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 ...

Spectroscopy, in its broadest sense, is the term given to the investigation and measurement of spectra produced when a substance interacts with or emits electromagnetic radiation. All known matter ...

In the last few weeks I've been working on a slightly more formal version of this post on black-body radiation for use in something else. One of the tricky things in writing about the development of ...

Over the years, dispersive Raman spectroscopy has been increasingly employed for sample analysis in the areas of biomedical research, material identification, archeology and art, and forensics thanks ...

value output is carried out via a USB connection, which also serves as a power supply. In addition, the wavelength information is available as voltages of up to 4.096V at the analogue output. The ...

NASA's SPHEREx has mapped the entire sky in 102 infrared colors, revealing hidden details about galaxies and the early universe.

As data rates in optical networks increase, designers need to pay increasing attention to peculiarities in the fiber-optic medium.One of the most important of these peculiarities is dispersion, ...

Multi-wavelength analysis of hydrodynamic data collected on the latest analytical ultracentrifugation instruments provides additional resolution and insights into hetero-interacting systems by adding ...
