Kowa Genesis Prominar XD Binoculars
Kowa Genesis XD binoculars are high performance binoculars, and the first series to use the PROMINAR brand name, a designation meaning they use four XD lenses. The lenses are convex, and made of special glass that relays colors without aberration. Together, the four lenses create bright images with high contrast and true colors to a degree not acheived by normal achromatic lenses.
Also contributing to the contrast and image clarity is a phase-coated prism. It's a high refractive index prism, which allows for a wide field of view, sharpness from edge to edge, and little loss of light. Kowa's proprietary C3 coating increases the prism's reflective properties. The objective barrels are threaded, making it possible to attach filters in front of the lenses, and a locking mechanism on the diopter prevents accidental adjustments. Kowa Genesis XD binoculars are waterproof thanks to dry nitrogen filled barrels, and come with Kowa's Limited Lifetime Warranty.
