概要（Overview）

The Xradia Ultra family comprises of Xradia 800 Ultra, operating at 8 keV photon energy, and Xradia 810 Ultra, operating at 5.4 keV. In general, lower energy X-rays are absorbed more strongly and therefore will provide you with higher contrast for most materials. Thus, as long as transmission remains sufficient, you will experience resulting image quality and/or throughput that are greatly improved with Xradia 810 Ultra. For materials of higher density, or thick specimens Xradia 800 Ultra delivers higher photon energy for (typically) more transmission.
