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.
Lms43LED-CG is an LED from a new line of high efficient light-emitting diodes with special glass covering. These LEDs reveal 3-5 times higher output optical power comparing to conventional LEDs and help to improve measurement accuracy. Lms43LED-CG model with a peak emission at ~4.1-4.3 µm is well appropriate for СО2 detection and for the analysis of other substances that have absorption bands in this range.
