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.
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.
