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: 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: A lighting device is provided that has a light source arrangement with a plurality of semiconductor-based light sources in the form of light-emitting diodes. The light sources are bundled or collimated such that they each emit light in differently directed light cones with adjacent light cones overlapping. The lighting device has an adjusting device for adjustment of the direction of illumination and an actuating circuit connected to the adjusting device. The adjusting device adjusts intermediate stages for which the light-emitting diodes of adjacent and overlapping light cones operate and with varying light intensity in such a way the focal point of the light field produced by the light-emitting diodes lies between the focal points of adjacent light cones.

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.
