Osram Opto Semiconductors is launching its smallest sidelooking infrared LED to date. The new SFH 4055 is based on the proven Firefly platform, used widely for LEDs in the visible spectrum. The new transmitter, which has a wavelength of 850 nm, is primarily targeted at eye-tracking systems in augmented and virtual reality headsets.
Eye-tracking systems use multiple infrared LEDs to illuminate users’ eyes and capture the light reflected back with camera sensors. This allows these systems to compute the position of the user’s pupil and work out what direction the user is looking in. Incorporating this technology into virtual
