Paper Abstract

A post-polishing experiment was conducted to see if the wavefront performance of a volume-phase holographic grating with thin substrates could be improved. The ability to postpolish the grating assembly after production of the grating could lead to much improved imaging performance. The ability to use lower quality substrates can reduce the upfront cost and risk involved with using high performance substrate units.
