Bandwidth Control of Mid-IR bandpass Filters to Optimise Sensitivity of NDIR Methane Sensors
Here, we discuss the application of a very-narrow bandpass mid-IR optical filter designed to capture the Q-branch of the methane ν 3 absorption band, providing high-sensitivity requirements for NDIR sensing in Digital Dairy Farming applications.
