PG&O’s new fabrication capability utilizes several infrared materials, including calcium fluoride (CaF2), magnesium fluoride (MgF2), silicon (Si), germanium (Ge), and zinc sulfide (ZnS) to deliver optically-clean, polished IR materials. The new optics operate from 0.75 µm, the near-infrared (NIR), out to15 µm, the longwave-infrared (LWIR) spectrum.
