Fabricantes japoneses de prismáticos.

[Valakirka]

Hola a todos los binófilos, la relación siguiente la encontré por casualidad buscando por la red una determinada marca de unos antiguos prismáticos japoneses. No sé si es totalmente exhaustiva, pero amplia si. Y, en mi opinión, no está de más tener una relación así a efectos de una consulta para disipar dudas. Espero que resulte útil.

Japanese Manufacturer's Codes for Optical Products.

Most Japanese binoculars from the 1960s and several decades later carry one
or two tiny marks on the body, about 2 mm in height, frequently adjacent to
the hinge axis on the rear, between the objectives. 'JB' and two or three
digits identifies the manufacturer of the finished binocular, and 'JE'
identifies the maker of the body. The J symbol has a small horizontal line
extending from the middle of the J, and is explained in a pamphlet from the
Japan Binoculars Export Promotion Association, _'63 Binoculars From Japan_.
"Combining the letters L and J (standing for Light Machinery of
Japan)......on the shoulder hinges or support strut of all approved
binoculars manufactured in Japan since November 1959." The JBEPA had their
US office in the Japan Trade Center, 393 Fifth Ave, NY.
This list was obtained by Bill Beacom, who arranged for its translation, and
converted to electronic form by Fred Schwartzman. A second, later, list
added further companies; the earlier list used 'Kogaku' and the later list
used 'Optical'. No dates are available for either list.
We are looking for the manufacturers represented by the missing numbers 65,
66, and 209.

Checkup On Quality - JAPANESE BINOCULAR INSPECTION INSTITUTE

Binoculars from Japan are rigidly inspected to make sure that every
component is of top quality and that all mechanisms are in perfect working
order. All optical products that have passed these rigorous standards are
tagged “PASSED” by the Government’s Japan Telescopes Inspection Institute.

The JL mark: Only those binocular and optical manufacturers meeting Japan’s
Government standards of inspection and quality may use the authorized JL
symbol. This symbol accompanied by the letter “E” or “B” and the number of
the respective manufacturer is engraved on the objective-end hinge or on the
cover plate. The letter “E” designating the metalwork manufacturer is
engraved on the right and the letter “B” designating the manufacturer of the
finished product is on the left.

“PASSED” labels. This oval silver paper label marked “JTII” certifies that
binoculars have complied with the export standards of the Japan Telescopes
Inspection Institute. It is usually found on the axle of the binoculars.

The quality of the JB marked products are rechecked by the Institute for
items that are exported. This rigorous Government system insures that only
top quality binoculars are exported from Japan. Know your dealer. Your final
check on a quality pair of binoculars is your faith and reliance in your
dealer. A reputable dealer will stand behind his optical products.
