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 its TSN 883 and 884 models – this is a unique feature of KOWA:
Our competitors use fluoride glass, i.e. "only" a fluorite additive, while we grind pure fluorite crystal and use it as a lens. This mainly serves to prevent colour fringing.
Further technical features:
- All lenses are made from environmentally friendly ECO glass
- The internal focusing system reduces image movement.
- Dual focusing system with 2 focusing wheels: the larger focusing wheel for quick focusing: the entire focus range from 5 m to infinity is covered with 2 turns, the smaller focusing wheel for fine focusing, especially at higher magnifications, makes it easier to focus precisely.
- The eyepieces are protected against falling out or loss by a locking system.
- Both the spotting scopes and the eyepieces are waterproof and filled with dry nitrogen to prevent fogging.
Attention: Eyepieces not included in shipment.
