Our core business is the development and production of optical filter elements used in 3D displays. The filters themselves consist of a thin carrier material (0.1mm film or 0.1 – 3mm thick glass) to which one or more optically effective layers are applied. The parameters of the optically effective layer(s) and the layer structure depend, among other things, on the underlying LCD panel and the desired properties of the 3D display (number of views / viewing distance / image separation ratio / …).
