Nikon (N) Nano Crystal Coat

Nano Crystal Coat is an antireflective coating that originated in the development of NSRseries (Nikon Step and Repeat) semiconductor manufacturing devices. It virtually eliminates internal lens element
reflections across a wide range of wavelengths, and is particularly effective in reducing ghost and flare peculiar to ultra-wideangle lenses. Nano Crystal Coat employs multiple layers of Nikon's outstanding extra-low refractive index coating, which features ultrafine crystallized particles of nano size (one nanometer
equals one millionth of a mm). Nikon now proudly marks a world first by applying this coating technology to a wide range of lenses for use in consumer optical products.
