Debuting as the first member of a family of infrared (IR) emitters, the OD-850W gallium aluminum arsenide (GaAlAs) LED features a wide-emission angle and an optical output of 40 mW at 100 mA with a peak emission wavelength at 850 nm. Notably, the 850-nm wavelength is more closely matched to the peak response of photo transistors and opto integrated circuits. Pricing for OD-850W IR LEDs is $2.80 each/100.
