Overview: Metal Coated Concave Mirrors (Metal Coated Focusing Mirrors) are
characterized by one concave surface with metallic high reflection
coating. The reflective coating allows focusing of a light beam.
Most common coating materials include aluminum Al, gold Au or
silver Ag. A requirement for a focusing mirror is when no chromatic aberration
is allowed in a broad spectral range. Yet another common use case
is tightness optimization of an optical system. Concave mirrors can be used similarly to focusing lenses. Type of
image created by a focusing mirror depends on radius of the concave
surface as well as on the distance from an object to the mirror.
