Silicon Pore Optics

The Silicon Pore Optics consist of single crystal silicon mirrors to focus X-rays. Silicon Pore Optics use the fact that standard double sided polished silicon wafers from the semiconductor industry have excellent properties for making X-ray mirrors. By using standard industry tools, cosine can shape the best quality silicon wafers and process them to form mirror segments.

This technology breaks the traditional assumption that thinner mirrors have to result in less imaging quality. By making use of the inherent stiffness of porous structures, very thin mirrors can be produced in a solid structure.

The advantages of SPOs of cosine are the

  • large surface area
  • low mass
  • high accuracy
  • low cost
