Product Details

concave spherical mirror

Concave Spherical Mirrors have a polished, spherical surface, metallic coating, and curved back. Each mirror has a positive focal length, and will focus incident light. All first surface Concave Spherical Mirrors feature a glass substrate.

The Enhanced Aluminum coating is ideal for applications in the visible spectrum, while Protected Gold provides excellent reflection throughout the NIR, MWIR

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.
