Shanghai Optics is a custom optics manufacturer with over 55 years of optics manufacturing experience. We supply high precision Ultra-Broadband Metallic Mirrors according to customers’ specifications. These mirrors provide a high reflectance over a very broad spectral bandwidth. They are manufactured by coating first with a reflective metal film and then with a dielectric overcoat for protection and enhancement of the reflectivity.
Coatings offered include aluminum, silver and gold. Each has a different spectral characteristic as shown in the curves. Aluminum provides a good general purpose visible range mirror. Silver has a very high reflectance over the visible and near infra-red range and gold is the preferred coating for infra-red applications at wavelengths greater than 2 microns.
