— advantage of Nano Crystal Coat
Taken with a Nano Crystal Coat-applied lens
Taken with an ordinary lens
Nano Crystal Coat, employing multiple layers of extra-low refractive index coating that
features ultra-fine crystallized particles of nano size (one nanometer equals one millionth
of a millimeter), eliminates internal lens element reflections across the entire spectrum of
visible light (380 – 780 nm) far more effectively than conventional anti-reflection coatings.
Ghost caused by red light that has been thought difficult to reduce conventionally has been
remarkably reduced. Outstanding results are also found in reducing ghost and flare caused
by light entering the lens diagonally.
To investigate the effect, two lenses of
the same type — with/without Nano
Crystal Coat were used.
Notice the dramatically reduced flare
within the area.
