Abstract
A monochromator having a fixed inlet slot, a holographic grating carried on a concave turnable support, and a fixed outlet slot, the support surface of the holographic grating being a concave portion of a toroidal surface, taken at the outer periphery of the toroid, and symmetrically disposed with respect to the equatorial plane of the toroid, the equatorial plane also containing the point sources for recording the holographic grating.
