CTC81EF 85x85 Resin

The Silvestri resin filters are made from durable, lightweight, optical resin 1.5 mm thick. They have excellent contrast and are completely transparent to the visible light spectrum. The resin used has the highest scratch resistance of any non-glass optical material and its resistant to most solvents, chemicals, aging and material fatigue. Because of the ruggedness, light weight and portability, resin filters are a great choice for photographers and HDSLR filmmakers. Resin filters are dyed using our exclusive Absorbing Cell Technology process.
