consists of a laser source, a sample illumination system, a spectrometer, and a detector. The laser light interacts with the sample, and the scattered light is collected and analyzed by the ...

Raman spectroscopy is an analytical technique which can be used to identify the pigments used in a painting. A low powered laser is directed onto the surface of an object or painting and the light ...

Researchers have developed a new portable Raman analyzer that can accurately measure very low concentrations of hydrogen gas ...

It combines the nanoscale spatial resolution of atomic force microscopy with the chemical analysis capabilities of infrared spectroscopy ... a pulsed laser source, together with optics for ...

Researchers have developed a new technique that can detect the presence of micro- and nanoplastics in clear body fluids. They ...

When an intense light source, such as a laser, is used to analyze them ... analyzes samples with a monochromatic laser and records their vibrational signatures in the Raman spectrum of the ...

Microplastics and the much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in ...

Raman lasers were very important in the early days of laser spectroscopy ... it could be useful as an efficient high-power tunable source in the yellow band by using a tunable green pump, allowing ...

In this case, Raman spectroscopy uses Raman scattering, a process that sees how light interacts with molecular vibration. This happens at a different frequency than the laser. Through this, the ...
