Design variations. Most Zeiss lenses other than the mm mirror lens had the same design style, so when changes of styling were introduced, they were phased in to all other Zeiss lenses except the mirror lens. When buying any camera with inter-changeable lenses, bear in mind that the lens may not be the one that was on the camera when it was new. This Praktisix II was manufactured between and , but the Tessar lens shown here was last produced in the Praktisix mount in February It would have been fitted to the original version of the Praktisix.
The makers of the Praktisix decided that the camera would sell better if it had the option of a more prestigious standard lens than the four-element Tessar, although we should not forget that at the time the first Hasselblads were also being supplied in many markets with a Tessar lens. However, the Meyer-Optik Primotar continued to be offered as an economical alternative for a number of years.
The first 80mm Biometars for the Praktisix had the same cosmetic style as the Tessar illustrated above — mostly alloy, with a black leather focussing band. However, some of the lenses later in the same production run! The lens illustrated on the right here was part of that first production run.

Many of these people are completely dependent on these lenses to live a normal, full life. In order to support their partner opticians, ZEISS run regular campaigns and promotions, awareness for which had traditionally always been driven via offline channels alone.

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. The Carl-Zeiss-Stiftung, however, is a business organization with specific technological, scientific, economic, and social aims and functions. 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.
The origins of the Carl-Zeiss-Stiftung date from , when Carl Zeiss, later awarded the title of university mechanic by the Grand Duke of Sachsen-Weimar, opened an instrument maker’s shop in Jena. He soon specialized in the manufacture of microscopes. At the request of Carl Zeiss, the physicist Ernst Abbe developed the wave theory of microscopic imaging and, based on this theory, designed instruments with better resolution power and better color rendition than was hitherto possible.
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. At that time the availability of only a small number of glass types with different optical properties limited progress in microscope image quality.

Method and apparatus for determining the location of the ocular pivot point. Patent number: Abstract: The invention relates to a method and an apparatus for determining the location of at least two optical parameters of an eye of a test person. In the method, at least two optical parameters of an eye having a reference structure are photographically recorded to determine in each case one of the optical parameters of the eye.
The apparatus for determining at least two optical parameters of an eye having a reference structure is provided with separate recording units for photographically recording the eye for the determination of in each case one of the optical parameters of the eye. Type: Grant.

The Zeiss Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in  and patented by Zeiss Ikon. The name “Sonnar” is derived from the German word ” Sonne “, meaning sun. The first Zeiss production Sonnar was a Compared to Planar designs the Sonnars had more aberrations , but with fewer glass-to-air surfaces it had better contrast and less flare.
Though compared to the earlier Tessar design, its faster aperture and lower chromatic aberration was a significant improvement.
