Wavelength-dispersive spectrometers employ diffraction by a single crystal to separate characteristic wavelengths emitted by the sample. Today, nearly all commercially available X-ray spectrometers use the fluorescence excitation method and employ a sealed X-ray tube as the primary excitation source. The ...

For comparison, measurements of all samples and elements using a Philips PW 1480 wavelength-dispersive spectrometer were also performed. Differences in the RSD values obtained using the two spectrometers were not significant for the main elements, Cu and Zn in brass and Cr, Fe and Ni in ...
The present invention is a dispersive, diffraction grating, NIR spectrometer that automatically calibrates the wavelength scale of the instrument without the need for ext
Waveguide-based spectrometers capable of separating light signals at different wavelengths have already been established as one of the key technologies in wavelength division multiplexed telecommunications networks (wavelength multiplexers and demultiplexers, add-drop filters, channel monitors, etc.).
