Thorlabs' long-optical-path absorption cells are used primarily for weak-trace-gas absorption spectroscopy applications such as environmental monitoring, combustion processes, medical diagnostics, and fundamental atomic and molecular physics. This gas cell provides a relatively long absorption path for the sample volume of only mL. Gas sample cell Generating a spectrum on an FTIR spectrometer follows this process: 1. The Source: Infrared energy is emitted from a glowing black-body source. This beam passes through an aperture, which controls the amount of energy presented to the gas sample (and, ultimately, to the detector). 2. Multiple-pass or long path absorption cells are commonly used in spectroscopy to measure low-concentration components or to observe weak spectra in gases or liquids. Several important advances were made in this area beginning in the s, and research into a wide range of applications continues to the present day.
