In this paper we present an electro-optical sensor system suitable for the detection of CO2. The system comprises a microheater (used as an infrared source), a copper chamber (required to direct the radiation toward the detector), two sapphire windows (which close the chamber without absorption of infrared radiation), an optical filter and a thermopile (infrared detector)

Abstract
In this paper we present an electro-optical sensor system suitable for the detection of CO2. The system comprises a microheater (used as an infrared source), a copper chamber (required to direct the radiation toward the detector), two sapphire windows (which close the chamber without absorption of infrared radiation), an optical filter and a thermopile (infrared detector)File in questo prodotto:
