The angled TSN-88A 88mm PROMINAR Pure Fluorite Spotting Scope from Kowa is a world-class spotter that redefines the standards of color brilliance, sharpness, and brightness. The TSN-88A uses an element of pure fluorite crystal (PFC) glass in its construction, which greatly minimizes chromatic aberration. This ensures maximum efficiency in its light gathering, producing a clear visual range and sharp imagery that traditional glass lenses cannot attain at their highest magnifications and with the strongest of subject/background contrast changes. The housing is made of a magnesium alloy that defines maximum durability and lightweight construction, resulting is a compact, ergonomic, and functional design for extreme nature and outdoor enthusiasts. An eyepiece is not included and sold separately.

Kowa TSN-88A 88mm Spotting Scope Overview
Proper functionality of the retractable sunshade is guaranteed exclusively with Kowa brand filters.
Fluorite crystal lenses makes for the ideal lens material with ultra low dispersion properties not possessed by an ordinary optical glass. This outstanding specification adds the featured benefit of a near-completely reduced chromatic aberration, or color blur, to provide users with the ultimate viewing experience.
A dual tripod mounting screw allows the scope to be safely secured to both 1/4 and 3/8" mount.
Kowa's standard eyepiece bayonet mount includes a locking mechanism to prevent the eyepiece from getting lost or falling out unexpectedly. An eyepiece is sold separately.
The magnesium alloy body and barrel is constructed by a sophisticated process called thixotropic molding to give the strength and feel from a traditional metal body but with much lighter weight. The rugged structure can tolerate the severest conditions and deliver the highest level of confidence and security.
Kowa's focus system has progressed to a dual focus system with smooth movement at high magnification for pinpoint accuracy in image display. The quick focus can easily shift from infinity to 16 feet in two revolutions with the large and maneuverable knob. The fine focus moves fluidly to create pinpoint accuracy and is extremely useful at high magnifications and with digiscoping systems.
The housing is waterproof to JIS Protection Class 7 and filled with dry nitrogen gas to prevent internal fogging to ensure images clarity.

Kowa TSN-88A 88mm Spotting Scope Reviews
Arguably the finest Spotting Scope for its Objective Size.
By David
Rated 5 out of 5
Date: 2026-09-16
The Kowa TSN-88A Prominar Spotting Scope with its pure Fluorite glass is without question one of the finest spotting scopes in its class. Most birders and hunters will acknowledge it's at least in the top three and/or tied for the top spot. Optically, there are only two others in its class: the Zeiss Harpia and the Swarovski ATX 85 both of which are significantly more expensive and many people still feel the Kowa is better. So, for the money, you cannot go wrong with the Kowa. Try it out in the store, borrow it from your friends, do whatever you need to do to try it - you will love it.
