UV Aluminium Coating for Spectrometers

Basic information

Gas Detection Systems utilize Interference Bandpass Filters to accurately detect and identify specific gases. Each gas emits a unique wavelength, making it identifiable when using the appropriate Interference Bandpass Filter. For instance, Carbon Monoxide (CO) emits at 4.73μm, Nitric Oxide (NO) emits at 5.24μm, Nitrogen Dioxide (NO₂) emits at 6.17μm, Sulphur Dioxide (SO₂) emits at 7.42μm, Hydrogen Chloride (HCl) emits at 3.55μm, and Carbon Dioxide (CO₂) emits at 10.7μm. Knight Optical offers a comprehensive selection of Interference Bandpass Filters that are specifically designed for gas detection applications. These filters are customized to transmit in the infrared spectrum, ensuring optimal performance. With our extensive experience, we can provide a range of narrow, standard, broadband, and extra broadband filters that have a high optical density of 4 as a standard feature. However, we can customize these filters according to your specific requirements. For more details, please refer to the provided PDF or contact us for further information.
