A spectrometer is an instrument that is often employed to examine, identify, and precisely gauge electromagnetic radiation emanating from a substance. This aids in identifying the elemental ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

In this article, we discuss the principle behind the functioning of glow discharge optical emission spectrometry, some of its practical applications as well as studies that have used the technology in ...

Here at Hackaday, we love to see projects re-visited and updated after we’ve covered them on the site. It’s always exciting to see what the creators come up with next, and this Pi-Based Spectrometer ...

As much as we know today about the planets of the solar system, it’s almost incomprehensible that a mere 50 years ago we knew almost nothing about them. Observations of even Mars and Venus, Earth’s ...

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

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...
