Filters for gas analysis and gas detection corresponding to a central wavelength of 2.7 to 9.46 μm, with high blocking performance ranging from the visible to the far infrared region.
This is a bandpass filter designed to optimize the detection of bright lines in gas spectra, suitable for the mid-infrared region. We offer filters with a central wavelength range of 2.7 to 9.46 μm. A variety of filters are available for wavelengths commonly used in gas detection. They can be used for detecting gases such as H2O, CH4, CO2, CO, N2O, and O3.
