Abstract

An electromagnetic beam chromatic shifting and directing means for use in reflectively directing a spectroscopic beam of electromagnetic radiation while simultaneously de-emphasizing intensity in a first range of wavelengths, (eg. the Visible wavelengths), and simultaneously relatively emphasizing intensity in another wavelength range, (eg. UV wavelengths).
