Gas detection demonstration
Gary Spingarn, our product manager for infrared devices, introduces a gas detection demo for carbon dioxide. The demo showcases a gas detection module that will be featured at Photonics West 2024. The module consists of a 4.3 micron LED and two InAsSb photodiodes with bandpass filters. One diode is used for measuring carbon dioxide concentration at 4.3 microns, while the other serves as a reference channel at 3.9 microns.
