Protective Aluminum Mirrors
The key to protecting aluminum mirrors is to reduce oxidation, prevent scratches, and enhance durability while maintaining high reflectivity. Aluminum reacts easily with oxygen and water vapor in air to form aluminum oxide (Al₂O₃), resulting in a decrease in reflectivity (especially in the UV and visible wavelengths). Solution: protective coating (transparent dielectric protective layer on the surface of aluminum).

Overview
The key to protecting aluminum mirrors is to reduce oxidation, prevent scratches, and enhance durability while maintaining high reflectivity. Aluminum reacts easily with oxygen and water vapor in air to form aluminum oxide (Al₂O₃), resulting in a decrease in reflectivity (especially in the UV and visible wavelengths). Solution: protective coating (transparent dielectric protective layer on the surface of aluminum).
Key Features
Protective coating material: MgF2; Applicable bands: UV-VIS (optimal); High hardness, good transmittance in the UV, but general resistance to moisture and heat (thickness about λ/4, λ=550nm). Protective coating material: SiO2; Applicable bands: VIS-IR; Chemically stable and resistant to wiping, but with high UV absorption (thickness needs to be optimized). Protective coating material: Al2O3; Applicable bands: Broadband; Prepared by atomic layer deposition (ALD), they are ultra-thin and dense, but costly.
