|Mirror coatings are designed to achieve the maximum
reflectivity over the widest spectrum of wavelengths.
There is always a trade off, in that the wider the range of operating wavelengths, the lower the overall reflectance.
Protected Silver has a similar performance to Gold coating in the near infra red, but the visible performance is better for silver. Gold coatings can be used at Terahertz frequencies.
Protected Silver is more durable.

Enhanced coatings for specific wavelengths such as 633nm, see below, or 10.6 microns wavelength such as our MaxR coating.
