1. A light expander/contractor device comprising:
a faceted quartz structure comprising a lateral surface communicating with a light processing surface at one end and communicating with a planar surface at an opposed end;
the light processing surface comprising an initial surface extending from the lateral surface substantially parallel to the planar surface and having a distal end spaced from the lateral surface, the light processing surface further comprising multiple levels of facets comprising interfaces selected from the group consisting of quartz-air interfaces and quartz-vacuum interfaces;
each level of facets comprising (a) a proximal facet surface relative to the lateral surface, the proximal facet surface extending away from the initial surface and toward the lateral surface at a 45° angle relative to the initial surface to communicate with (b) a facet planar surface spaced apart from and parallel to the initial surface to communicate with (c) a distal facet surface adjacent and substantially parallel to the proximal facet surface.
