Key Features

Broad spectral range; low sensitivity to incidence angle and polarization; low cost; non-durable; relatively low reflectance; low laser-damage threshold. Aluminum is the most widely used metallic reflective coating, offering high reflectance from near-ultraviolet to near-infrared at low cost. Silver reflects more strongly than aluminum in visible and near-infrared bands, but the source states that it oxidizes rapidly in air and darkens, quickly degrading coating performance and hardness. Gold coatings offer good consistency and high reflectance in near-, mid-, and far-infrared bands, effectively controlling thermal radiation, but are soft, easily scratched, expensive, and require particular care during cleaning.
