Advanced UV for Life exhibits custom-tailored UV LED developments at micro photonics fair

In hall 7.2 c, booth 207, at the micro photonics 2016 International Congress & Expo in Berlin, Germany (11–13 October), the consortium Advanced UV for Life is presenting a selection of current developments.

In the interdisciplinary consortium, 37 scientific institutions and industrial companies with expertise along the entire value chain of ultraviolet light-emitting diode (UV LED) technology - from development to applications - have partnered to promote the technological development, availability and use of UV LEDs. Funded by Germany's Federal Ministry of Education and Science (BMBF) the program 'Twenty20 - Partnership for Innovation', Advanced UV for Life is managed by the Ferdinand-Braun-Institut (FBH) and addresses customized solutions in application fields including medicine, environment & life sciences, water treatment, and production.

At the micro photonics fair, Advanced UV for Life is represented by the following partners:

Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) develops UV LEDs for Advanced UV for Life consortium partners, focusing on the UVB and UVC wavelength ranges. The light sources offer tailored properties for various applications, from medical diagnostics and fluorescence spectroscopy to surface treatment and disinfection. At the micro photonics fair, FBH is presenting its competencies in UV LED development from the chip to the final radiation module. Exhibits include a UV LED-based demonstrator for water disinfection purposes.

FBH spin-off UVphotonics NT GmbH develops highly efficient, reliable and customizable UV LEDs in the UVB (280-320nm) and UVC (< 280nm) wavelength ranges. The devices can be used for water purification and disinfection, phototherapy, sensing, and UV curing applications, among others. The LEDs are tailored to meet the customer-specific needs in terms of emission wavelengths, emission characteristics, power ranges, and chip layouts. UVphotonics also offers consultation on the integration of UV LEDs in application systems of industrial partners.

sglux SolGel technologies GmbH targets the development of UV sensing technologies. The firm's portfolio includes a PTB (Physikalisch-Technische Bundesanstalt)-traceable calibration chain for the determination of optical power, irradiance, radiation characteristics and spectral distribution of UV LEDs developed by the consortium. Due to systematic monitoring of the degradation behavior under defined conditions, optical system components can be adapted to the requirements of different applications.

OSA Opto Light GmbH develops UVB and UVC LED-based assemblies and modules for applications addressed by Advanced UV for Life, targeting the interface between device developers and end-users of UV LED-based technologies. At the fair, the firm is exhibiting its highly efficient LED radiation source OLM-021A-b, which is designed for photochemical processes in the 365–440nm wavelength range. The system has been tested successfully for the exposure of different materials, e.g. polystyrenes and polyacrylates up to 10mm thickness, printing inks and photoresists based on novolak, epoxy resin and acrylate.

micro resist technology GmbH is applying and demonstrating the concept of UV LED-based micro-lithography by displaying patterned resist demonstrators. The ability to micro-pattern negative- and positive-tone photoresists with single-wavelength UV LED exposure at UV-vis, UVA and UVB aims to reduce equipment complexity and thus manufacturing costs. Photoresists with film thicknesses from 500nm to 50µm and the high-intensity UV LED modules need to be adapted to each other in order to achieve good pattern resolution featuring illumination homogeneity over the substrate and reduced exposure time.
