Compact versatile infrared LED opens up numerous industrial applications
Despite the device’s small package it claims to offer impressive output. The IRED can be used, for example, for such tasks as surveillance, digital image processing, 3D measurement, pattern recognition and gesture detection.
The new infrared Oslon Compact SFH 4710 has been designed especially for industrial applications. As a mid-power LED with a typical output of 270 mW from an operating current of 500 mA, it is a welcome addition to the product portfolio of Osram Opto Semiconductors, occupying the output range between Power TopLED and Oslon Black.
The IRED accommodates a small 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 mm x 1.2 mm x 0.8 mm the Oslon Compact 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. The IRED’s light can be injected into narrow-angle external optics.
With external optics the device is ideal 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 easily detected by camera systems.
Without external optics the IRED perfectly covers the near-field range of a few meters and is suitable for example for eye tracking and gesture detection.
