ams OSRAM Synios SFH 4770S high power compact IR LED

Synios SFH4770S: high power compact IR LED for eye tracking and infrared illumination.

The new SFH 4770S is ams OSRAM's most compact infrared LED (IRED) in the high-power class. Its low height is of particular benefit in applications with space constraints. Compared to the OSLON family, the SFH 4770S takes it to the next level: the SYNIOS package reduces the footprint by almost one third and the height by around one quarter.

The high optical output of typically 1200 milliwatts (mW) and broad emission characteristics make this one-chip IRED ideal for facial recognition and eye-tracking systems which can activate applications in response to blinking instead of the usual double-click.

The basis for the new record emitter is the Synios package. It is extremely compact, measuring only 2.7 mm x 2.0 mm x 0.6 mm, and offers optimum light extraction. The SFH 4770S is the first component in which this package has been used for infrared emitters. Installed in the IRED is a 1 mm² emitter chip with a wavelength of 850 nanometers (nm) in which two emission centers are provided with the aid of nanostack technology.

SFH4770S is extremely attractive for designs that call for broad homogeneous illumination in a limited space (applications in mobile devices).

Emission angle of 120°:       even illumination
Typical radiant intensity:      375 milliwatts per steradiant (mW/sr) at 1 A

=>    Ideal for facial recognition and eye-tracking systems
