After the First world war, in accordance with the terms of the Treaty of Versailles, the optical firm "Karl Zeiss" were forbidden to manufacture any military products . To exit this position in 1921, the German company signed a secret cartel agreement with the American company Bausch and Lomb in Rochester (new York). First of all, the American company has helped its German partners to circumvent the points of the Treaty of Versailles banning military to restore German industry. Due to interest deductions, which the company Bausch and Lomb were regularly paid Zeiss in the currency of the amount of all his military orders, Zeiss built a large military optical factory in the Dutch town of Veile, near the border with Germany. The plant was in the hands of the Dutch optical company "Nadinska" and in fact is a branch of Zeiss.

Additional item secret agreement honey American firm and concern "Zeiss" includes a condition relative to placing the brand "Medynsko-Zeiss" on any product that uses Zeiss technology. Specified a cartel was of great help during the process of the remilitarization of Germany. Moreover, getting certain orders from the army and Navy, "Bausch and Lomb" immediately handed to the German partners the data of technical specifications, which constituted a military secret. "Zeiss" in turn, undertook to convey to his American partners technology proprietary trade secrets of Zeiss glass and some other products in exchange for a seven percent royalty on all sales of military products (except field glasses). All these agreements were reached privately, officials were only notified the us naval attaché in Berlin and then only in part directly related to the fleet.

Moreover, these two companies have divided among themselves the whole international market for military optics, and a dominant role in the resulting cartel played "Zeiss" and his influence was so great that he was appointed the chief of military products in the "Bausch and Lomb" (in fact , the person acted as the agent of the German military and technical intelligence in the US). The company Bausch and Lomb has focused on the supply of optical instruments in USA, the same firm Zeiss had to provide military optics in the world. As a result, when before the Second world war Britain, France and other countries turned to an American company with orders for military optical instruments, she said that she downloaded the orders of the army and Navy of the US and kindly recommended to refer to "Nadinska", i.e. to the Germans. As a result, after the start of the war the British, the French were without optical devices. There is evidence, and procurement of the USSR military optical instruments of the firm "Nadinska" in the prewar period, in particular on the supply in the USSR scopes in 1929. On the delivery of military binoculars while documentary evidence no, but there is some indirect evidence of this. In particular, the presence in the extant samples of binoculars 8x30 a coward all Golan production 1926 the manufacture of the angular grids , as approved by the GAU in 1913 the sample used in that period in the USSR, as well as the presence of casings brass half-rings for additional fastening of boxes to camping gear, also taken at the beginning only in the Russian Imperial army and later in the red army. In addition, certain proof of the use of such binoculars in the red army is the presence in the collections of these binoculars with the repair scenes of Soviet artillery bases. Judging by the numbers on the remaining binoculars, supplied to the USSR 8x30 binoculars was not less than 3000 pieces.

After Hitler came to power in Germany, design centres and factories Zeiss were closed to American partners. At the same time, Bausch and Lomb both before and after the start of the war in Europe continued to send detailed information about their technical achievements and the orders of the American army and Navy. These data have allowed Hitler's General staff to monitor the quantitative and qualitative development of the American artillery, air force and submarine fleet. In 1940, the U.S. Department of justice and the Senate Committee headed by Harry Truman, acting in the interests of state-monopoly complex eliminated the American-German optical cartel as threatening to U.S. national security.
