Acrylic longpass filter sets
What are you looking for in Stock?
Acrylic colour filters are similar to colour glass filters, achieving their colouration by the use of dyes during the manufacturing process. Acrylic filters are cheaper than glass filters, easier to cut to special sizes and shapes but not quite as robust as glass. A rather wider range of spectral characteristics is available than with glass.
Two particularly useful types of acrylic colour filters are those which block the visible but pass near IR and the ones that pass the visible but block UV light. Our filter sets include filters designed for specific wavelengths ranges, or filters spanning over the visible to near infra-red spectral range.
