Focusing (Concave) Mirrors,Curved Mirror

Focusing Mirrors, or Concave Mirrors, are often used in applications that require light collection. Focusing Mirrors are also ideal for use in imaging systems, as they do not introduce chromatic aberration. As light strikes the surface of a Concave Mirror, the mirror’s surface profile causes the reflected light to focus to a point.

Wide selection of various size round, rectangular, spherical mirrors protected gold, silver or aluminium.

Metallic mirrors are widely used due to a moderate level of reflection over a very broad spectral range. Protected gold coatings have the highest reflectance in IR, silver is most efficient in VIS, while aluminium is economical reflector over entire 300-IR region.

A layer of dielectric material protects the coatings of the mirrors in order to make them durable. Enhanced metallic coatings provide greater reflection across the operating bandwidth.

Metal coated mirrors are made of protected UV Enhanced Aluminium, Aluminium (Al), protected Gold (Au), protected Silver (Ag) coatings.
