Toroidal concave grating: Such gratings correct for the astigmatism inherent in a grazing incidence mount by having different radii of curvature R for the dispersion (or meridional) plane and the plane perpendicular to it, the sagittal :// The spherical laminar gratings have been replaced by paraboloidal gratings. The substrates of the new gratings have measured slope errors less than :// Concave holographic gratings function as both a dispersing and focusing element for monochromators. These gratings contain two focusing elements: the substrate, and the groove curvature. As a result, an instrument designer can replace a lens system by using concave gratings, leading to a reduction of optics in a system, and thus, :// USA USA USA USA US A US A US A US A US A US A US A US A US A US A US A US A Authority US United States Prior art keywords slit grating mirror plate rowland circle Prior art date Legal status (The legal status is an assumption and is not a legal ://

  Classically ruled gratings may be plano or concave and possess grooves each parallel with the next. Holographic grating grooves may be either parallel or of unequal distribution in order that system performance may be optimized. Holographic gratings are generated on plano, spherical, toroidal, and many other :// EPB1 EP EPA EPB1 EP B1 EP B1 EP B1 EP EP EP EP A EP A EP A EP B1 EP B1 EP B1 Authority EP European Patent Office Prior art keywords grating spectrometer points focal curve characterized Prior art date Legal status   Astigmatism is unavoidable in conventional gratings. However, it can be reduced to a certain extent even with spherical concave gratings when ruled or recorded to introduce the right amount of varied line spacing and/or curved grooves [lo, Resolving Power first "Offers and up-to-date assessment of the entire field of diffraction gratings, including history, physics, manufacture, testing, and instrument design.
