Infrared LEDs

Infrared LEDs

Infrared LEDs (IR LEDs) emit light in the near infrared range with a wavelength of 700 to 1000 nanometers that is not visible to the human eye. Even before the first visible LEDs were manufactured in red, infrared LEDs were developed. At the beginning, however, both had little practical relevance, as light-emitting diodes were expensive to produce and cost up to 200 US dollars per unit until the 1970s. Today, an IR diode is usually used in combination with an IR receiver for wireless communication and is mainly used in the electronics industry between different machines.

Infrared LEDs can be categorized according to their wavelength and the associated application. The most common are:

  • 830 nm - used with automatic card reading systems
  • 850nm – used for night vision cameras, CCTV surveillance systems and digital photography
  • 880 nm – used in medical applications, infrared illumination and optical communications
  • 940 nm – used in with remote controls, is based on aluminium gallium arsenide and is the most widely used due to its low production costs.

Certain radiation detectors can measure the light from infrared LEDs and thus check their functionality. But even digital cameras without appropriate filters are sensitive to infrared light and can therefore perform this task.
