Wratten colour filters are manufactured by using organic dyes in a gelatine material to achieve the desired colour effects, which is not possible in colour glass, especially shortpass types. Thinner substrates can also be achieved and at 0.1mm thick may be useful where space is limited. The well-known `Wratten` gelatine filters are the wider range and are more accurately controlled and documented. The Polyester Filters are much more robust and less expensive optics.
