On the 6th March 2020, Astronomy Unit PhD student Clark Baker undertook the first on-sky testing of QMSPEC: a compact (size of a shoe-box), low-cost (~£10,000), high-resolution spectrometer. This ...

Researchers have demonstrated a spectrometer claimed to be orders of magnitude smaller than current technologies and capable of measuring wavelengths of light from ultraviolet to the near infrared.

How does a spectrometer work? In spectroscopy, photons encounter many components and undergo a variety of processes before registering as a spectrum. Let's see what happens to these photons once they ...

Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the details, though ...

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 ...

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 ...
