Carlstadt, NJ—Argraph, a supplier of photographic/imaging products, offers Marumi Digital High Grade (DHG) filters for digital cameras. Marumi DHG filters feature a digital super coating to provide the “ultimate performance and protection” for lenses.
Marumi Optical Company of Japan designed the DHG range of lens filters to eliminate the flare and ghosting prevalent when the CCD or CMOS chips in digital cameras convert light into electrical signals. The filters incorporate Marumi’s ultra-low reflection coating to increase light transmission, and to minimize internal reflection Marumi manufactured the DHG filters’ outer rim with an ultrathin matte black frame.
