Applications of Infrared Bandpass Filters
Industrial Emissions Monitoring: Used to detect gases like CO₂, CH₄, and NOx in industrial exhausts and chimneys.
Environmental Monitoring: Employed to measure greenhouse gases such as CO₂ and methane in atmospheric studies.
Hazardous Gas Detection: Utilized in safety systems for detecting leaks of toxic or flammable gases like carbon monoxide or hydrocarbons.
Medical Applications: Applied in respiratory monitoring systems to measure CO₂ levels in exhaled air, especially in critical care settings.
Automotive Emissions Testing: Used to monitor exhaust gases for compliance with environmental regulations. -
Infrared Bandpass Filters in Gas Detection
Infrared (IR) bandpass filters are crucial components in gas detection systems, particularly those utilizing non-dispersive infrared (NDIR) technology. These filters are designed to transmit a specific range of infrared wavelengths that correspond to the absorption characteristics of target gases, allowing for precise identification and measurement.
NDIR Technology: NDIR gas analyzers use IR bandpass filters to isolate the wavelengths absorbed by specific gases. This method involves passing infrared light through a gas sample and measuring the absorbed wavelengths to determine gas concentration. The filters ensure that only the relevant wavelengths reach the detector, improving specificity and sensitivity
