The roots of dispersive infrared spectrometry trace back to the early 20th century. It was here that initial advancements in infrared physics initiated a transformation of
Thus linear dispersion, the separation of light by position instead of angle, is most useful in the lab. For a spectrometer with focal length f, this "spreading of the rainbow" is computed by recognizing that for a
Unlike the single grating Czerny–Turner configuration spectrometers, a super-high spectral resolution optical spectrometer with zero coma aberration is first experimentally
WDS (Wavelength Dispersive X-ray Spectroscopy) is a complementary technique to EDS (Energy dispersive X-ray Spectroscopy) analysis on a SEM. Both
