SS-Raman spectroscopy employs a swept-source laser, a narrow-bandwidth bandpass filter (BPF), and a highly sensitive point photoreceiver for sample identification. These components enable the ...

Conventional mass spectrometers are typically very large, comparable in size to an oven or refrigerator. By using a technology called a “coded aperture,” the researchers believe they can shrink these ...

CORVALLIS, Ore. – Scientists including an Oregon State University materials researcher have developed a better tool to measure light, contributing to a field known as optical spectrometry in a way ...

The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...
