Premstaetten, Austria and Munich, Germany– ams OSRAM, a global leader in optical solutions, extended its OSLON P1616 family of small, high-power infrared LEDs, launching emitters which produce a field of illumination optimized for the square or rectangular field of view (FoV) of IR cameras. The OSLON P1616 products, which have a footprint of 1.6mm x 1.6mm, are among the industry’s smallest high- power IR LEDs. The new products have a low profile which makes them ideal for use in the face recognition camera system mounted in the thin bezel of a laptop computer, or in smart doorbells.
Benefiting from advanced optical technology, the new OSLON P1616 LEDs produce a precisely shaped beam which matches the square or rectangular FoV of IR cameras. The new LEDs provide as much as 25% more light in the FoV1 and more homogeneous illumination than LED without dedicated optics and pure Lambertian light distribution.
‘These latest members of the P1616 family produce remarkably high optical output power from such a small package. The excellent performance-to-size ratio of these LEDs makes them the ideal solution for applications in which board space or height – or both – are limited,’ said Dominic Bergmann, Product Marketing Manager Business Line Visualization and Sensing at ams OSRAM.
The new LEDs’ optimized beam shape reduces the development effort for manufacturers of IR camera modules and systems, providing more uniform illumination of the FoV and easing system calibration.
The new OSLON P1616 LEDs are:
- The 850nm SFH4172 and 940nm SFH4182S, in a lensed package which is just 1.31mm high. They produce a homogeneous illumination which has a half-angle of ±65° to fit the square field of view of IR cameras.
- The 850nm SFH 41747 and 940nm SFH 41847S, in a lensed package which is 1.36mm high. They produce a homogeneous illumination which has a 100° x 140° radiation pattern to fit the rectangular field of view of IR cameras.
The optical output (total radiant flux) from the new OSLON P1616 LEDs is 800 mW for the SFH4172, 1,320 mW for the SFH4182S, 700 mW for the SFH 41747, and 1,150 mW for the SFH 41847S. In addition to laptop computers and smart doorbells, applications include CCTV cameras, access control, eye tracking, and gesture recognition as well as emerging applications such as machine vision and medical treatment.
