Abstract: An optical arrangement for use in spectrometry uses a masking device which eliminates unwanted spectral regions prior to optically resolving the unmasked information. The optical arrangement comprises an entrance slit to select incidence spectral energy from an energized source and a concave grating of relatively low dispersion to image the spectrum of the entrance slit onto a stationary mask which simultaneously selects spectral regions of the dispersed incident spectral energy. The selected spectral regions are collimated and recombined and directed onto an Echelle grating to disperse with high resolution the selected spectral regions. A concave mirror focuses the dispersed selected spectral regions into a focal plane of highly resolved spectral energy which can be detected to determine the spectral information coming from the source. The optical arrangement is particularly well suited for use with narrow spectral bandwidth spectral information distributed over a large spectral range. In spectroscopy, desired information very often occupies a tiny fraction of the total spectral information presented to a spectrometer. With this optical arrangement, spectral information can be selected from a much broader band spectral information and collected with high resolution on a small curvilinear portion of the output focal plane. The arrangement is particularly useful for absorption, light scattering or emission spectroscopy. It provides a stable mechanical design making it less sensitive to vibration. Manufacturing mechanical tolerances are also less restrictive.

Abstract: The disclosure relates to dispersive lenses and spectrometers for performing a method of focusing holograms in which the hologram that is placed on a spherical surface plays an active part in the focusing. Contrary to focusing methods of the prior art wherein the focusing locus is determined as a function of the tangential object and image focal lines, the described invention determines the focusing locus as a function of the sagittal object and image focal lines. A stigmatic mounting (i.e. a perfect mounting to eliminate odd order abberations) results in the tangential and sagittal focal lines being identical. The description sets forth equations to cover all points in the focusing plane by suitable action of the phase variations generated by the hologram. The diffraction grating used is reflective and includes a fixed entrance slit and at least one fixed exit slit.
