Special Features

  • Unique enhanced multi-layer mirror coatings made from precise layers of aluminum SiO2 (quartz) TiO2 (titanium dioxide) and SiO2 (silicon dioxide). Reflectivity is fairly flat across the spectrum optimizing it for both imaging and visual observing.|Multi-layer anti-reflective coatings made from precise layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide). Hafnium—a rare element that costs nearly $2 000 per kilogram—gives us a wider band pass than the titanium used in competing coatings.|High-transmission water white glass is used instead of soda lime glass for the corrector lens. Water white glass transmits about 90.5% of light without anti-reflective coatings; that's 3.5% better than uncoated soda lime glass. When water white glass is used in conjunction with StarBright XLT's anti-reflective coatings the average transmission reaches an astonishing 97.4.
