In many conveying applications, it’s critical to “see” or “read” products as they shoot through the process at high speed. To help with this function, Osram offers a small, versatile infrared LED for industrial and machine vision applications.

The Oslon Compact infrared light-emitting diode (IRED) closes the gap between high-power and low-power IREDs. The SFH 4710 is a mid-power LED with a typical output of 270 milliwatts (mW) from an operating current of 500 milliamps (mA).

It includes a small but powerful chip with an edge length of 750 micrometers (µm). With package dimensions of 1.6 mm x 1.2 mm x 0.8 mm, it is not much larger than the chip itself and is one of the smallest in its output class. It has excellent heat dissipation properties and can operate at high currents. The high output is made possible with state-of-the-art thin-film chip technology and, combined with the small package, opens up numerous applications, particularly where there is very little available space but performance demands are high. And, if required, components can be packed very close together to increase the optical output with a high degree of flexibility.”

This infrared light emitting diode has an emission angle of +/- 65° and does not need internal optics or reflectors. Without external optics, the IRED covers the near-field range of a few meters.

Its light can also be successfully injected into narrow-angle external optics. With external optics, it is suitable for machine vision tasks such as pattern recognition and 3D measurement because the wavelength of 850 nanometers (nm) is barely perceptible to the human eye but can be very easily detected by camera systems.
