Abstract: A method and device for aligning a light spot of light exiting from at least one light guide on an optical converter are provided. The device includes a light guide from which light exits and is incident on an optical converter to at least a substantial fraction, thereby forming a light spot thereon, wherein the exit surface of the fiber has an angle relative to the longitudinal axis of the fiber which is different from 0°, and the position of the light spot on the converter is aligned by adjusting the angle. A conversion module as a part of a lighting device is also provided that is operated with excitation light of a light source using a fiber-optical light guide.

Abstract: An optical layered composite includes: a substrate having a front face, a back face, a thickness ds between the front face and the back face and a refractive index ns; and a coating applied to the front face. The coating comprises a group A of coating layers having a refractive index of 1.7 or more and a group B of coating layers having a refractive index of less than 1.7. The sum of the thicknesses of the layers of the group A is at most 55% of the total thickness dc of the coating.

Abstract: An illumination system is provided that includes a spatial fiber arrangement with an optical element at the distal end of the fiber arrangement. The fiber arrangement has a first region including individual fibers with a significantly smaller active diameter in comparison with the individual fibers of a remaining region. The optical element at the distal end is assigned the remaining region. The fiber arrangement can be a rigid fiber rod that includes an intermediate region provided between the first region and the remaining region. The intermediate region suppresses stray light transfers between the first and remaining regions. The fiber arrangement can include an optical coupling element at a proximal end of the fiber rod.

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 a medical technology therapy and/or diagnosis system is provided. The system includes a light source, an optical waveguide, and an optical element in the form of a diffuser element. The optical waveguide has a first end that is connectable or assignable to the light source and the diffuser element is arranged at a second end of the optical waveguide so that light from the optical waveguide is injected into the optical element. The optical element has a lateral surface covered by a reflector layer at least in a section thereof. The reflector layer includes a mirror layer. The optical element has a light-reflecting area covered by the reflector layer and a light-transmissive area that is free of the reflector layer. Thus, light injected into the optical element is reflected on the light-reflecting area and emitted from the light-transmissive area.

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: 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.
