单色仪-光栅
单色仪光栅标淮产品

单色仪光栅已被优化，更方便与固定入射狭缝、光栅及出射狭缝组合，与传统凹面光栅不同，聚焦不会因为阔度增加移动离开出射狭缝。这因为全息校正把这些数据优化改善定义，全息设的优点在已选择的波长范围内作即时抑制散光像差。

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
