The Kowa Spotting Scope TSN-88S Prominar is the improved successor to the Kowa TSN-882 which has been a leading model in the field of spotting scopes since 2006. Kowa has provided the lenses and prism of the TSN-88S with new and improved coatings. With this, Kowa succeeded in obtaining an even higher light transmission. Than its predecessor and also provides the most natural colours across the entire colour spectrum.
In addition, the TSN-88S Prominar now benefits from 100% magnesium alloy, making it not only stronger but also lighter than its predecessor. The TSN-88S is easy to carry and has a fully waterproof and nitrogen-filled housing. An upgraded Kowa KR coating on the optics makes the scope incredibly reliable and robust.
Just like the TSN-882, the body is equipped with a large 88mm pure fluorite crystal lens which, in combination with a Kowa XD lens, delivers superior low-light performance. This special combination, plus the improved optical coatings, virtually eliminates chromatic aberration, even at high magnifications. Equipped with a dual focus mechanism, the TSN-88S allows fast and accurate focusing with just your index finger - in just a few smooth turns. The fine focus mechanism provides the final control for razor-sharp viewing.
Kowa TSN-88S with TE-11WZ II WA eyepiece
This kit comes with the Kowa TE-11WZ II wide-angle eyepiece. This eyepiece has a magnification of 25x-60x and features two XD lenses, so the images are displayed with excellent sharpness. The eyepiece is fully waterproof and equipped with a Twist-up eyepiece ring with three positions. This allows you to adjust the distance between your eye and the eyepiece. In this way, both spectacle wearers and users that do not wear glasses have a pleasant viewing experience.
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-88A/88S, 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.
Key features Kowa TSN-88S Prominar:
- Large 88mm fluorite crystal lens
- The fluorite used as an optical lens is an artificially grown monocrystal with "ultra-low dispersion", a property that ordinary optical glass does not have. It is an ideal lens material that almost completely eliminates chromatic aberration (colour blurring). The fluorite crystal produced by the advanced processing technology Kowa has built up over the years guarantees the ultimate viewing experience.
- Dual focus mechanism (Quick and fine focusing)
The fast focus, with a large and easy-to-turn knob, will focus in two revolutions from infinity to five meters. The fine focus, with smooth movements and great precision, is extremely useful at high magnifications and for digiscoping. - Fully Waterproof and Nitrogen-Proof
The body is completely sealed to protect it. The robust construction can withstand the toughest conditions. This provides confidence and a sense of security. - KR Coating
The objective lens benefits from enhanced protection by the upgraded KR coating. The KR coating actively repels dirt, moisture and dust from the surface. - Sun shade
A smoothly rotating sun shade helps eliminate glare and also reduces the exposure of the objective lens to the elements, such as moisture, grit and sand. - Eyepiece release button
To release the eyepiece smoothly, the release button has been redesigned. This makes it even easier to quickly change the eyepiece or adapter without compromising a secure connection to the body. - Strong, lightweight and portable
Thanks to a 100% magnesium alloy body, the TSN-88 Prominar series is one of the most compact and lightweight spotting scopes of its size. A fully waterproof and nitrogen-sealed housing plus Kowa KR coating on the optics makes the spotting scope reliably robust.
Another great advantage of magnesium alloy is that there is no turbulence in the body. The light rays pass straight through the body and the image is incredibly quiet. - Filter thread
There is a 95mm filter thread on the body of the TSN-88S, which can be used to add a protective or UV filter for enhanced protection.
The sun shade can still be used even with a filter. - Designed for digiscoping
100% compatible with the KOWA SYSTEM. Easily change eyepieces, accessories and use digiscoping adapters for DSLR cameras and smartphones. Create a truly flexible optical instrument for many applications.
