LED38Sr (3.8 um IR LED)

Item Description

Final stock remaining.

Our spectrally specific IR LEDs are available with center wavelengths from 1.9 to 7 microns. Typical power levels are 10’s to 1000’s of microwatts depending on wavelength, duty cycle etc.

These devices are superior for the follow reasons:

  • Packaged to easily allow heat sinking and thus higher drive power and higher optical power output.
  • Ambient operation
  • Low power consumption (≤0.1 W)
  • Modulation from DC to VHF
  • High long-term stability

Also see the Universal Photon Source (UPS) Driver Board as an accessory to your emitter.
