OSLUX® SFH4786S Designing iris scanners just got easier
The infrared SFH 4786S LED from Osram Opto Semiconductors provides the basis for extremely low-profile systems for iris scanners. A new feature is the slight sideways tilt of its direction of emission. The emitter no longer has to be mechanically aligned with the field of view of the camera, which makes the design much simpler. the SFH 4786S emits light with a wavelength of 810 nanometers (nm). In this spectral range it is possible to achieve high-contrast images for all iris colors.
