KOWA BINOCULARS

a Brand cherished by outdoor enthusiasts around the world

- a testament to quality.

The Electronics & Optics business of Kowa began the production of spotting scopes in 1952. Originally, they were developed as scopes for examining targets in shooting matches and saw official use in the 1964 Olympics Games held in Tokyo. Once discovered by birdwatchers, they gained unexpected popularity which gradually spread throughout the world of nature observation. Kowa Sporting Optics are highly appreciated as it is widely known that their quality and reliability are the result of more than half a century of experience and development. Kowa's larger aperture models enjoy a large market share in Europe and North America.

The Prominar line which includes models utilizing pure fluorite crystal to achieve optical characteristics unattainable with glass, is the gold standard of serious users.

Based on our experience that optics have to travel and endure all types of adverse environmental conditions, Kowa Sporting Optics are designed to be rugged yet lightweight, without compromising optical performance. The shapes of our products and their protective covers are ergonomically designed to optimize ease of use, and Eco-Glass is utilized in all lenses. Kowa offers a wide variety of products that provide quality optical performance for the outdoor enthusiast.

Whether you are a beginner or an experienced professional, Kowa has the right spotting scope or binocular that will exceed your expectations.

Eco-Glass is an environmentally friendly glass that not contain lead or other harmful substances.

OPTICAL TECHNOLOGY

FC Fluorite Crystal Lenses

Fluorite crystal is an ideal lens material with “ultra-low dispersion” properties not possessed by ordinary optical glass. This outstanding feature almost completely reduces the chromatic aberration (color blur) that occurs in the design of long focal length lenses.
These fluorite crystal lenses, manufactured with Kowaʼs advanced processing technology that was acquired over many years, provide users with the ultimate viewing experience.

Applicable Models: HIGH LANDER

Fluorite Crystal Lenses

XD 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). Their performance nearly matches Kowa’s flagship models which utilize fluorite crystal lenses.

Applicable Models: GENESIS Series, BD-XD Series

C3 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.

Applicable Models: GENESIS Series, BD-XD PROMINAR Series, BD Series

MB Magnesium Alloy Body

A magnesium alloy body is formed using advanced thixomolding technology.
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.

Applicable Models: GENESIS 44, BD-XD PROMINAR Series

KR KR Coating

Kowa's KR coating protects the lenses from dirt and other foreign residue that may affix to the lenses during normal use. Even in cases where the lens is accidentally touched, fingerprints or oil can easily be removed through proper lens cleaning methods.

Applicable Models: GENESIS 44, BD-XD PROMINAR Series, SV Series, YF Series

Other Functions:

PC Phase Coating

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

Applicable models: GENESIS Series, BD Series, SV Series

MC All-Surface Multicoating
