F2


Contamac’s basic F2 GP range uses fluorosilicone acrylate to improve wettability and deposit resistance. Its excellent machining properties make it ideal for thin lens designs, routine spherical fits, some sophisticated designs, as well as fitting set lenses. With a range of Dk values, all sharing the same chemistry, the F2 range promises both fitting-comfort and predictability.
