Description: Spherical mirror
Spherical Mirrors: A mirror whose reflective surface is part of a spherical surface is called a spherical mirror. Spherical mirrors are classified into two types: convex mirrors and concave mirrors. A spherical mirror that uses the inner surface of the sphere as the reflective surface is called a concave mirror, while one that uses the outer surface is called a convex mirror. Reflective coatings are typically applied to meet specific reflectivity requirements. Common reflective coatings include UV-enhanced aluminum, protected aluminum, silver, gold, and dielectric reflective coatings.
