Infrared Band pass Filter
Infrared Narrow Band Filters are designed for the detection and measurement of atmospheric gases. Many gases show a specific absorption line in the mid to far infrared range. With a filter which allows the monitoring of this specific gas absorption, the measurement of gas concentration is possible.

Application

Infrared absorption (NDIR) gas sensing, Environment management system

Property

Technology is based on infrared (IR) absorption of radiation called the NDIR(Non – Dispersive Infrared) technique. By detecting the amount of light absorbed, within just a narrow band width that coincides with the resonance wavelength of the specie selected, one gets a measure of the number of molecules, free from interference of other species.
