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 ...

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 ...

[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 ...

The PbS QD filter array coupled with an InGaAs image sensor forms a high-performance NIR computational spectrometer capable of distinguishing materials and measuring alcohol content with high accuracy ...

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 ...
