(a) McStas simulation of imaging an aperture with \(A_1\) = 2 mm diameter using a CRL and a FZP at 12.5 Å   wavelength with 10% bandwidth and distances of \(L_1\) = \(L_2\) = 18 m. The contribution due to different wavelengths are color-coded. (b) Image of a 2 mm diameter \(A_1\) pinhole formed by the FZP at 12.5 Å  neutron beam at 10 \(\%\) bandwidth on an imaging plate. The exposure time was 2400 s. (c) Scattering pattern produced by a \(3.5\,{\upmu }\hbox {m}\) period silicon grating with the FZP in a focusing SANS geometry in an imaging plate (top) and the PSD detector (bottom). The exposure times were 2100 s and 300 s respectively.
