Our superior quality elliptical secondary mirrors are made of precision annealed Pyrex blanks, ground to the exact minor axis dimension. All secondary mirrors are made by our own optician, providing complete control of quality from start to finish.

All AstroSystems secondary mirrors are coated with enhanced aluminum, giving 95-96% reflectivity and long coating life. Superior performance for new or retrofitted telescopes.
