A tradition of viewing excellence

Nikon's uncompromising commitment to quality has been in

evidence since its founding in 1917 when the company first began

making fine binoculars for discerning users.

Binoculars — the foundation of Nikon's business

The following year, Nikon exported over 15,000 high-quality prism binoculars to

England, France, the U.S.A. and the U.S.S.R. In 1922, Nikon collaborated with

German engineers to produce historic compact prism binoculars such as the

Mikron 4x and 6x, and later the Orion 6x24, 8x26 and Nova series in 1923.

Nikon — a leader in optics

Three years after the end of World War II, Nikon introduced a new Mikron series,

including a CF version of the Mikron 6x15. An elegant chrome finish

complemented the high-tech design.

Nikon creates a "new look" in binocular design

In 1964, Nikon developed the first fashion binoculars — compact models that combined

improved grip and operational comfort with superb optical performance.

1978 marked the introduction of the futuristic Compact Roof (Dach) Series 6x, 7x,

8x20DCF — sharp, compact, lightweight roof (Dach)-prism binoculars. They were

immortalised in 1980 when they were included in the permanent collection at the Museum of

Modern Art in New York.

Then, in 1982 Nikon developed the 8x23CF and 10x25CF binoculars in collaboration with

well-known industrial designer, Giorgetto Giugiaro.

A fusion of technology and tradition

Nikon binoculars' superb handling, sturdy construction and stylish design are the result of

state-of-the-art computer graphics renderings based on analysis of input specifications.

Nikon applied the highest optical technologies in developing the 8x42HG DCF/10x42HG DCF

binoculars, introduced in 1997. With the debut in 2002 of the 8x32HG DCF/10x32HG DCF

and 8x20HG DCF/10x25HG DCF HG series binoculars, Nikon made its lineup of high-grade

binoculars even more complete.

Superior optics and design innovations ensure better views.

Nikon HG series binoculars use the best optical technologies

For bright, high-contrast images

•Nikon's original multilayer coating

Minimises flare and ghosts, for very high transmission across a wide range of

wavelengths. The result: excellent contrast and colour reproduction.

•Phase correction coating

Corrects phase shifts caused when light reflects off the roof (Dach) prism. Provides

a high-contrast image by eliminating the reduction of resolution.

•High-reflection silver coating

Much greater reflectivity and much less light loss from the prism, compared with

ordinary aluminium coating, for brighter images.

For sharp, undistorted images

•Field flattener lens

Employed for eyepiece lens. Provides images that are sharp and clear all the way to

the lens periphery.

•Distortion correction

Nikon's superb optical design provides high-level distortion correction enabling

sharp, undistorted images even at the viewing area periphery.

Easy to use

•High-eyepoint design

Sophisticated design technology achieves a combination of high eyepoint and small

size.

The meaning of numbers found on binoculars

All Nikon binoculars are designated with a numerical formula, such as

"10x25 5.4°".

The value "10x" indicates the magnification of the binoculars. If a person uses

10x binoculars to observe a wild bird from a distance of 100 metres, for

example, it will appear (to the observer) as if he or she were viewing the bird

from a distance of 10 metres (100 divided by 10 equals 10) with the naked eye.

The next number, "25", tells you that the effective diameter of the objective

lens is 25mm. The greater the diameter of the objective lens, the brighter your

image will be with the same illumination. If the objective lens is too large,

however, the binoculars will be heavy and may cause trembling of the hands.

Finally, the number "5.4°" represents the actual field of view of the binoculars.

This is the angle of the visible field, as measured from the centre of the

objective lenses. The bigger the value, the easier it is to locate an object.

Understanding the meaning of these numbers should provide you with greater

freedom in selecting and using binoculars.

Check the letters in the name of any Nikon binoculars —

they convey helpful information about each model.

Light transmission rates

Generally speaking, the higher the light

transmission rate of a lens, the brighter and

clearer your image will be, with less blur

and ghosts.

Each of Nikon's high-grade binocular

models features a high light transmission

rate thanks to our multilayer-coated lenses

and prisms.
