Osram Opto Semiconductors’ new SFH 4787S infrared LED (IRED) for iris scanners illuminates the eyes so evenly that the software identifying the iris pattern now hardly needs to correct artefacts.
New Oslux IRED ensures even illumination, simplifying identification of unique iris patterns.

Like its predecessor (SFH 4786S), its direction of emission is slightly angled rather than vertical, thus simplifying the design process by eliminating the usual mechanical aids. Osram Opto Semiconductors will be presenting the new SFH 4787S IRED at the upcoming Mobile World Congress.
Iris recognition is among the most reliable biometric identification methods available today. With this safeguard, iris scanners illuminate the user’s eyes with infrared light and a camera takes a photograph. Special software then analyzes this photo to detect the iris pattern, which is unique to each individual. Once confirmed, the device is unlocked for the user.
Two years ago, Osram Opto Semiconductors was first to market an infrared LED (the SFH 4780S) that brought this technology to smartphones and other mobile devices. This was followed by a version with a slightly angled direction of emission (SFH 4786S), which meant that designers no longer needed mechanical aids to tilt the entire LED to align the angle of emission with the camera’s field of view.
