Kowa TSN-99A Prominar

What our customers say:

Kowa optics are particularly bright and sharp. This TSN 99 scope is also good for zooming in up to x70 but also performs brilliantly with the new x40 eyepiece. Ideal for digiscoping. It is slightly heavier than the TSN 883 though but not too much. The TSN 99 is as near the perfect birding scope you will get and oozes quality."

BRIGHT, WIDE CRYSTAL CLEAR

A large 99mm pure fluorite crystal objective lens paired with a Kowa XD concave lens produces superior lowlight performance and exquisite detail. This special combination combined with improved optical coatings virtually eliminates chromatic aberration even at high magnification.

THE ULTIMATE VIEWING EXPERIENCE

Fluorite crystal delivers the best viewing experience available today, eliminating virtually all chromatic aberration and delivering images of outstanding resolution and contrast. Fluorite is considerably more difficult to handle than optical glass, it requires highly advanced processing technology. Kowa put forth extra care, time and technique to produce the ultimate viewing experience with a pure fluorite crystal lens. It’s what makes Kowa unique.

The objective lens has further protection from the elements with Kowa’s unique KR coating which actively repels dirt, moisture and dust from building on the surface.
