Part of the Oslon Black family, there are 850nm versions intended for exterior applications such as night vision, pedestrian protection, pre-field recognition and lane detection, as well as 940nm versions for interior applications such as driver monitoring, seat occupancy detection and gesture recognition.
“Infrared light sources in a wavelength range <900nm are perceived by the human eye as a red glow. This red glow is largely suppressed at 940nm,” claimed the firm. “The leds are particularly bright, with an optical output of up to 2W in continuous operation. A high refractive index silicone is used for the lens, giving it a particularly low profile so that only very little light is lost from the sides.”
SFH 4715AS A01, SFH 4716AS A01 and SFH 4717AS A01 are 850nm and a beam angle of ±45°, ±75° and ±25° respectively.
SFH 4725AS A01, SFH 4726 A01 and SFH 4727AS A01 are 940nm and a beam angle of ±45°, ±75° and ±25° respectively.
Maximum operating temperature is 125°C.
