方孔微通道板（MCP）的X射线光学的“龙虾眼”的几何形状已经常在文献中描述。我们现在已经研究了径向通道填充几何形状的使用，在MCP对塌陷到正确曲率半径的情况下，该几何形状可以形成对Wolter I型掠入射X射线光学器件的圆锥近似。这种光学器件可以提供具有非常低质量的大的有效面积，并且可以理想地适用于诸如行星成像X射线荧光的应用。我们在这里提出的第一个这样的光学，由Photonis SAS，法国制造的X射线照明的结果。
Square-pore microchannel plate (MCP) X-ray optics of the “lobster-eye” geometry have frequently been described in the literature. We have now investigated the use of a radial channel packing geometry which, in the context of an MCP pair slumped to the correct radii of curvature, can form a conic approximation to the Wolter Type I grazing incidence X-ray optic. Such an optic can provide a large effective area with very low mass and may be ideally suited for use in applications such as planetary imaging X-ray fluorescence. We present here the results of X-ray illumination of the first such optic, fabricated by Photonis SAS, France.
