Comparison between experimentally measured first-order efficiencies by Jark (1992 ) and those calculated rigorously with the real groove profile of the 1220 mm−1 laminar grating versus photon energy in in-plane diffraction. The grating was operated in the fixed-focus condition, with constant ratio sinϕ/sinθ = 2.25. |
