The Genesis Series incorporates a total of 4 XD lenses (2 sets of 2 lenses) to significantly reduce chromatic aberration and provide a high contrast in the field of view. The wide angle eyepiece design increases the field of view in the 8x by 28% (420ft @ 1000yd) and 10x by 14% (360ft @ 1000yd) compared to the BD32 Series.

Kowa XD Lenses
Kowa's XD Lenses (eXtra-low Dispersion glass with similar characteristics to fluorite crystal) combines with a special dispersion concave lens to reduce a very high percentage of chromatic aberration for the ultimate viewing experience.

Schmidt-Pechan Roof Prism Lens and C3 Coating
Kowa's roof prism binoculars use a Schmidt-Pechan prism. With the highly reflective C3 coating application, this increases reflectivity by 99% or higher reflectance rate across the entire visible spectrum (400-700nm). This not only provides bright and sharp images, but also accurate color reproduction.

Kowa's KR Coating
Kowa's KR coating protects the lenses from dirt and other foreign residues that may affix to the lenses during normal use. Fingerprints or oil can easily be removed with the proper lens cleaning techniques.

Phase-Coated Roof Prism
The Schmidt prism roof surface is phase corrected to ensure sharp images for the most outstanding image contrast.

All-Surface Multi-Coating
The all-surface multi-coated optical system provides a precise color definition for a brighter and sharper image.

Waterproof and Fogproof
The housing is waterproof to JIS Protection Class 7 and filled with dry nitrogen gas to prevent internal fogging to ensure image clarity.

Twist-Up Eyecups
Twist-up multi-step eyecups allow customization for easy viewing even when wearing eyeglasses
