Note:
(1)all imaging gratings are holographically exposed
blazed- sawtooth profile
ion- ion etched sawtooth profile
sine- sinusoidal profile
(2)the efficiency maximum of holographically blazed gratings can vary between 210 and 250nm
(3)adaptable to experimental conditions
(4)given thickness is the center thickness
preferred materials are NBK7 and ZKN7
l.g. - lateral grinded
(5) monochromator difference D = b-a
(6) D= 106 cos b/(LB*G) [nm/mm]
(7) for entrance slit width 50µm
(8) see drawing
(9) related to shortest waveleng
