讨论了建立高分辨率真空紫外单色仪的可能性；选择离机鹰式安装为最合适的安装方式。考虑到离平面设置引起的所有光学限制，在以下条件下，对离平面Eagle安装中光栅的分辨能力进行了数值计算：3 m凹光栅(5- × 3-in；规则区域)30,000线/英寸。或者15000行/英寸。， 0 ~ 5800 A为一阶，入口狭缝距罗兰平面6 cm。为了紧凑，在扫描系统中选用了Bair等人介绍的连杆机构，并给出了3米真空单色仪的初步设计示意图。因此，建议在构建高分辨率真空紫外单色仪时使用飞机外的Eagle安装。
The possibility of constructing a high-resolution monochromator for the vacuum ultraviolet is discussed; off-plane Eagle mounting is chosen as the most suitable one. Considering all optical restrictions arising from an off-plane setting, the resolving power of the grating in the off-plane Eagle mounting is calculated numerically for the following conditions: 3-m concave grating (5- × 3-in. ruled area) with 30 000 lines/in. or 15 000 lines/in., 0 to 5800 A in the first order, and distance of the entrance slit from the Rowland plane 6 cm. In order to have compactness, a link mechanism introduced by Bair et al. is chosen in the scanning system and a tentative design of a 3-meter vacuum monochromator is shown schematically. As the result, it is recommended to use the off-plane Eagle mounting in constructing a high-resolution monochromator for the vacuum ultraviolet.
