Osram Opto Semiconductors Oslon Compact SFH 4710 IRED

The Oslon Compact infrared light-emitting diode (IRED) has been added to the Osram Opto Semiconductors range. Despite its small package it offers good output and can therefore be used for such tasks as surveillance, digital image processing, 3D measurement, pattern recognition and gesture detection.

The infrared Oslon Compact SFH 4710 has been designed for industrial applications. As a mid-power LED with a typical output of 270 mW from an operating current of 500 mA, it occupies the output range between the company’s Power TopLED and Oslon Black.

The IRED accommodates a small powerful chip with an edge length of 750 μm and half the footprint of standard chips in the Oslon Black. With package dimensions of 1.6 x 1.2 x 0.8 mm, the IRED is not much larger than the chip itself and is therefore one of the smallest in its output class.

The infrared light emitting diode has an emission angle of ±65° and does not need internal optics or reflectors. Its light can, however, be successfully injected into narrow-angle external optics.

With external optics, it is suitable for illumination in surveillance applications and for machine vision tasks such as pattern recognition and 3D measurement because the wavelength of 850 nm is barely perceptible to the human eye but can be very easily detected by camera systems.
Without external optics, the IRED covers the near-field range of a few metres and is therefore suitable, for example, for eye tracking and gesture detection.
