Collection: Infrared (IR) Bandpass Filter

Infrared (IR) bandpass filters are used to transmit light within a specific wavelength range in the infrared spectrum, while blocking all other wavelengths. Here are some of their applications:

• Gas analysis: IR bandpass filters are frequently used to detect and measure the concentration of specific gases.Different gases have unique absorption lines in the infrared spectrum. By using a filter that transmits only the wavelength corresponding to a particular gas, scientists can measure the amount of that gas present with minimal interference from other gases. This technique is known as Non-Dispersive Infrared (NDIR).

• Environmental monitoring: IR bandpass filters can be used to monitor pollutants or other substances in the environment by selectively transmitting the wavelengths they emit or absorb.

• Security and FLIR (Forward Looking Infrared) applications: IR bandpass filters can be used to enhance the image quality of night vision devices by filtering out unwanted light, such as visible light or thermal radiation from background sources. This allows for better detection of objects of interest.

• Biotech, biomedical, and quantitative chemical applications: IR bandpass filters are used in various instruments to isolate specific molecular vibrations for analysis. This allows scientists to study the properties of various materials and biological samples.
