Kowa 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 offi cial 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

Lens

FC Fluorite Crystal Lenses

These fluorite crystal lenses, manufactured with Kowa's advanced processing technology that was acquired over many years, provide users with the ultimate viewing experience.

Fluorite Crystal Lenses

XD XD Lenses

Kowa’s 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.

XD Lenses

Features

DF Dual Focus Mechanism (Quick and Fine Focusing)

The well established Kowa focus system has progressed to a dual focus system. The quick focus, with a large and easy to turn knob, will focus from infinity to 5m in two revolutions. The fine focus, with smooth movement and pinpoint accuracy, is extremely useful at high magnifications and for digiscoping systems.

Dual Focus Mechanism

EL Eyepiece Locking Mechanism

Kowa's standard eyepiece bayonet mount has been passed down to these spotting scopes with a attractive feature. An eyepiece locking mechanism has been added to the mount to prevent the eyepiece from getting lost or falling out unexpectedly.

Eyepiece Locking Mechanism

MB Magnesium Alloy Body

The magnesium alloy body made by a sophisticated molding process called thixotropic molding has the feel and strength of a traditional metal body with decreased weight when compared to other large diameter scopes. The rugged structure can tolerate the severest conditions and provides confidence and a sense of security for the user.

Magnesium Alloy Body

TS Tripod Mounting Screw

The addition of a insert to the tripod mount of the scope allows the scope to be secured to both 1/4 and 3/8 inch mount tripods.

Multi-Coated Processing Applied to All Lens Surfaces

All lenses, prisms, and dustproof glass are fully multicoated, ensuring sharp images and a clear visual range.

WP

Completely Waterproof Structure filled with Dry Nitrogen Gas

The housing is waterproof to JIS* Protection Class 7** and filled with dry nitrogen gas to prevent the lenses from fogging.
** Not intended for underwater use.

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.

Telephoto Scope

PROMINAR Super-Telephoto Lens and Scope

Telephoto Lens/Scope Series

The pinnacle of optical performance.

PROMINAR super-telephoto lenses incorporate fluorite crystal lenses to realize a high resolution

In order to limit chromatic aberration (color blur) to the utmost, which tends to easily occur in lenses with long focal lengths, one fluorite crystal lens and two XD (eXtra low Dispersion) lenses having particularly low dispersion capabilities are utilized. By bringing together advanced optical technology fostered through the development of spotting scopes, and incorporating fluorite crystal lenses with outstanding optical characteristics, high contrast and extremely sharp images can also be realized a s a camera lens.
Further, due to the high-level aberration correction and the utilization of a rounded diaphragm, an attractive effect can be obtained in out-offocus areas as the pinnacle of imaging expression for a camera lens.

Dual-focus system that realizes ease of use in manual focusing

To enable the focus to be precisely adjusted by manual focusing, Kowa spotting scopes also utilize a highly reputed dual-focus system. In addition to using a high-contrast optical system that enables the focusing peak to be easily determined, a dual-focus system consisting of a quick focus that swiftly matches the focus and a fine focus for delicate focus adjustment is used. This enables precise adjustment to be carried out, even under the severe conditions encountered in super-telephotography.
