Abstract
Standard diffractive estimates based on the system f/# were at odds with geometric predictions concerning beam footprint size at a relayed pupil image plane due to an object point at infinity. The reason for this was that the relay optic was well within the defractive depth of focus of an intermediate star image. This invalidated geometric predictions for the system f/# and the location and size of the system impulse response. Accurate predictions emerged when Fourier transforms of the highly apodized planar wavefront incident on the relay optic were calculated.
