Mirror Materials

  • Dielectric

Custom dielectric mirrors can be manufactured when you are aiming for high reflection at specific wavelength or angles of incidence. The advantages of dielectrics are they are tough and can offer higher reflectivity then metals at specific wavelengths and angle of incidences. It is also possible to cut down the reflectivity of other wavelengths simultaneously acting as a filter. The disadvantages of dielectrics are the fact they are so wavelength and angle of incidence dependent. This means if you are needing performance over a large range of wavelengths and angles you are most likely better served with a metal mirror.

  • Protected aluminium

Protected aluminium is the most common mirror coating material. It offers a reflection of approximately 86% through the visible while being a tough and resilient coating. The majority of optical mirror applications will be well served by using protected aluminium.

  • Enhanced aluminium

Enhanced aluminium is the process of putting a multilayer dielectric on top of aluminium. This can increase reflection performance up to the 94-95% while still being tough and resilient.

  • Protected Silver

If you really need the most efficient mirror protected silver might be the way to go. Silvers offers the highest reflection of metals in the visible at upwards of 95-96%. The major downside of Silver is that it doesn’t adhere well to glass so the coatings tend to not be as strong as other metals. This can make cleaning these mirrors difficult, it is also not advised to be using Silver if your application is outside and likely to experience harsh conditions.

  • Protected gold

Protected gold mirrors are best used in the infra red range typically achieving a 96% average reflection between wavelengths 0.8-20 micron. Gold due to the nature of it is expensive to put up.
