…profile in the short axis, and a "top hat" (super Gaussian) profile in the long axis. Top hat refers to a beam intensity cross section with an extended central plateau that falls off near the edges. One way to transform this into a uniform intensity distribution is a cylinder lens homogenizer, consisting…

…in each axis. note, for each rotation of the drum, the beam profile is measured in two different planes, namely, where the knife edges cut the beam nearer the focusing lenses, and where they cross the beam nearer the detector. in operation, the diffraction limited, precision focusing lens assembly first…
…detector by a special electrostatic lens that maps the velocity of the ion, independent of its position of formation [1]. This special feature allows very good kinetic energy resolution ( E/E ~ 2%). In the experiment, a pulsed supersonic jet of OClO is directed along the axis of a time-of-flight spectrometer…

…to move most lenses or work pieces, so the primary benefit of galvanometer scanning systems is speed. However, as the aperture of a scan lens increases, the size of the scan mirrors gets bigger, and mirror mass increases with the cube of aperture. Heavier mirrors can't be moved as fast as lighter mirrors…
