More about the series TSN 660...
KOWA has re-engineered its success story!
The most conspicuous innovation is its new rubber casing. Like the models from the 880 and 770 series, this is now available in “KOWA green”. Furthermore, Kowa has treated all external lenses with a nanocoating which repels water and allows dirt to be more easily removed.
- The lens has more than 120% the light gathering capability of a 60mm objective lens.
- All lenses, prisms, and dustproof glass are fully multicoated, ensuring sharp images and a clear visual range.
- The housing is 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.
