XD Lenses
Kowa’s branded XD Lenses (eXtra-low Dispersion glass which has characteristics close to fluorite crystal), when combined with a concave lens possessing special dispersion properties, reduces a very high percentage of chromatic aberration (color blur).

C3 Coating
Kowa’s roof prism binoculars use a Schmidt-Pechan prism. One surface of the Pechan prism does not provide total reflection, so a highly reflective C3 coating has been applied. This allows for higher reflectivity than with silver or optically enhanced aluminum which offers a 99% or higher reflectance across the entire visible spectrum (400-700nm). This not only provides bright and sharp images but also accurate color reproduction.

Magnesium alloy body 
Advanced thixomolding technology provides the benefits of a high strength metal body but in a lightweight magnesium alloy structure.

The durability and reliability of these binoculars can withstand the most severe conditions which provide users the greatest degree of confidence.

Phase Coating
Phase coated roof prism ‒ The Schmidt prism roof surface is phase corrected to ensure sharp images and outstanding contrast.

All-surface Multicoating
Multi-coated Optical System provides precise color definition for a brighter and sharper image.

Waterproof structure filled with WP dry nitrogen gas
The housing is waterproof and filled with nitrogen gas which prevents internal fogging.
**Not intended for underwater use.

Twist-up Eyecup
Twist-up multi-step eyecups allow easy viewing even when wearing eyeglasses.
