KOWA TSN-99S 99mm PROMINAR spotting scope + TE-11WZ II (straight-view)

Kowa 99mm Prominar Spotting Scope (Straight View)

Crystal clear in the truest sense of the word

At the heart of all Kowa PROMINAR flagship spotting scopes are the unique lenses made of pure fluorite crystal. For the TSN-99 PROMINAR, the largest lens ever produced was developed with 99 mm effective diameter. Even in low light, it offers outstanding optical performance with crystal clear detail and free of chromatic aberration.

Crystal clear - an expression you hear often in the optics world. A piece of pure fluorite crystal, crafted with the utmost care, is used in the form of a perfectly polished and fully coated lens to realize the definition of crystal clear vision. For the first time in a Kowa spotting scope, an ultra-low dispersion XD lens is used for the convex lens of the objective. Coupled with the concave lens made of pure fluorite crystal with its special dispersion properties, chromatic aberration is reduced even more dramatically. This combination means that color fringing is no longer perceptible, even at high magnifications. This technology defines a new standard of color brilliance and is the result of decades of development work by Kowa.

Dual-Focus

The dual-focus mechanism provides the best possible conditions for accurate focusing. The mechanism has been refined to allow perfect focus adjustment. Quick focus allows rapid adjustment to bring the subject into focus with just a few smooth turns, while fine focus allows pinpoint control even when wearing gloves and provides the ultimate in focusing accuracy. The responsive focusing system is geared to not only facilitate conventional observing, but also in specialized applications such as digiscoping, this technology brings key advantages for pinpoint focus adjustment.

Form & Function

Form and finish make a Kowa spotting scope iconic and distinctive. Starting with the classic green spotting scope body with its contours and black design elements, the body is elevated to a new level of elegance and lines. But looks are not everything, every shape element, no matter how small, has been optimized in the design phase to ensure not only good looks but also the best possible comfort and ease of use. Perfect ergonomics combined with superior optical properties create a spotting scope that will keep you well equipped for years of use.

Built to withstand all weather conditions

Beneath the TSN-99 PROMINAR's beautifully designed surface is an extremely durable housing made of a high-quality magnesium alloy. This lightweight material is manufactured using a special molding process called "tixotropic molding." This creates a housing that brings all the strength benefits of metal, but is still very lightweight. The TSN-99 PROMINAR is one of the lightest, most compact and therefore most portable spotting scopes in its class.

Ultimate versatility

The TSN-99 PROMINAR's accessory thread and bayonet mount offer 100% compatibility with our KOWA SYSTEM line of accessories. You have access to interchangeable eyepieces and many other accessories for extensive and flexible applications.

Kowa TE-11WZ II 30-70X Wide Angle Zoom Eyepiece

The optical design of Kowa's TE-11WZ II is of a particularly high standard. It is the first Kowa eyepiece to incorporate 2 XD lenses, which limits chromatic aberration in the best possible way. Even at 70x magnification, the sharpness is still excellent. The exit pupil distance of 17mm remains identical over the entire magnification range.
