Ams and OSram have introduced two new facial recognition infrared leds for narrow-bezel display designs

     Ams has announced the introduction of two infrared leds (IRED) specifically developed for 2D facial recognition systems: SFH4171S and SFH4181S. Both IRED, when used, emit infrared light at the user's face, which is photographed by an infrared camera, and if the image taken matches the image stored in the system, the device is unlocked. The two products have the obvious advantage of ultra-small size, which can achieve the ultra-narrow bezel design of laptops, which is also the current popular trend of laptops.

     "With the help of these two infrared leds, we continue to simplify the integration of security applications in laptops, providing manufacturers with new design options for future models," said Bianka Schnabel, product manager for ams and OSram Optical Semiconductors. Unlocking a laptop with biometrics eliminates the hassle of entering a password, ensuring that users can access their laptop quickly and easily after a break.

     Ams and OSram offer IRED at two wavelengths: SFH4171S at 850 nm and SFH4181S at 940 nm. In the SFH4171S wavelength range, customers can clearly feel the high sensitivity of the infrared camera. The SFH4181S avoids the "red exposure" effect visible to the human eye, which is generally required to avoid the "red exposure" effect in consumer electronics applications. Both products come in an extremely compact Oslon P1616 package. Even including optical lenses, the installation space required for this product is only 1.6mm×1.6mm×1.71mm. Despite their small size, both IRED deliver excellent optical power of 1150mW and beam intensity of 680mW/sr at 1A. Special primary optics condense the beams together at a 35° beam Angle to improve performance and make it easier for infrared cameras to take high-quality images.
