Overview

We manufacture LEDs tuned to the absorptions of the major gases of interest

They are ideal for use in portable pollution monitoring instruments based on optical absorption

Advantages of the LEDs include;

  • Intrinsically safe room temperature operation
  • Low power consumption
  • High emittance for smaller optics
  • High modulation bandwidth, high speed operation - faster instrument  response time
  • Robust, high stability & reliability
  • Long operating lifetime
