Three components make up the StarBright XLT: (1) multi-layer mirror coatings comprised of quartz, titanium dioxide, and silicon dioxide, (2) multi-layer anti-reflective coatings made from magnesium fluoride and hafnium dioxide, and (3) high-transmission white water glass within the corrector lens. The result? An outstanding 97.4% average light transmission for impressive resolution of detail!
