Did You Know?

In optical systems, mirror coatings are essential for controlling light reflection. Unlike household mirrors, which have coatings on the back, optical mirrors feature front-surface coatings to prevent image distortion. These coatings are typically made from metals like aluminum, silver, or gold, each offering unique reflective properties. Aluminum: Commonly used for visible and ultraviolet applications, providing moderate reflectivity. Silver: Offers high reflectivity across the visible spectrum but may tarnish over time. Gold: Ideal for infrared applications due to its excellent reflectivity in the infrared range. To enhance durability and performance, these metallic coatings are often protected with dielectric layers, such as silicon dioxide. This combination ensures high reflectivity and resistance to environmental factors. The choice of coating depends on the specific wavelength range and application requirements, making mirror coatings a critical component in precision optics.
