Optical filter materials
WebOptical filters with a band-pass region corresponding to the peak absorption band of a selected gas (or gases) result in the intensity of filtered IR light reaching the detector depending only on the concentration of the chosen gas. Table 1: Mid and long wave infrared gas absorption peak wavelengths Search: Showing 1 to 7 of 7 entries In general, a given optical filter transmits a certain percentage of the incoming light as the wavelength changes. This is measured by a spectrophotometer. As a linear material, the absorption for each wavelength is independent of the presence of other wavelengths. A very few materials are non-linear, and the transmittance depends on the intensity and the combination of wavelengths of the incident light. Transparent fluorescent materials can work as an optical filter, …
