(Nanowerk News) Near-infrared (NIR) spectroscopy is a powerful technique for probing molecular compositions and structures non-invasively. However, traditional NIR spectrometers are often bulky and ...

Before a spectrometer can do any useful work, it needs to be calibrated to identify wavelengths correctly. This is usually done by detecting several characteristic peaks or dips in a well-known light ...

Researchers at CEA-Leti and CEA-IRIG-SyMMES have validated a chip-scale electron paramagnetic resonance (EPR) spectrometer that achieves unprecedented scan speed, spectral span, and sensitivity from a ...

A tiny polarization controlled metalens creates a flexible 3D sensor that shifts between precision and long-range modes, offering a new path toward adaptable optical measurement tools. (Nanowerk ...
