Engineers at Kowa have improved the unique optical coatings applied not only to the lenses but also to the prism in the new Kowa TSN-66 PROMINAR series of spotting scopes. The result is a telescope that offers even higher levels of light wavelength transmission than its predecessor and most important of all, across the entire color spectrum for nature's most natural color.

The new TSN-66 series incorporates a 66 mm pure fluorite glass objective lens, the true optical engine at the heart of all PROMINAR flagship optics. This unique lens redefines color brightness standards and eliminates chromatic aberration for one of the most detailed views of the natural world.

Fluorite glass offers the best viewing experience available today, eliminating virtually all chromatic aberration and providing images of outstanding resolution and contrast. Fluorite is considerably more difficult to manipulate than optical glass and requires very advanced processing technology. Kowa has taken special care, time and technique to produce the best visual experience with a pure fluorite glass lens. It is what makes Kowa unique.
