Metallic Mirror Coatings


Abrisa Technologies can deposit a wide variety of precious and non-precious metals onto glass substrates depending upon the application requirement. 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 by Abrisa Technologies include aluminum, chromium, silver, gold, and Inconel. Other metals, semi-conductors, and alloys are available, contact our ZC&R Coatings for Optics division for more information: (800) 426-2864.


Standard mirror coating specifications are detailed below:

  • Protected Aluminum – Wavelength range (400 – 700nm) and reflects an average of > 85% rover the visible spectrum. Used for applications in the visible or near-infrared.
  • Enhanced Aluminum – Wavelength range (450 – 650nm) and provides >93% reflectivity. A multi-layer film of dielectrics on top of the aluminum enhances the reflectance in the visible and ultraviolet regions.
  • Protected Gold – Wavelength range (700 – 2000nm) and reflects an average of 97%. This coating is best-suited for applications requiring high reflectance in the near-infrared and infrared regions. IR wavelength bands 3-5nm and 8-12nm.
  • Protected Silver – Wavelength range (500 – 800nm) and provides >98% coating offers excellent reflectivity in the visible and infrared regions. It is used for broadband applications. Best suited in low humidity environments to reduce tarnishing.
