Raman spectroscopy is a widely used measurement technique for this purpose. When a laser beam is projected onto molecules, ...

Researchers at Umeå University have recently developed a highly sensitive method for detecting bacterial spores — tough ...

The laser light interacts with the sample, and the scattered light is collected and analyzed by the spectrometer, producing a Raman spectrum that represents the molecular fingerprint of the sample.

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 ...

Raman Spectroscopy Laser Systems (785nm, P>500mW) High performance diode laser system (single frequency, single mode, up to 1 W, 785 and 980 nm + other wavelengths on request) Single mode fiber ...

When laser spectroscopy is combined with microscopy, spatial variations of the chemical compositions of both organic and inorganic samples can be precisely determined. One of the spectroscopic ...

In Raman spectroscopy, a laser is used to irradiate a sample. Almost all of the light is scattered in an elastic manner, meaning no change in energy occurs. However, a small percentage of light is ...

This article explains the "Raman Concatenation", a measurement approach that can overcome several trade-offs. In general, fluorescence impacts many Raman measurements, necessitating the adoption ...
