A Sc-Si multilayer coating was applied to a replica of the 3600 groove/mm grating, developed for the SO82A spectroheliograph that flew on the Skylab mission, for the purpose of enhancing the normal-incidence efficiency in the extreme-ultraviolet region. The efficiency, measured at an angle of incidence of 6 degrees with synchrotron radiation, had a maximum value of 7.2% at a wavelength of 38 nm and was a factor of 3 higher than the efficiency of the gold-coated Skylab grating. The measured efficiency of the Sc-Si grating was in good agreement with the efficiency calculated by use of the modified integral method.
一种Sc-Si多层涂层被应用于每毫米3600条刻槽光栅的复制品上，该光栅是为搭载在天空实验室任务中的SO82A太阳单色光照相仪研制的，目的是提高极紫外区域的正入射效率。在6度入射角下用同步辐射测量的效率，在波长38纳米处有一个7.2%的最大值，比涂金的天空实验室光栅的效率高3倍。Sc-Si光栅的测量效率与用改进的积分方法计算的效率吻合良好。
