Kirkpatrick-Baez (KB) and Lobster Eye (LE) Optics for Astronomical and Laboratory Applications

Figure 57

Upper panel: simulated LE MCP 𝑓 = 3 . 8  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 2 . 6 4 ± 0 . 2 (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 [75]).
