Spotting scope TSN-883 + TE-11WZ+C-881 Set

Series TSN-880

The pure fluorite crystal used in these models is the optimum optical material for reducing chromatic aberration, providing the ultimate viewing experience. (TSN-883/884 only.)
The extraordinary light gathering capability supports observation during dusk and during dawn.
All spotting scopes are waterproof to JIS protection class 7 and filled with dry nitrogen gas to prevent the lens from fogging.
JIS 7 = Japanese Industrial Standard / class 7 = Protected against the effects of temporary immersion in water.

Kowa uses pure FLUORITE CRYSTALS in the TSN 883 and 884 models – this is a unique selling point for Kowa:
Competitors use fluoride glass, i.e. ‘only’ a fluorite additive, whilst we grind a pure fluorite crystal and use it as a lens. This serves primarily to prevent colour fringing.

Further technical features:

• All lenses are made from ECO glass
• The internal focusing system reduces image shake.
• Dual-focusing system with 2 focusing wheels: the larger focusing wheel is for quick focusing – the entire focus range from 5 m to infinity is covered by 2 turns – whilst the smaller focusing wheel is for fine-tuning, making it easier to achieve precise focus, particularly at higher magnifications.
• The eyepieces are protected from falling out or getting lost by a locking system.
• Both the spotting scopes and the eyepieces are waterproof and filled with dry nitrogen to prevent misting.

The TE-11WZ wide-angle zoom eyepiece is included in the scope of delivery. These eyepieces are also waterproof and feature eyecups suitable for spectacle wearers, offering a magnification range of 25-60x.

The exit pupil distance, which remains constant at 17 mm across the entire magnification range, enables fatigue-free observation over long periods of time, is also very comfortable for eyeglass wearers and, at the same time, provides excellent conditions for digiscoping.
