Round or rectangular shape mirrors with flat or spherical surface, coated with protected gold, protected silver or protected aluminum. 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, protected silver is the most efficient in VIS, while protected aluminum is an economical reflector over entire 300nm-IR range. The top layer of dielectric material protects the metallic coatings and makes metallic mirrors durable and stable within long term of operation. Enhanced metallic coatings with greater reflection across the specific spectrum range are available under custom request. The coatings for metallic mirrors are deposited using thermal evaporation and electron evaporation technologies. Most of the mirrors are available ex-stock for fast off-the-shelf delivery.
