v 1.0 11.07.2013
Description
UVTOP270-SMD is a series of AlGaN based surface mount deep UV-LEDs with a typical peak wavelength of
275nm and optical output power of 400-800 µW. It comes in ceramic SMD package with different lens
configurations available. UVTOP270-SMD is widely used for forensic analysis, disinfection, water
sterilization, protein analysis, DNA sequencing and drug discovery.
