Metallic Mirror Coatings
Metal mirror coatings are often used in systems where a very broadband reflector or beam splitter is needed. Metal coatings can also be an excellent choice when an economical coating is especially important. Examples of common metal coating applications include telescope mirrors, neutral density filters, and general purpose laboratory mirrors. Metals commonly deposited at ZC&R include aluminum, chromium, silver, gold, and Inconel.
Enhanced First Surface Aluminum
The front surface of the enhanced aluminum mirror coating reflects an average of 93% over the visible spectrum (450-650nm). Back surface reflective aluminum coatings are also available.
Enhanced First Surface Silver
This design is very standard and often uses for demanding telescope and other very high performance imaging applications. Reflectance may be specified for IR wavelengths.
Protected Gold Mirror
The protected gold mirror coating reflects an average of 97% over the spectrum (700-2000nm). This coating can also be used for IR wavelength bands 3-5nm and 8-12nm.
