Metallic mirrors (aluminum, silver, gold; protected; enhanced)
Metal mirrors utilize aluminum, silver, or gold as functional layers to achieve high-efficiency reflection in specific wavebands through vacuum evaporation processes. The protective type employs silicon oxide/aluminum nitride composite encapsulation layers to isolate environmental erosion, while the enhanced type improves peak reflectivity and expands bandwidth via dielectric film stacking. Substrates accommodate materials including optical glass and metals, supporting high-precision surface shaping and active cooling integration for precision optical applications.
