Development of Multi-Layered Aspheric Mirrors for InternationalX-Ray Observatory

用于2015年发射的新一代X射线天文卫星ASTRO-H的硬X射线望远镜(HXT)的制作已经完成，该望远镜采用深度梯度铂碳多层圆锥镜。此外，在ASTRO-H项目之后，下一代硬X射线望远镜的非球面复制模具的超精密加工已经通过具有50 nm P-V精度的全自动抛光工艺链进行了演示。

Fabrication of a hard X-ray telescope (HXT) with depth graded Pt/C multilayered conical mirrors has been completed, for the next generation X-ray astronomical satellite ASTRO-H to be launched in 2015. Furthermore, ultra-precision finishing of aspheric replication molds for next generation hard X-ray telescopes after the ASTRO-H project has been demonstrated by a fully automated polishing process chain with50 nm P-V accuracy.
