A reflection of Brian Bauman (left), the space hardware principal optical engineer and inventor of the monolithic telescope and Frank Ravizza, the space hardware optical engineering lead, is seen on the primary mirror surface on a flight-ready 175-millimeter aperture monolithic telescope. Additionally, Ravizza is seen holding a 25-millimeter aperture monolithic optic. The ease of handling showcases the robust design incorporated in all monolithic telescopes.
