Infrared LED empowers 2D facial recognition

To reduce the red glow that can occur with infrared light sources in the short-wave infrared range, Osram’s Synios P2720 emits light at a wavelength of 940 nm. Up to now, the sensitivity of IR cameras was only good if the light source had a wavelength of 850 nm, but the cameras have been further developed to give them greater sensitivity in longer wavelength ranges, which, in turn, improves the overall performance of the system.

The Synios P2720 delivers an output of 1,150 mW at 1 A and a radiant intensity of 360 mW/sr. Measuring 2.0 x 2.75 x 0.6 mm, the IRED is ideal for space-critical applications and has no optics, so you can install secondary optics in line with your requirements.
