Abstract
We have been developing ultra-lightweight Wolter type-I X-ray telescopes fabricated with MEMS technologies for GEO-X (GEOspace X-ray imager) which is a small satellite mission to perform soft X-ray imaging spectroscopy of the entire Earth’s magnetosphere. The telescope is our original micropore optic which possesses lightness (~5 g), a short focal length (~250 mm), and a wide field of view (~5 deg x 5 deg) and can satisfy stringent limits on mass and size. We report on fabrication methods, their optimization, subsequent imaging performances of the telescope, and results of environmental tests.
