Spectroscopy is the absorption, emission, and scattering of electromagnetic radiation by atoms and molecules, which may be in the gas, liquid, or solid phase.
Chromacity is leading the way in spectroscopy applications across the near and mid-IR. Discover how the Chromacity OPO is used in stand-off detection and FTIR techniques to distinguish between multiple gases, including hydrocarbon emissions, in a recent study with The Institute of Photonics and Quantum Sciences (IPAQS) at Heriot Watt University.
The Chromacity OPO can be integrated into an FTIR spectrometer, providing the ability to interrogate multiple chemical signatures in real time (at a high resolution). Our near-IR OPO has a broad bandwidth across the 3µm-3.5µm to quantify gases such as of methane, ethane and benzene in a single measurement with resolutions of 0.05cm-1.
The high powers of the near-IR OPO have demonstrated open-path stand-off detection measurements beyond 100m.
Spectroscopy across the fingerprint regime provides that ability to characterise volatile organic compounds with complex chemical signatures and the high brightness of our mid-IR OPO spans the 5-12µm and can be used in a number of these set-ups.
It can also been used to characterise and differentiate between compounds, such as VX and Sarin, as well as pharmaceutical powders such as aspirin and ibuprofen
