Dielectric Coatings

Dielectric coatings” are coatings found on roof prisms and they increase light reflectivity. These type of coatings can deliver reflectivity from roof prism surfaces of more than 99% (claimed by manufacturers), which is incredible compared to the reflexivity of an aluminum mirror coating, which is 87% to 93% and the 95% to 98% of a silver mirror coating.
