IR Light Emitting Diodes

Infrared Emitting Diodes (IREDs) are solid state light sources emitting in the near infrared part of the spectrum. The emission wavelength is closely matched to the response peak of silicon photodiodes and phototransistors. This product line provides a broad range of lens and power output options. Both top and side radiating cases are available as well as a wide range of emission beam profiles. These IREDs may be operated in either CW or pulsed operating modes.

IREDs with wavelengths 770 nm, 870 nm 880 nm, 940 nm, and 950 nm are offered for applications like smoke detection, encoders, transmissive and reflective optoswitches.

What are IR Diode Solutions used for?
An infrared diode is a light source that emits light in the near-infrared (NIR) spectrum. Thanks to its ability to emit light over a narrow bandwidth, it can be used as a reliable, ideal light source in many applications. For instance, it can be combined with phototransistors and detectors within integrated assemblies to produce optical switches, retro sensors, optoisolators, and other sensing systems.
What types of Infrared LEDs do you offer?
The IR diode solutions offered by Excelitas come with varying peak wavelengths, beam angle width, packaging, reverse voltage and current, response time, junction capacitance, and peak forward current, among others. Our product line of infrared light emitter products consists of diodes at the following wavelengths:  
  • 880 nm IR Light Emitter Diodes our 880 nm infrared diode series consists of three standard chips packaged in nine different products, offering a wide range of options in terms of lens, mounting, and power output equipment. These packages include narrow and wide-angle emitters as well as side and end-radiating cases. To deliver the highest output at 880 nm, our infrared products are equipped with high-efficiency GaAIAs liquid phase epitaxial chips and are mounted P-side down to facilitate energy delivery.
  • 940 nm IR Light Emitter Diodes our 940 nm series comprises two standard chips manufactured in three different packages. As with our 880 nm series, these IR diode devices also use high-efficiency GaAs liquid-phase epitaxial chips. These chips are mounted P-side down to produce the highest output at this wavelength. Meanwhile, the metal header TO-46 is double-bonded to make the device more reliable, especially when it comes to pulse applications.
What are the applications of Infrared Light Emitting Diode Solutions?
