Type Dichroic Colour Correction CTB Filter

Knight Optical’s range of dichroic colour correction filters offer pure, true to life colour temperature adjustment for entertainment and photography.

Colour correction filters are typically used in mixed lighting applications where an object illuminated by more than one light source would show an inconsistent mix of shades. By applying colour correction the illumination can be controlled and the object or scene properly lit. Knight Optical’s colour correction filters are available in both tungsten and daylight conversion types in a variety of strengths to suit your application.

Our dichroic colour correction filters are available in a range of wavelengths and are supplied in standard 12.5mm and 25mm diameter or 50mm square types. We are happy to cut and edge filters for non standard sizes to suit your application.
