Heliopan Circular Polarizer Standard Type with Front Filter Threads
Construction: Heliopan Polarizing filters are made with a neutral color foil lamented between to parallel plane glass discs. The foil is constructed so the the light rays can only pass in one plane. The Polarizing filter is mounted in a calibrated rotating ring so the desired position and effect can easily be set. Heliopan filters have a lifetime warranty.
