1. An adaptive illuminator of an adaptive illumination system, the adaptive illumination system comprising a light source, a collector lens, the adaptive illuminator, a focusing lens, and a target plane, the adaptive illuminator comprising:
a first optical element comprising negative optical power;
a second optical element comprising positive optical power; and
a third optical element comprising positive optical power; wherein the first optical element is moveable along an axis along which light is emitted from the light source, wherein the second optical element and the third optical element are immoveable along the axis, wherein light from the light source travels directly from the first optical element to the second optical element and from the second optical element to the third optical element, and wherein the adaptive illuminator receives a semi-collimated input beam and outputs a converged light cone.
