Jena is a city in Germany and the second largest city in Thuringia. Together with the nearby cities of Erfurt and Weimar, it forms the central metropolitan area of Thuringia with approximately 500,000 inhabitants, while the city itself has a population of about 110,000. Jena is a centre of education and research; the university was founded in 1558 and had 18,000 students in 2017 and the Ernst-Abbe-Fachhochschule Jena counts another 5,000 students. Furthermore, there are many institutes of the leading German research societies.
Carl Zeiss 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.
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. Together with Ernst Abbe and Otto Schott 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 in almost 50 countries, has 30 production sites and around 25 development sites worldwide.
Ernst Karl Abbe was a German businessman, optical engineer, physicist, and social reformer. Together with Otto Schott and Carl Zeiss, he developed numerous optical instruments. He was also a co-owner of Carl Zeiss AG, a German manufacturer of scientific microscopes, astronomical telescopes, planetariums, and other advanced optical systems.
Saxe-Weimar-Eisenach was a German state, created as a duchy in 1809 by the merger of the Ernestine duchies of Saxe-Weimar and Saxe-Eisenach, which had been in personal union since 1741. It was raised to a grand duchy in 1815 by resolution of the Congress of Vienna. In 1903, it officially changed its name to the Grand Duchy of Saxony, but this name was rarely used. The grand duchy came to an end in the German Revolution of 1918–19 with the other monarchies of the German Empire. It was succeeded by the Free State of Saxe-Weimar-Eisenach, which was merged into the new Free State of Thuringia two years later.
Schott AG is a German multinational glass company specializing in the manufacture of glass and glass-ceramics. Headquartered in Mainz, Rhineland-Palatinate, 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.
The Deutsches Optisches Museum Jena is a science and technology museum displaying optical instruments from eight centuries. It gives a technical and cultural-historical survey of the development of optical instruments. The development of the city Jena to the centre of the optical industries since the mid-19th-century is integrated in the exhibition, connected with the lifeworks of Ernst Abbe, Carl Zeiss and Otto Schott. In cooperation with the art club Jena non-optical themes are offered in special exhibitions. Before the opening of the Zeiss Museum of Optics in Oberkochen in 2014, the Deutsches Optisches Museum Jena was the only museum of its kind in Germany.
An Abbe refractometer is a bench-top device for the high-precision measurement of an index of refraction.
Jenoptik AG is a Jena, Germany-based integrated photonics company. The company is listed on the Frankfurt Stock Exchange and is included in the TecDAX stock index.
Friedrich Otto Schott (1851–1935) was a German chemist, glass technologist, and the inventor of borosilicate glass. Schott systematically investigated the relationship between the chemical composition of the glass and its properties. In this way, he solved fundamental problems in glass properties, identifying compositions with optical properties that approach the theoretical limit. Schott's findings were a major advance in the optics for microscopy and optical astronomy. His work has been described as "a watershed in the history of glass composition".
Siegfried Czapski was a German physicist and optician.
The Ernst Abbe Sportfeld is a sports facility in Jena, Germany. The main stadium at the sports facility is the Stadion in Jena. It was dedicated on 24 August 1924 and was named after entrepreneur Ernst Abbe 15 years later. The facility is in southern Jena, directly on the Saale River. The City of Jena purchased the stadium from the Ernst-Abbe-Stiftung in 1991.
August Karl Johann Valentin Köhler was a German professor and early staff member of Carl Zeiss AG in Jena, Germany. He is best known for his development of the microscopy technique of Köhler illumination, an important principle in optimizing microscopic resolution power by evenly illuminating the field of view. This invention revolutionized light microscope design and is widely used in traditional as well as modern digital imaging techniques today.
The calculation of glass properties is used to predict glass properties of interest or glass behavior under certain conditions without experimental investigation, based on past data and experience, with the intention to save time, material, financial, and environmental resources, or to gain scientific insight. It was first practised at the end of the 19th century by A. Winkelmann and O. Schott. The combination of several glass models together with other relevant functions can be used for optimization and six sigma procedures. In the form of statistical analysis glass modeling can aid with accreditation of new data, experimental procedures, and measurement institutions.
