ALL ABOUT BINOCULARS

There are few outdoor activities which cannot be made more enjoyable by the use of binoculars. At races, on board ship, for hunting, bird watching, at the cottage, or for any outdoor use they will add interest and enjoyment. The optical construction of binoculars is similar to that of field glasses, except that prisms have been added which reflect the path of the light. Thus the effective distance between the objective lens and the eyepiece has actually been lengthened, and magnification of anywhere from six to twenty powers ! can be obtained without making the glasses bulky. All our prismatic binoculars are equipped with achromatic lenses.

THE POWER OF BINOCULARS is the number of times the object is magnified; glasses with a power of 8x magnify the object 8 times. This means, for example, that an object 4 miles away appears to be only half a mile away when using 8x power binoculars. The magnification power as well as the diameter of the objectives is usually engraved on binoculars. Thus the marking “8×30” “7×50” or “20×65” means magnification 8x 7x or 20x and objective lens diameter 30mm 50mm 65mm and so on.

FIELD OF VIEW is the extent of the field seen through the glasses. It is expressed either in angular measure or in feet at a distance of 1,000 feet. That is to say that a glass with a field of view of 150 will show you 150 feet of landscape at 1,000 feet – proportionately greater fields at longer ranges and less at shorter ranges.

Unfortunately the greater the magnification the less the field of view. This is an optical fact. It follows, therefore, that if you choose glasses with large magnification you must be prepared tb accept a smaller field of view than you would obtain with less powerful glasses.

COATING. It is a well known optical, phenomenon that under normal conditions, a loss of over 5% occurs when light passes through an air-to-glass surface. An optical instrument such as binoculars containing many air-to-glass surfaces must, therefore, fail to transmit a considerable portion of the light it receives. “Coating” of the lens surfaces reduces this loss. “Coating”, therefore, has two obvious advantages:

(1) The image or field of view is considerably brighter due to the increased transmission of light.

(2) Contrast and definition are improved because of the almost complete elimination of stray light reflected to and fro between the various lens surfaces.

These Chinon binoculars have deep ultra violet coating on the lenses.

FOCUSING.

The distance between people’s eyes varies. To accommodate such differences, the two barrels of the binoculars are hinged to each other so that the distance between the eyepieces can be adjusted until the two separate images, from each half of the binoculars, merge into a single image. At this position the reading on the scale should be noted, so that it may be reset with ease on future occasions.

There are two types of binoculars:

(1) Central focusing mechanism = C.F.

(2) Individual focusing mechanism =.I.F.

The CENTRAL FOCUSING adjustment has a wheel mounted between the tubes of the binoculars, controlling the movement of the eye lenses for focusing purposes. One of the eyepieces, the right one, is adjustable for compensating any variations in strength of the eyes.

The INDIVIDUAL FOCUSING MECHANISM : No centre wheel is supplied. Each ocular lens has to be focused separately and independently.
For this purpose both eyepieces are marked in diopter scales for convenience in setting.

Chinon Industries Inc. was established by Chino Hiroshi in September 1948 and was originally known as Sanshin Seisakusho. Its name changed in 1962 to Sanshin Optics Industrial Co. Ltd, finally becoming Chinon Industries Inc in 1973.

It is now owned by Kodak Japan Limited, the Japanese daughter company of Eastman Kodak Co. It sells digital cameras to Kodak and provides assistance to Kodak Electronic Products (Shanghai), the manufacturer of its cameras. The takeover by Kodak took place in January and February 2004.
