摘要：

The reflectivity of commercially available vacuum-evaporated platinum mirrors in photon energy was measured from 1.8-8 keV. The measured reflectivity was compared with that calculated using a graded refractive index model. For the two mirrors measured, assuming an rms surface roughness of 1.6 and 3.4 nm gave good fit of the measured to calculated reflectivity. These values are almost identical to the roughness measured by scanning tunneling microscopy. Using this model, the reflectivity of conventional vacuum-evaporated platinum mirrors in the few-keV range could be explained.
