I am looking for wavelength profiles for various cokin filters. Would anyone have a reference?

If they use the Wratten numbers, those spectrals are standards and available. If they are Cokin 'special', the you'll have to go to Cokin.

Same if they are German “international” numbers, same curves as Wratten. If you have any marked in decamired they are also universal.
