion and one of the first length portions; and a second transition portion between the intermediate length portion and another of the first length portions. The first and second transition portions have a cross-sectional area that steadily changes and merges from the first cross-sectional area into the second cross-sectional area.

Abstract: LED lighting devices are provided that include two optical waveguides and at least one LED in an intermediate region between end faces of the optical waveguides so that radiation from the LED is coupled into the optical waveguides through the end faces. A de-coupler is on outer circumferential surface regions of each of the two separate optical waveguides. The de-coupler reflects the radiation guided in the optical waveguides so that the radiation passes through the optical waveguides and is coupled out of the optical waveguides laterally. The intermediate region has a length that is selected so that a brightness difference, measured perpendicular to an axis of the optical waveguides in the center of the intermediate region, at a distance of 10 mm perpendicular to the axis of the optical waveguides is at most 25% based on a maximum value of brightness along the axis of the optical waveguides.

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: 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.

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 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.
