Parks Parabolic Primary Mirrors (Pyrex) 6" f/8 Mirror

Parks parabolic primary mirrors are made of fine annealed Pyrex, with a full 1:6 ratio of thickness to diameter. Individually hand-figured by skilled opticians, each mirror will produce a good diffraction ring with no turned edges or edge zones. The optical surface will exhibit straight Ronchi bands from edge to edge as seen in the sensitive double-pass auto-collimation test. Aluminized and silicon monoxide overcoated for long-lasting performance.
