Ofil's solar blind filters
Solar blind filters are the core technology of Ofil.
Dye Doped polymer technology (DDP) is used to produce solar blind UV bandpass filters with exceptionally high levels of rejection outside the transmission band. Ongoing R&D continues to produce new materials to extend the filtering capabilities of the technology.

 UV Transmission chart
The white line shows solar radiation reaching the earth surface.
The blue line shows filter transmission

Versions of this filter with higher peak transmission can be customized for use with various phtocatodes.
