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.

Pulse mode

LEDs offer numerous benefits due to possibility for different operation modes. Optical parameters of light emitting diodes strongly depend on the regime of operation that you choose. To obtain maximum peak power we recommend using short pulse modes (less than 50 ms).
