Primary mirror & diagonal mirror anti-reflective film repair

Telescope Reflector Recoating

Overview

The primary and diagonal mirrors used in reflective astronomical telescopes are subject to gradual degradation from rain, condensation, dirt and mold.
Geomatec can re-apply anti-reflective film to damaged primary and diagonal mirrors, making them function like new.
Coating can be applied to primary mirrors (concave mirrors), Newtonian secondary mirrors (flat mirrors), Cassegrain secondary mirrors (convex mirrors), and mirrors of all other shapes.
