Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

Near-infrared spectroscopy (NIRS) is a noninvasive method used to monitor changes in hemoglobin concentration and oxygen levels in the body. This technique involves passing near-infrared light, ...

To investigate how melanin affects the accuracy of near-infrared spectroscopy (NIRS) measurements, researchers correlated the melanin levels of 35 adults with a diverse range of skin tones, measured ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...

Prepregs are reinforcement materials that have been pre-impregnated with either thermoplastic or thermoset resins. They are used in high-performance applications where mechanical properties and low ...

Coherent Corp. (NYSE: COHR), a global leader in photonics, today announced the launch of AxioView™ imaging fiber assemblies, designed for optical coherence tomography (OCT), near-infrared spectroscopy ...

CEA-Leti today presented new research at SPIE Photonics West highlighting major progress in the integration of quantum cascade lasers (QCLs) with silicon photonic platforms for mid-infrared (MIR) ...

Researchers in Brazil’s Amazonas state are testing easy-to-use scanners that can help them identify animal species they come across in the wild, Mongabay contributor Miguel Monteiro reported in June.
