UV crystal LEDs for spectroscopy by Crystal IS
Optan ultraviolet crystal (UVC) light-emitting diodes (LEDs) from Crystal IS (Green Island, NY) are based on native aluminum nitride (AIN) substrates for increased detection sensitivity in analytical and life sciences instrumentation such as spectrometers. They overcome limitations associated with traditional UV lamps, including deuterium and xenon flash lamps. Available peak wavelengths and power bins range from 250 to 280 nm and from 0.5 to 2 mW, respectively, for utility in spectroscopy applications because of their high spectral quality. Full availability for all bins under 3 mW is anticipated for next quarter, with higher power bins (3–4 mW) available in fall 2014.
