Kowa Genesis XD33 10×33 DCF Binocular

Seeking a world of binoculars without chromatic aberration. Flagship model incorporating XD lenses.

The Genesis Series incorporates Kowa’s “PROMINAR” lenses. To attain the highest pinnacle of binocular performance, a total of 4 XD lenses (2 sets of 2 lenses) are utilized in the objective end of the binoculars.

This significantly reduces chromatic aberration and provides high contrast in the field of view.

C3 Multi-coatings provide precise color definition and deliver optimal images. The new wide angle eyepiece design of the Genesis/XD33 Series has increased the field of view of the 8x by 28% (420 feet at 1,000 yards) and the 10x by 14% (360 feet at 1,000 yards) compared to the 32mm Kowa BD binocular series.

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.

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.

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