A device for detailed measurement of diffraction grating efficiencies and over-all performance in the VUV has been designed and constructed at the Naval Research Laboratory. The system employs semiautomated mechanisms to scan the face of the grating with a narrow monochromatic beam, and an efficiency map of the grating surface is produced on a strip chart recorder. Grating efficiency in the various diffracted orders and intensity of light scattered between orders may also be measured. A unique feature is the ability to determine the angle and effectiveness of grating blaze and variations in blaze under different conditions of illumination.
海军研究实验室设计并制造了一种用于详细测量真空紫外（VUV）区域衍射光栅效率及整体性能的装置。该系统采用半自动机构，用窄单色光束扫描光栅表面，并在带状记录器上生成光栅表面的效率图。还可测量各衍射级次的光栅效率以及级次间散射光的强度。一个独特的功能是能够确定光栅闪耀的角度和效率，以及在不同照明条件下闪耀的变化情况。
