UVphotonics showcasing custom UV LEDs and modules at Photonics West
Together with Berlin-based Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) in the German Pavilion (booth 4545) at Photonics West 2020 in San Francisco, CA, USA (4-6 February), UVphotonics NT GmbH – a spin-off from FBH and Technische Universität Berlin (TU Berlin) – is presenting novel UV LED developments with emission wavelengths ranging from 330nm down to as low as 230nm.
UVphotonics notes that UV LEDs have opened up new prospects due to benefits such as increased design flexibility, energy savings and reduced overall cost. Their customizable wavelengths, low operation voltages, ability to be rapidly switched and dimmed along with their compact size make them versatile light sources configurable to a multitude of applications, including water purification, disinfection, medical diagnostics, phototherapy, plant growth, UV curing and sensing.
Specifically, UVphotonics is presenting UVB and UVC LEDs with 10,000hr lifetime and output powers of up to 45mW at 310nm and 30mW at 265nm. Also showcased are fully packaged UVC LEDs with single emission peak at 230nm and an output power of 1.6mW at 100mA. Moreover, the firm’s product portfolio has been expanded to UV LED modules with integrated driver circuits.
UVphotonics spin-off tailors its products to customer-specific needs in terms of emission wavelength, emission area and spatial emission characteristics. Together with the FBH, the firm covers the full UV LED technology chain: R&D on (Ga,Al,In)N UV LEDs with all stages of device fabrication in-house. The portfolio ranges from design to epitaxial growth to chip processing, packaging and up to complete turn-key modules, which are ready to use in applications. Also, in the neighboring booth, FBH is presenting its diode laser developments.
