It is shown that grisms, a grating and prism combination, are a
simple way to achieve chromatic control in 3D multi-plane imaging. A pair
of grisms, whose separation can be varied, provide a collimated beam with
a tuneable chromatic shear from a collimated polychromatic input. This
simple control permits the correction of chromatic smearing in 3D imaging
using off-axis Fresnel zone plates and improved
