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 Carl Zeiss AG. 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 His 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 (1786–1856). Carls ...

Emil Zeiß
Emil Zeiß (2 July 1833 – 14 April 1910) was a German Protestant minister and painter. His body of work includes 33 sketchbooks and 1092 identified individual works, largely donated by his son to the Lippe Museum. Life Zeiß was born in the village of Stapelage in North Rhine-Westphalia. He attended the University of Marburg. On 30 November 1859 he was admitted as a candidate for ministry in the Reformed church after passing the first theological examination.

Carl Zeiss AG
Carl Zeiss AG (), branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss.

Schott AG
Schott AG is a German multinational glass company specializing in the manufacture of glass and glass-ceramics. Headquartered in Mainz, Germany, it is owned by the Carl Zeiss Foundation. The company's founder and namesake, Otto Schott, is credited with the invention of borosilicate glass. History Founding In 1884, Otto Schott, Ernst Abbe, Carl Zeiss and his son Roderich Zeiss founded the ''Glastechnische Laboratorium Schott & Genossen'' (Glass Technical Laboratory Schott & Associates) in Jena, which initially produced optical glasses for microscopes and telescopes. In 1891, the Carl Zeiss Foundation founded two years earlier by Ernst Abbe became a partner in the glass laboratory. Jena glass, an early borosilicate glass, was one of its early manufactured products. The invention of borosilicate glass, resistant to chemicals, heat and temperature change, paved the way for new technical glasses for thermometers, laboratory equipment and gas lamps.

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeiss Projector
A Zeiss projector is one of a line of planetarium projectors manufactured by the Carl Zeiss Company. Main models include Copernican (1924), Model I (1925), Model II (1926), Model III (1957), Model IV (1957), Model V (1965), Model VI (1968), Spacemaster (1970), Cosmorana (1984), Skymaster ZKP2 (1977), and Skymaster ZKP3 (1993). The first modern planetarium projectors were designed and built in 1924 by the Zeiss Works of Jena, Germany in 1924.Christopher Dewdney. Acquainted with the Night: Excursions Through the World After Dark'. Bloomsbury Publishing USA; 2005 ited 14 October 2011 . p. 278–279. Zeiss projectors are designed to sit in the middle of a dark, dome-covered room and project an accurate image of the stars and other astronomical objects on the dome. They are generally large, complicated, and imposing machines. The first Zeiss Mark I projector (the first planetarium projector in the world) was installed in the Deutsches Museum in Munich in August, 1923. It poss ...

Zeiss Planar
The Zeiss Planar is a photographic lens designed by Paul Rudolph at Carl Zeiss in 1896. Rudolph's original was a six-element symmetrical 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 for small and medium format cameras. One of the most notable Planar lenses is the high-speed 2.0/110 mm lens for the 2000- and 200-series medium format Hasselblad cameras.
