Description
UVTOP335 is a series of AlGaN based deep UV-LEDs with a typical peak wavelength of 340nm and optical
output power of 240-400 µW. It comes in hermetically sealed TO39 or TO18 metal can package with ball lens,
hemispherical lens, or flat glass window configuration. UVTOP335 is widely used for blood gas
measurements, nitrogen urea measurements, and UV-curing applications
