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.


In 1600-5000 nm spectral range there are characteristic absorption bands of such important chemical agents as water H2O, methane CH4, carbon dioxide CO2, carbon monoxide CO, acetone CH3COCH3, ammonium NH3, C2H2, C2H4, C2H6, CH3Cl, OCS, C2HCl3, HCl, HOCl, HBr, H2S, HCN, CHBr3, H2CO, С2H4Cl2, HF, HNO3, NO2, SO2, glucose and many other organic and non-organic substances. Thus, there is a huge range of applications for optical analysis.

We propose our product as a new powerful base for optical absorption analysis. One of the greatest advantages of this method is that virtually any sample in virtually any state may be studied. Liquids, gases, films, powders, surfaces can all be examined with a proper choice of sampling technique. Using LED-PD optopairs for mid-infrared spectral range allows developing portable sensors with high reliability and adequate accuracy that can be successfully applied in different areas for matter analysis purposes.
