Acrylic filters are often used for larger displays and also where contrast enhancement is required ( due to the large range of tints available ). For these filters we use a high grade cast acrylic which can be obtained down to 0.5 mm thick.

The large range of tints available allows specific wavelengths to be transmitted. This can be used to contrast enhance, color correct or produce band pass filters. Infra-red filters are also manufactured to block visible light and transmit IR at around 90%.

All acrylic filters can be finished with a hard coat, for abrasion and solvent resistance, which can be applied as a gloss or matt surface.
