The Kowa TSN-884 is an incredibly solid and clear spotting scope. The pure Fluorite Crystal used in these models is the optimum optical material to reduce chromatic aberration, providing the ultimate viewing experience. The large 88mm lens makes it possible to observe at dusk and at sunrise. Made of magnesium, the Kowa Spotting Scope TSN-884 has an advanced moulding process that makes it feel like metal, but is lighter than its rivals. This makes the Kowa TSN-884 indispensable during observations. The robust magnesium body can withstand the toughest conditions, is waterproof and filled with dry nitrogen gas to prevent fogging of the lens.
Chromatic aberration occurs due to the diffusion of light and the different wavelengths of light that concentrate at different positions, which can result in a red or purple border around the subject. The optimal optical material to minimize chromatic aberration is Fluorite Crystal. For the convex lens of the TSN-883/884, a Fluorite Crystal with extremely low dispersion characteristics is used. Instead of an ordinary optical glass lens, the hollow lens in combination with the Fluorite Crystal lens is made of glass with special dispersive properties to further reduce chromatic aberration.This combination virtually eliminates chromatic aberration and redefines the standards for color brilliance.
Fluorite crystal is only used in the top models of Kowa.
