X-Ray Pore Optics Technologies and Their Application in Space Telescopes

Figure 7

(a) Silicon Pore Optics are made from commercial high-quality 12 silicon wafers which are diced into plates. (b) The plates are ribbed (reflecting surface pointing downwards). The 0.17 mm wide ribs have a pitch of 1 mm and the membrane is 0.17 mm thick. The plates are then wedged along the rib direction (not shown) and a patterned iridium coating is applied on the reflective surface (c). The pattern keeps the areas free where the next plate will be bonded. The plate shown has dimensions of 66×66 mm2 and a thickness of 0.775 mm. Photographs courtesy of Micronit (b) and DNSC (c).
