Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of utmost importance in applications ranging from environmental monitoring and ...

Researchers have developed a spectrometer capable of applications ranging from disease detection to astronomical observations. Spectrometers have been around for centuries, but this is a game-changer.

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Design and working principle of the miniaturized UV spectrometer. (a) Conceptual schematic of the GaN-based cascaded photodiode architecture. (b) Device structure consisting of two vertically cascaded ...

Red laser light is coupled into a spectrometer chip with an optical fiber from the left. The light travels along the chip until it is scattered out the the top in a waveguide section on the right.

“Spectrometers are critical tools for helping us understand the chemical and physical properties of various materials based on how light changes when it interacts with those materials,” says Brendan O ...

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...

Leveraging its expertise in fields such as integrated circuits for telecommunications, France-based research institute CEA-Leti says it is “driving innovation in cutting-edge applications”. One of its ...

Researchers are designing new ways to make spectrometers that are ultra-small but still very powerful, to be used for anything from detecting disease to observing stars in distant galaxies.

(Nanowerk News) Spectrometers are technology for reading light that date back to the era of famed 17th-century physicist Isaac Newton. They work by breaking down light waves into their different ...
