6. Metallic mirrors

Metallic mirror coatings are highly reflective over a wide spectral range.

A protective SiO2 layer is applied to the outer reflective metal layer to prevent oxidation and metal degradation.

Mirrors are resistant to external adversity

Wiping with a soft cloth moistened with ethyl alcohol is allowed.
