The colour effects within Wratten 2 Colour filters are achieved using organic dyes in a gelatine material which is not possible in colour glass. Although wratten bandpass filters are less robust than polyester filters, their spectral data is more accurately controlled and documented. The filters listed here are band-pass type Wratten 2 colour filters. Wratten 2 filters were originally designed for use in photography but are also used in imaging applications from industrial manufacture to medical.
