Kirkpatrick-Baez (KB) and Lobster Eye (LE) Optics for Astronomical and Laboratory Applications
Upper panel: simulated LE MCP cm optic performance at a wavelength of 121.6 misalignments have been modelled by introducing an additional tilt to each and direction of each tilt is taken from a Gaussian distribution with a FWHM X-axis and 1.70° in the y-axis. The resulting focal spot has a FWHM (horizontal) and (vertical). Lower panel: laboratory measurements. Cross-arm structures characteristic of a square-pore MCP optic are clearly visible. The FWHM of the central focus is 2.38 deg (horizontal) ×2.70 deg (vertical) (Bannister et al., 2007 ).
