A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

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 ...

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 ...

Current techniques for measuring nano/microplastic (N/MP) concentrations in soil require the soil organic matter content to be separated and have limited resolution for analyzing N/MPs sized <1 m.

A spectrometer is one of those tools that many of us would love to have, but just can’t justify the price of. Sure there are some DIY options out there, but few of them have the convenience or ...

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 ...

[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 ...

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 ...

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.

Researchers have devised a novel and simple method to measure nano/microplastic concentrations in soil using spectroscopy at two wavelengths A team of researchers has developed a novel and simple ...
