PAV: Protected Aluminum Flat Mirrors
PAV: Protected Aluminum Flat Mirrors
Low power, good reflectivity broadband metal mirror for visible and near-IR; 400 - 800 nm. With > 87% reflectivity from 400 - 800 nm and > 90% average reflectivity up to 10 ?m, these protected aluminum mirrors are the best general-purpose metal mirror for external reflectors and basic light routing at visible and near-infrared wavelengths.
