Polyester filters have the dye held in a thin sheet of polyester, less than 0.1 mm thick.  These shortpass polyester filters are reasonably robust and inexpensive. They are available in sheets at 75mm square and can be cut to custom dimensions. At 0.1mm thick these polyester filters are flexible and the range offered covers the visible spectrum.

Polyester Colour Filters have a wide range of characteristics available and the sheets can easily be cut in the laboratory. Whilst Polyester filters are cheap and simple to use, the characteristics are not as well controlled as other absorption types and they can be susceptible to bleaching if large amounts of UV is present.

Our filter sets include filters designed for specific wavelengths ranges, or filters spanning over the visible to near infra-red spectral range. 

These polyester shortpass filter sets are more cost effective than purchasing as individual filter wavelengths and supplied in a high quality wooden box, which is very useful for laboratory and custom design applications for ease of use and safe keeping.
