Kirkpatrick-Baez (KB) and Lobster Eye (LE) Optics for Astronomical and Laboratory Applications
(a) The X-ray focal image of the MINI LE SCHMIDT module showing the main intensity to be inside the main focal spot. The intensity gain achieved is 570 (for 8 keV X-ray tube and only part of the LE module active due to the high energy of X-ray photons—note that this module has been designed for energy of 2 keV). (b) The focal plane image for the LE test module. The measured gain is 500.
