Mirrors
Metal mirrors are used in applications where absorption loss can be tolerated or where a high degree of angular tolerance is required.

Metal based mirrors suffer from considerable absorption loss, although for many simple systems this is not a problem. For systems using high powers or multiple reflections, however, the absorption loss of metal layers cannot be tolerated. Dielectric quarter-wave stacks provide the solution. We can offer quarter-wave stacks centred on customer specified wavelengths.

Beamsplitters
Siltint offers tailor made beamsplitters to customer specifications. Both polarising and non-polarising components are available as used in optical systems for colour and polarisation separation.

Filters
Dichroic edge filters have spectral characteristics showing a sharp change between a high transmission region and a high reflectance region. They are generally separated into short wave pass or long wave pass filters and find application in blocking unwanted wavelengths.

Special coatings
You can specify any design or material combination and we will endeavour to deposit it. This includes materials such as, for example, Hafnium Oxide, Zirconium Oxide, Copper, and Indium Tin Oxide.
