The
SFH 4787S infrared LED provides even illumination for iris scanners to detect and
identify unique patterns in the eye. Its flat intensity distribution optimizes
the reflector and lens to create a constant intensity across the emitted beam,
simplifying identification of distinctive iris patterns with little need to
correct for artifacts, thus increasing accuracy in analysis and detection.

It features a slightly angled direction of
emission, tilted by 8° and ±18° emission angles. It offers an optical output of
720 mW at a current of 1 A and a radiant intensity of 1,000 milliwatts per
steradian (mW/sr). Its compact 3.5 x 3.5 x 1.6-mm Oslux package targets safeguarding
mobile and other small devices.
