There is also an inscription “Telexem 1309732 6x24” on the right prism cover. There are inscriptions “Carl Zeiss Jena Jena” on the left prism cover. These binoculars are very solid and proof- and watertight, the optical performance is extremely good. The eyepieces’ housing and the eyecup design were also changed (see photo). KRIEGSMARINE U-BOAT DECK MOUNTED BIGEYE BINOCULARS - CARL ZEISS JENA 10 X 80 -20° These binoculars were used aboard the German Kriegsmarine with the flak anti-aircraft guns. The binocular’s field of view is 8.5° (it was equal to 6.8° in the previous version). The eyepieces’ base diameter is equal to 24 mm(this value was equal to 20.5 mm in previous version of this model). The prism covers are attached to the housing with the help of one screw (there were three screws in the previous version ). The upper prism cover width is equal to49 mm (this value was equal to 45.5 mm in previous version of this model) the binoculars’ height from the lens frames’ lower cut to the upper prism cover is equal to 69 mm. The eyepieces grooves (knurling) are located along the binoculars’ optical axis. This device belongs to later version (with an objective equal to 24 mm), having rounded objective covers. The right eyepiece has its own focusing mechanism with a diopter scale. The diopter scale is plotted on the central focusing flywheel (the first models did not have it). The binocular “civilian” use is proved by central focusing mechanism (military models were never produced with it).There is an interpupillary distance scale on the upper hinge disc. Since 1921 the binoculars’ field of view was increased from 6.8° to 8.5°. The first Telexem models’ objective diameter was equal to 21 mm and since 1911/12 –it was 24 mm. Subsequently, all civilian Carl Zeiss binoculars with central focusing had an “.em” ending in their designations. First models of central-focus binoculars appeared in T136 catalog in 1910–those were Teletur 6x15, Telexem 6x21, Telactem 8x24 and Silvarem 6x30. First prototypes of these binoculars were produced in Jena back in 1907, but only in 1909/1910 Carl Zeiss was forced to begin mass production of the devices of such design under the competitors’ pressure and because of the demand. Carl Zeiss engineers were not in a hurry with such devices’ production, since they considered them less reliable and protected from dust and dirt. Binoculars with central focusing appeared on the market in the middle of the 19th century.
