Thanks, George. Last edited by a moderator: Oct 3,

Easy, fast, intelligent: the modern way to order lenses.

Hello to the community, as a youngster to this very special forum, I am coming up with a marginal problem. When was this one produced? As far as I understand, Carl Zeiss Jena introduced lens coating T some time in , but not covering the whole production, and after the coating process was declared “eyes only” and attached to military purposes, mainly with the German marines, so that very few if any coated lenses reached the wartime civilian market.

We are talking here about West German manufacture, as opposed to the East German Carl Zeiss Jena lenses that were budget options for the Praktica and other low-cost cameras.

First a little background. The company of Carl Zeiss also ended up being divided and eventually this settled into two Zeiss companies, totally unrelated, but stemming from the same roots. The East German factory at Jena became the home of the lenses for Praktica and other low-cost cameras, at one time one of the best affordable options for the average amateur photographer. The relevance of this is that eventually Zeiss and Voigtlander came together and in the Icarex 35S was born, designed originally by Voigtlander but now labelled Zeiss by its new owners.

It was never our intent to write one comprehensive and all-encompassing history of Zeiss, that would require volumes to do it justice, but rather to explain why we at Company Seven remain grateful for and in awe of the achievements by Zeiss.

These aims and the following principles determine the policy of the foundation companies: science and technology complement each other; science, technology and economics serve man and not vice versa; economic stability safeguards jobs; the company and its employees are mutually dependent. Science, progressive technology and social responsibility are therefore the main objectives behind the activities of the Carl-Zeiss-Stiftung.

These enterprises develop, produce, and sell high-quality precision-engineered optical glass and electronic products, including ophthalmic products, binoculars, camera lenses, medical and surgical instruments and systems, microscopes, semiconductor technologies, measuring machines, surveying instruments, glass for household appliances, consumer glassware, laboratory glassware, glass tubing, and glass pharmaceutical packaging. The company has no private or state associates, and no shareholders.

Stiftung is sometimes inaccurately translated as a special type of ‘foundation,’ a term suggesting an institution with purely charitable or scientific aims.

Usually companies are owned by individuals, banks, or states. The above-mentioned enterprises, however, are owned by the Stiftung and owe much of their character to its statute provisions.

These improved microscopes sold from , and–in particular microscopes with homogenous immersion objectives, introduced in , and those with apochromatic objectives, available in greatly assisted bacteriologists’ identification of infectious bacteria.
