New optoelectronic devices for the Mid-Infrared spectral range open completely new possibilities for portable sensors creation. Using Mid-infrared LED-PD optopairs allows developing an instrument that is smaller, less expensive and versatile.

LED Models

We offer a line of standard one-element LEDs for the near- and middle-infrared spectral range from 1.0 up to 4.6 µm.
