Osram IR LED will enable augmented and virtual reality headsets
Emitting in the infrared spectrum at 850 nm, the new Osram Opto Semiconductors SFH 4055 LED targets eye-tracking applications including headsets for augmented and virtual reality systems.
The IR LED has a tiny footprint that will allow integration into or around glasses in headsets worn by users, from gamers to scientists.
Osram based the new LED on the Firefly LED architecture that has been utilized as the basis for numerous LEDs that emit in the visible spectrum. The packaged LED emits light sideways. And the 1×0.325×0.55-mm footprint allows a number of the LEDs to be mounted in a typical headset. The LEDs direct IR light at the eye and the reflection is captured by camera-based sensors to track eye movement.
