Gold Coating Plano Optical Mirrors
Plano Optical mirrors can be manufactured in almost any shape: round, rectangular, elliptical, or any other shape including cut-outs and drill holes. Holes may also be drilled at an angle to the surface normal.
The design of the mirror coating depends on the technical and economical requirements of the application. We offer dielectric coatings and metal coatings with protective overcoat.
Metal coatings may be aluminium, silver or gold.
Product Code:GA-GOM
GiAi offers various Optical mirrors with metal coating. Metal coatings may be aluminium, silver or gold.
Protected aluminium is economical, environmentally robust and reflects from the UV to the mid-IR. The reflectivity is not as high as for silver or gold and has an absorption dip from about 750-850nm.
Protected silver exhibits higher reflectivity than aluminium but does not extend as deeply into the UV. Silver is environmentally not as robust as aluminium and will tend to darken at the edges with time.
Protected gold is the coating of choice for IR applications. This coating has the highest IR reflectivity and is environmentally very stable.
