Coating TypesReflectivity
 Protected AluminumRavg > 87% from 400nm to 800nm
VIS Enhanced AluminumRavg > 93% from 450nm to 750nm
UV Enhanced AluminumRavg > 86% from 250nm to 400nm

Metallic reflective coatings are delicate and require care during cleaning. Clean and dry pressurized gas can be used to blow off loose particles, then clean, deionized water, a mild detergent can be used. Gentle cleaning with a swab is recommended
