Optical Coatings

SOVIS OPTIQUE coatings can fulfil the following functions :  - Dichroic filters  - Anti-reflective coating  - Infra-red (Heat) filter  - UV filter  - Cold mirrors... Those coatings can be used in various lighting, optical or decorative applications, where there is a need to improve or to select part of the light produced by the source.

Dichroic Filters

Dichroic filters are designed to select one colour from a lamp while keeping a maximum light intensity.

Infra-red Filters

Infra red filters or heat filters are used with modern and powerful sources using halogen or Xenon. They protect lit equipment and downstream optics within affecting visible light intensity. Those filters usually improve visible light transmission as they have also anti-reflective properties.

Anti Reflective Coating

SOVIS provides simple or multi-layer treatments according to the level of transmission required. It is possible to control the residual reflected colour.

Others

Glass coating can achieve other interesting functions such as cold mirrors, UV mirrors or filters, light temperature corrective filters, self cleaning films...
