In addition, because Raman lasers require an initial laser input, they are most effective as a wavelength shifter. Raman lasers were very important in the early days of laser spectroscopy ...

Schematic representation of Raman spectroscopy. After the sample (molecule) is exposed to an intense beam of monochromatic light in the frequency range of visible, near-infrared or near-ultraviolet ...

In general, fluorescence impacts many Raman measurements, necessitating the adoption of longer excitation wavelength (lower photon energy) lasers to prevent the fluorescence signal from ...

A typical Raman spectroscopy configuration requires a laser light source with a narrow spectral width and high wavelength stability, a spectrometer to disperse Raman scattered light, typically a ...

Unlike erbium-doped fiber amplifiers (EDFAs), which boost wavelengths in the 1530-1610 ... lengths of signal-transmitting fiber. A Raman pump laser is typically stationed at the end of a fiber ...

When selecting a Raman spectrometer, the primary consideration should be the wavelength of the laser light that will be utilized to excite the sample. Since the technique is related to the vibrational ...

Each module includes an optical interface, laser excitation, Raman software and spectrometer. Modules are offered with a range of laser wavelengths and can be used together for the ultimate in ...

Advanced imaging capabilities make the new Thermo Scientific™ DXR3 Raman Microscope quicker with DynaCal Automatic X-axis Calibration that eliminates manual calibration and instant visual information ...
