UV-LED - innovative lightsource for industrial and medical purposes

The available sources of artificial ultra violet radiation (UV) nowadays can be used for medical and industrial applications depending on the energy density. UV-LED’s are currently replacing conventional mercury vapor lamps as well as gas discharge lamps. The increasing efficiency results in a new and broad field of applications. LED’s will also play a major role in the UVB and UVC field of application. mehr

Development of substrates for scanner mirrors and the potential for optimisation

High-performance laser beams for precision applications have to be deflected and steered; the laser source itself is moved only in exceptional cases. Instead, high-precision systems with fast-moving, steerable scanner mirrors are used for this purpose. The optical, mechanical and thermal requirements with regard to mirror surface and support require more and more frequently the use of specifically developed high-performance ceramics. mehr

Optical Grating Components - Manufacture and Application

Optical spectroscopy is a common analytical method, e.g. in colour measurement, chemical analysis and coating thickness measurement. Spectrometers, which use optical diffraction gratings as wavelength dispersive elements, are usually deployed for the UV to NIR wavelength range. Optical diffraction gratings are the heart of a spectrometer and thus... von Carl Zeiss Microscopy GmbH, Carl Zeiss Jena GmbH mehr
