The Rowland circle mounting for scanning VUV monochromators with concave blazed diffraction gratings can be adapted so that the operation is always on-blaze; that is, the monochromator always operates at maximum efficiency. In principle, this adaptation works at any angle of incidence, but in practice only grazing incidence monochromators are practical. The scanning range of such a monochromator is less than for a conventional monochromator but can be extended by storing gratings with different groove densities on a carousel and rotating them into position as necessary.
用于扫描带有凹面闪耀衍射光栅的真空紫外（VUV）单色仪的罗兰圆装置可以进行调整，以使操作始终处于闪耀状态；也就是说，单色仪始终以最高效率运行。原则上，这种调整在任何入射角下都有效，但实际上只有掠入射角单色仪才可行。这种单色仪的扫描范围比传统单色仪小，但可以通过在转盘上存储具有不同刻线密度的光栅并根据需要将它们旋转到合适位置来扩展扫描范围。
