Carl Zeiss SMT
Carl Zeiss SMT GmbH comprises the Semiconductor Manufacturing Technology business group of ZEISS and develops and produces equipment for the manufacture of microchips. The company is majority owned by Carl Zeiss AG, with a 24.9% minority stake by ASML Holding. The headquarters of the group are located in Oberkochen, Germany, with additional sites in the German cities Jena, Wetzlar, Rossdorf, Aachen, Coswig, Zurich (CH) Dublin (USA) and Bar Lev (Israel). In total, more than 8,500 employees work at these nine locations. History In 1968, ZEISS supplied the optics for a circuit printer for the first time. About nine years later, the world's first predecessor to a modern wafer stepper, produced by David Mann (later GCA), was equipped with optics from Carl Zeiss. In 1983, the first lithography optics from ZEISS were used in a wafer stepper from Philips. Just under ten years later, ZEISS and Philips carve-out company ASML entered into a strategic partnership.

Zeiss (company)
Zeiss ( ; ) is a German manufacturer of optics, optical systems and optoelectronics, founded in Jena, Germany, in 1846 by optician Carl Zeiss. Together with Ernst Abbe (joined 1866) and Otto Schott (joined 1884) he laid the foundation for today's multinational company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s. ZEISS is active in four business segments with approximately equal revenue (Industrial Quality and Research, Medical Technology, Consumer Markets and Semiconductor Manufacturing Technology) in almost 50 countries, has 30 production sites and around 25 development sites worldwide.

Carl Zeiss
Carl Zeiss (; 11 September 1816 – 3 December 1888) was a German scientific instrument maker, optician and businessman. In 1846 he founded his workshop, which is still in business as Zeiss (company), Zeiss. Zeiss gathered a group of gifted practical and theoretical opticians and glass makers to reshape most aspects of optical instrument production. His collaboration with Ernst Abbe revolutionized optical theory and practical design of microscopes. Their quest to extend these advances brought Otto Schott into the enterprises to revolutionize optical glass manufacture. The firm of Carl Zeiss grew to one of the largest and most respected optical firms in the world. Birth and family Carl's father, Johann Gottfried August Zeiss (1785–1849) was born in Rastenberg, where his forefathers had worked as artisans for over 100 years. August moved with his parents to Buttstädt, a small regional capital north of Weimar, where he married Johanna Antoinette Friederike Schmith (1786–18 ...

Zeiss Formula
In photographic optics, the Zeiss formula is a supposed formula for computing a circle of confusion (CoC) criterion for depth of field (DoF) calculations. The formula is c = d/1730, where d is the diagonal measure of a camera format, film, sensor, or print, and c the maximum acceptable diameter of the circle of confusion. The Zeiss formula is apocryphal, in the sense that it has grown to be a well-known named concept by propagation through the internet, even though it has no official origin, little connection to Carl Zeiss Company, and no recognition or usage in the photographic industry outside the web community. The number 1/1730 derives from a circle of confusion diameter of 0.025 mm on a full-frame 35 mm film format, with diagonal size about 43.25 mm (43.25/0.025 is 1730). The CoC size of 0.025 mm for this format appears in Jacobson's Photographic Lenses Tutorial, and the 1730 in his 1996 Photographic Lenses FAQ. Jacobson derived the 0.025 mm CoC number from analysis of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zeiss Tessar
The ''Tessar'' is a photographic lens design conceived by the German physicist Dr. Paul Rudolph in 1902 while he worked at the Zeiss optical company and patented by Zeiss in Germany; the lens type is usually known as the Zeiss ''Tessar''. Since its introduction, millions of ''Tessar'' and ''Tessar''-derived lenses have been manufactured by Zeiss and other manufacturers, and are still produced as excellent intermediate aperture lenses. The ''Tessar'' design uses four spherical lens elements in three groups, one positive crown glass element at the front, one negative flint glass element at the center and a negative concave flint glass element cemented with a positive convex crown glass element at the rear.

Zeiss Sonnar
The Zeiss Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in 1929 and patented by Zeiss Ikon. It was notable for its relatively light weight, simple design and fast aperture. Naming The name "Sonnar" is derived from the German word " Sonne", meaning sun. It was originally a tradename owned by in for a Tessar-like lens. Sontheim's coat of arms includes a symbol of the sun. Nettel merged with August Nagel's in 1919. The resulting AG in Stuttgart was one of the companies that merged to form the Zeiss Ikon AG in 1926. When the modern Zeiss lens was designed by Bertele, Zeiss re-used the old Nettel tradename in order to build on the sun association to emphasize on the lens' large aperture (), which was much greater than many other lenses available at the time.

Zeiss Planar
The Zeiss Planar is a photographic lens designed by Paul Rudolph at Carl Zeiss Carl Zeiss (; 11 September 1816 – 3 December 1888) was a German scientific instrument maker, optician and businessman. In 1846 he founded his workshop, which is still in business as Zeiss (company), Zeiss. Zeiss gathered a group of gifted p ... in 1896. Rudolph's original was a six-element symmetrical double Gauss lens design. While very sharp, early versions of the lens suffered from flare due to its many air-to-glass surfaces. Before the introduction of lens coating technology, the four-element Tessar, with slightly inferior image quality, was preferred due to its better contrast. In the 1950s, when effective anti-reflective lens coatings became available, coated Planars were produced with much-improved flare resistance. These lenses used the Zeiss T coating system, which had been invented by Olexander Smakula in 1935. They performed very well as normal and medium-long focus lenses f ...

Carl-Zeiss-Gymnasium Jena
The Carl-Zeiss-Gymnasium Jena is a state-funded German elite gymnasium school (grammar school) teaching highly gifted students in the fields of math, science, and technology. Before changing its profile to fully focus on these aspects, it was a regular German public gymnasium with a special separate school () attached to it. The school is named for optician Carl Zeiss and is located in the city of Jena in Germany's federal state of Thuringia. The school accepts students from all over the federal state. Pupils , there were about 500 students attending this school, but not all of them were enrolled in the special education program, which is restricted to highly gifted students. Entrance to the school is contingent on certain requirements, including qualification exams, grades, awards, and previous academic accomplishments. In order to enter the special education program, students in ninth grade must take an examination, the results of which determine who will be accepted int ...

FC Carl Zeiss Jena
FC Carl Zeiss Jena () is a German football club based in Jena, Thuringia. Founded in 1903, it was initially associated with the optics manufacturer Carl Zeiss. From the 1960s to the 1980s it was one of the top-ranked clubs in East Germany, won the DDR-Oberliga and the FDGB-Pokal three times each and reached the 1981 European Cup Winners' Cup Final. Since the German reunification in 1990, the club has competed no higher than the second tier. Since the 2021–22 season, Jena is playing in the Regionalliga Nordost.
