THE Raman spectrum of water has been studied in ... for the polarisation introduced by the optical train in the glass spectrograph itself, having been made by a previous calibration of the instrument.

A portable Raman analyzer enables remote detection of hydrogen gas at concentrations below 1 part per million, identifying leaks of a few hundred milliliters per minute from several meters away.

The RP-1, SpectraCode's existing point-and-shoot, high-resolution imaging spectrograph, analyzes samples with a monochromatic laser and records their vibrational signatures in the Raman spectrum of ...

An RMS1000 was fitted with an externally coupled 325 nm He-Cd laser for PL characterization, a 638 nm laser for Raman characterization and a CCD camera in a 225 mm spectrograph, as shown in Figure 2.
