在BESSY II储存环上，联邦物理技术局（PTB）将操作专门用于辐射测量的插入装置。附加光束线系统的一个分支将配备一个掠入射单色器，如此处所述。单色器的概念是基于一个平面光栅在平行光操作;因此，精确的聚焦保持所有光子能量，而不管在光栅的角度设置。单色器已被优化为小的高阶透射率和高功率吞吐量，所需的辐射测量应用在宽光子能量范围从20 eV到1900 eV。
At the BESSY II storage ring, the Physikalisch-Technische Bundesanstalt (PTB) will operate insertion devices dedicated to radiometric use. One branch of the appendant beamline system will be equipped with a grazing-incidence monochromator, described here. The monochromator concept is based on a plane grating operated in parallel light; therefore exact focusing is maintained for all photon energies irrespective of the angular setting at the grating. The monochromator has been optimized for small higher-order transmittance and high power throughput, as required by radiometric applications in the wide photon energy range from 20 eV to 1900 eV.
