Microhybrid
Microhybrid have been developing and producing innovative microelectronics and infrared sensors for over 25 years. Online shop in english.
Microhybrid.com offers 1-4 band thermal (thermopile or IR) sensors, IR emitters and ready made dual-band IR spectrometers for gas sensing. they also offer a range of bundled development products. For instance a bundle for alcohol detection applicable for use in wineries and small breweries.
Boston electronics
Boston electronics offers (UV, Visible, to IR and THz photodetectors](https://www.boselec.com/product-category/ir-uv-thz-photodetectors/), steady state IR emitters and ?. they also offer a range of ?bundled development products.
The thermopile (IR) sensors are available as 1-4 band sensors housed as TO-8, TO-39, TO-46 packages.
Boston electronics offers both broad band IR emitter and IR LEDs with center wavelengths from 1.9 to 7 microns.
The Application Note NDIR-Measurement gives a clear overview of using thermopile (IR) sensors for detecting organic gas molecules.
