Binoculars Carl Zeiss Jena Telex 6x (2)
In 1907, Carl Zeiss drastically changed the construction and design of his binoculars, replaced by the “civilian” Feldstecher 6 Fach models came Telex, Feldstecher 8 Fach - Telact, Jagdglas - Silvamar and Telefort instead of Feldstecher 12 Fach. Detailed specifications of the new devices are published in the Carl Zeiss T.74 catalog in August 1907. However, there are facts indicating that the sale of new models began a little earlier than this date.
In the new devices, the optical characteristics are significantly improved (the field of view, the diameter of the lenses are increased, optical aberrations are reduced), and the design of the devices is changed: the central hinge and the “ears” for the neck strap are not attached to the binoculars with screws, but they are one with it, an eccentric appears the lens alignment system and the design of its frame changes, prismatic covers cover the binoculars housing and, to improve tightness, are lubricated at the joints with a special compound. In addition, the prisms inside the binoculars are no longer pressed by prismatic covers, but are fixed with special flat springs, which greatly increases the reliability of the device. Serial numbers now have end-to-end numbering, regardless of model, and are placed on prismatic covers (on the side surfaces, or on the upper right cover). In fact, in this form binoculars have reached our time.
Telex is the smallest model with a new design, 6x magnification and 21mm lens in the very first version. This is a civilian model, however, there are instances with military features - mesh, large clamping screw, military numbering, etc. Its military counterpart is the D.F.6 model.
The “civilian” use of the binoculars is also indicated by the small diameter of the fixing knob (clamp) of the central hinge (see photo), which has a hole for the collar (included in the binoculars kit), with which the final fixation of the hinge was carried out depending on the interpupillary distance of the observer. On the upper disc of the hinge there is an interpupillary distance scale. Telex was produced with various design changes until 1932 in 4 versions:
1st option: 6x21, where the objective barrel and lower prismatic cover are made as one part (since 1907) and with the eyepiece case with “transverse” knurling https://binocollection.com/catalog/binocular-carl-zeiss-jena-telex-6x.html ;
2nd version: 6x21 with two-ring type objective mounts (from 1908/1909) - (see photo);
3rd version: 6x24 with dual-ring objective mounts (from 1911/1912) https://binocollection.com/catalog/binoculars-carl-zeiss-london-telex-6x.html ;
4th version: 6x24 with rounded objective caps (from 1913 to 1932) https://binocollection.com/catalog/binoculars-carl-zeiss-jena-telex-6x24.html ;
This device belongs to the 2st version, with two-ring type objective mounts. The grooves (knurling) on ??the eyepieces are perpendicular to each other (“transverse” knurling), the eyepieces have a diopter scale for sharpening. The width of the upper prismatic cover is 42.5 mm; the height of the binoculars from the lower cut of the lens frames to the upper prismatic cover is 66 mm. The diameter of the base of the eyepieces is 20.5 mm. The device’s eyecups are of the rare shape (their height is small); perhaps, they were specially made for people wearing glasses.
The inscription on the left prismatic cover of "Carl Zeiss Jena". On the right prismatic cover is “Telex 176116 6x”. The inscription is printed in block letters (early models had an italic inscription until 1904) against the background of a schematic image of a Carl Zeiss Tessar photo lens. There are inscriptions "Serichtsassessor Schutt" "Freiburg 13" on the binocular’s front prismatic covers.
The binoculars has a serial number of "176116" and was released in a batch of 300 pieces in 1908.
In 1910, the binoculars with central focusing appeared - Telexem https://binocollection.com/catalog/binoculars-carl-zeiss-jena-telexem-6x.html .
Around 1935, the Telex was replaced by a new model - the Sportur.
