A suspended chalcogenide waveguide achieves record ppb-level gas detection in the near-infrared, enhancing sensitivity for ...

Infrared spectroscopy is increasingly established as a way to carry out in vitro diagnostic testing, thanks to its ability to detect the molecular profiles of many biomarkers. What has been missing, ...

Each molecule has its own unmistakable tone – a vibrational “fingerprint” that reflects not only its chemical structure but also the nanoscale environment around it. But the voices of individual ...

NIR spectroscopy concerns the analysis of how NIR light and matter interact. In spectroscopic analysis, light is determined by the wavelength, not by the applied energy. The wavelength of light is ...

Fourier transform infrared (FTIR) spectroscopy is the preferred method of infrared spectroscopy. In this approach, IR radiation passes through a sample, where some of it is absorbed by the sample ...

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 ...

Physicists have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices ...

This paper explores the differences and similarities between Raman and infrared spectroscopy in regard to unknown material identification and reaction monitoring. While these techniques share ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...
