Understanding the properties of different materials is an important step in material design. X-ray absorption spectroscopy ...

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 ...

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 ...

A good portable Raman spectrometer bridges the gap in capability, performance, and size between benchtop and handheld Raman spectroscopy. It allows new point-of-use applications in industry and ...

[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 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 ...

The instrument uses randomly textured lithium niobate and its developers have used it for astronomical imaging and materials ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Researchers 3D printed a mini quadrupole mass filter, a key component of a mass spectrometer, that performs as well as some commercial-grade devices. It can be fabricated in hours for a few dollars ...

We describe a new technique for determining the instrumental profile (IP) of an astronomical spectrometer. A known intrinsic spectrum of a reference source is convolved with a parameterized IP and ...
