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: A fiber-optic conversion module is provided as part of a lighting device on a vehicle. The module includes optical fibers with connectors, a light exit head, and a converter mounted on a cooling element. Shorter wavelength excitation light is fed to the optical fibers that emit the excitation light towards the converter arranged at an angle relative to the beam direction, at a light spot that remits useful light in a radiation angle in form of a cone of useful light and reflects excitation light as a Fresnel reflection substantially outside the cone of useful light, where Fresnel reflection is made harmless by a light stop.

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.

Abstract: An illumination system is provided that includes a laser light source, a light guide, a connector, and an emission element. The laser light source has a numerical aperture. The light guide has a proximal end and a distal end. The connector has a connector housing and connects and/or assigns the laser light source at the proximal end. The emission element is at the distal end. The connector housing has a device that reduce an influence of a range of variation of the numerical aperture so that an emission behaviour of the emission element is independent of a range of variation of the numerical aperture.

Abstract: A flexible light guide that has a homogeneous light emission with high luminance is provided. The flexible light guide is provided by a side-emitting light guide. The side-emitting light guide includes a light-guiding fiber designed as a side-emitting fiber so that light guided in the fiber is scattered out along a longitudinal direction in a distributed manner. The guide also includes a tube that surrounds the fiber. The tube is designed to be light-scattering and translucent so that light emitted from the fiber can traverse the tube with scattering. The tube is surrounded by a cladding. The tube and cladding are made of plastic.

Abstract: A receptacle for a plurality of light-guiding fibres is provided. The receptacle has a glass part with a first end face, a second end face, a plurality of rectilinear channels extending between the first and second end faces, and a lateral surface between the first and second end faces along a longitudinal direction. The glass part has a length defined between the first and second end faces where the length is greater than a largest transverse dimension of the glass part. The rectilinear channels are open at the first end face and/or the second end face so that the light-guiding fibres are receivable therein, respectively. The rectilinear channels have a channel length that is greater than a channel transverse dimension. The lateral surface has a parting surface thereon.
