Developer of thin film optical coatings, Deposition Sciences has introduced the new sophisticated Infrared Narrow Bandpass (IR NBP) Filters that are ideal for biological sciences, medical, and industrial instrumentation.
IR NBP Optical Filters
The enhanced bandpass optical filters provide better spectral performance with improved temperature stability and precise center wavelength placement that makes the infrared NBPs suitable for spectroscopic applications. NBP filters' IR spectral series allows the user to identify gases and to detect the concentration levels of HOx, CH4, and CO2 gases.
Optical coatings are utilized in non-diffractive infrared sensing solutions. The NBP filters of Deposition Sciences have repeatable and dependable transmittance aspects that are crucial for delivering high performance in gas sensing applications in the infrared region.
Lucas Alves, DSI's Thin Film Design Engineer stated that absorbing infrared radiations between wavelengths ranging from 2 to 20 microns offers a definitive signature for twisting, stretching, and/or bending of atomic bonds in a gas molecule. The IR bandpass filters enable spectra discretization through a gas sample at numerous identification wavelengths.
