Concave Mirror

Spherical Concave Mirror             

After metal or dielectric high reflection coated on the concave substrates, it's a concave mirror. Concave mirror can be focus the light beam or imaging as a lens. The focal length of concave mirror is half of the curvature radius.              

It can be widely used in optical equipment.
