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 ...

Putting it simply, Raman spectroscopy involves shining monochromatic laser light onto a sample of material. The molecules in that substance vibrate in response, scattering the light in a unique ...

This new Raman spectrometer system integrates lenses, a diode laser and a diffraction grating—a small thin square-shaped surface that scatters light for analysis—in combination with a camera ...

Nick Stone discusses some of the many ways in which light can be used for diagnostic and therapeutic applications ...

Safe and effective high explosives are critical to Lawrence Livermore National Laboratory's (LLNL) mission of stockpile ...

Raman spectroscopy uses scattered light to identify a substance's chemical ingredients and is one of the most widely used scientific methods in space exploration. It is used for lunar exploration ...

This Raman spectrometer system integrates lenses, a diode laser and a diffraction grating in combination with a camera from a cellphone to record the Raman spectrum. Peaks in the spectrum provide ...
