[Project 326] wanted to know exactly what gas was in some glass tubes. The answer, of course, is to use a spectrometer, but that’s an expensive piece of gear, right? Not really. Sure, these cheap ...

When light reflects off a surface, not all of it reflects off at the same wavelength; some photons impart a portion of their ...

A new high-tech spectrometer is helping Ohio University researchers see the unseen. By revealing molecular structures with ...

Color, as the way light's wavelength is perceived by the human eye, goes beyond a simple aesthetic element, containing important scientific information like a substance's composition or state.

For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory ...

New research published the journal Biomedical Optics Express describes a smartphone-compatible spectrometer held and directed like a pencil. According to the article's authors, this novel device could ...

Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system ...

The composition of complex mixtures of molecules can be determined using NMR spectroscopy. Each of the thin glass tubes is filled with an extract of sea water that contains a few milligrams of ...

Spectral images, which contain more color information than is obtainable with a typical camera, reveal characteristics of tissue and other biological samples that can't be seen by the naked eye. A new ...
