Optical Mirrors
Kingsview Optical specialises in manufacturing high precision optical mirrors for various industries, such as defence, science, and research and development. We have the capability to produce spherical plano and cylindrical mirrors in customised shapes and sizes. Our mirrors can be coated with front or rear surface aluminium, gold, silver, or custom dielectric coatings to meet your specific wavelength requirements.
In addition to mirrors, we offer a complete range of precision optical components, including spherical lenses, optical prisms, and precision windows. Our team also provides a custom lens design service, allowing you to share your optical requirements with us and receive a tailor-made solution.

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
Silver offers the highest reflection of all metals in the visible spectrum, reaching levels upwards of 95-96%. However, there are some drawbacks to consider. Silver doesn’t adhere well to glass, which means the coatings may not be as durable as those made with other metals. This can make cleaning these mirrors quite challenging. Additionally, if your mirror will be used outdoors and exposed to harsh conditions, using silver may not be the best choice.
- 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.
