The history of the brand DOCTER

History of binoculars and the company before 1945

The history of binoculars is inseparably linked to the company Carl Zeiss, to which also the roots of our product history go back. Binoculars, the most common kind of terrestrial telescopes, meanwhile have got a tradition of more than 100 years, the foundations of binoculars in the form known today having been laid by the company Carl Zeiss on July 9th 1893 with the Deutsche Reichspatent No. 77086 "Double telescope with increased objective distance". Already in this year the first so-called "double field glasses" were made. Approximately at the same time, 1892, the first sights for rifles originated.

The company Carl Zeiss took a decisive part in the rapid development that followed for this line of production. 10,000 prism binoculars were produced here up to 1900. In 1903 the first spotting scope was presented. In 1919 the first binoculars with wide angle eyepieces (70 degree apparent field of view) appeared. In 1920 new sights with lens erection system for hunting were on offer for the first time. Already in 1922 the first sights with variable magnification were introduced by Zeiss. In 1926 binoculars with in-line optics and roof edge prisms were added to the product range. In 1936 Zeiss introduced reflection-reducing optical layers for increasing the light transmission for these products. In the 30s and 40s the development of visual observation and sight devices reached a climax, due to the forced arms development of World War 2. A very wide spectrum of devices was already on offer, which was expanded by a multitude of military models during the years of the war. At this point aspherics were already used and magnesium was employed for the case.
