In recent years, interest in gas analysis has risen due to its potential for application to the greenhouse gas problem and measures against infectious diseases. Hamamatsu Photonics handles photosensors and light sources suitable for gas analysis. Here, we introduce an example of CO2 measurement using an InAsSb photovoltaic detector and a mid infrared LED. NDIR (Non-Dispersive Infrared) detection method uses an optical filter to extract and detect only the wavelengths required for gas measurement. This method offers superior reliability and maintainability due to a simple detection principle, which uses no moving parts. Mostly containing cost-effective optical parts, it is non-dispersive and does not use image sensors. High cost performance optical parts are used in many measuring devices, including but not limited to portable measurement safety (explosive gas detection) devices and fixed environmental measurement devices.
