👉 Schott AG in the context of Carl-Zeiss-Stiftung
The Carl-Zeiss-Stiftung (Carl Zeiss Foundation), legally located in Heidenheim an der Brenz and Jena, Germany, and with its administrative headquarters in Stuttgart, is the sole shareholder of the two companies Carl Zeiss AG and Schott AG. It was founded by Ernst Abbe in 1889 and named after his long-term partner Carl Zeiss. The products of these companies include the classic areas of optics and precision mechanisms, as well as glass (including optical glass), optoelectronics, and glass ceramics. The statutes of the foundation emphasize the social responsibility of the companies and the importance of a fair treatment of the employees.
In fiscal year 2007/2008 more than 30,000 people were employed by the foundation's companies and their subsidiaries, with total sales of over 4.9 billion Euros.

Schott AG in the context of Carl Zeiss AG
Zeiss (/zaɪs/ ZYSE; German: [kaʁl ˈtsaɪs]) is a German manufacturer of 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 AG is the holding company for all subsidiaries within the Zeiss Group, of which Carl Zeiss Meditec AG is the only one that is traded on the stock market. Carl Zeiss AG is owned by the Carl-Zeiss-Stiftung foundation. The Zeiss Group has its headquarters in southern Germany, in the small town of Oberkochen, with its second largest, and founding site, being Jena in eastern Germany. Also controlled by the Carl-Zeiss-Stiftung is the glass manufacturer Schott AG, located in Mainz and Jena. Carl Zeiss is one of the oldest existing optics manufacturers in the world.
Schott AG in the context of Jena
Jena (/ˈjeɪnə/; German: [ˈjeːna] ) 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 of Jena (formally the Friedrich Schiller University) was founded in 1558 and had 18,000 students in 2017 and the Ernst-Abbe-Hochschule Jena serves another 5,000 students. Furthermore, there are many institutes of the leading German research societies.
Jena was first mentioned in 1182 and stayed a small town until the 19th century, when industry developed. For most of the 20th century, Jena was a world centre of the optical industry around companies such as Carl Zeiss, Schott and Jenoptik (since 1990). As one of only a few medium-sized cities in Germany, it has some high-rise buildings in the city centre, such as the JenTower. These also have their origin in the former Carl Zeiss factory.
Schott AG in the context of Nordic Optical Telescope
The Nordic Optical Telescope (NOT) is an astronomical telescope located at Roque de los Muchachos Observatory, La Palma in the Canary Islands. The telescope saw first light in 1988, and was officially inaugurated during September 1989. Regular observing started in 1990. It is funded by Denmark, Sweden, Norway, Finland, and (since 1997) Iceland. Access is provided directly to astronomers of the funding countries, and of all nationalities through international time allocation committees.
The main mirror has a diameter of 2.56 metres (101 in). The optical forming was done at the optical laboratory at the Tuorla Observatory, on mirror blanks made of Zerodur at Schott Glaswerke in Mainz, Germany.
Schott AG in the context of Borosilicate glass
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 K at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials of about 330 °F (166 °C) without fracturing. It is commonly used for the construction of reagent bottles and flasks, as well as lighting, electronics, and cookware. For many other applications, soda–lime glass is more common.
Borosilicate glass is sold under various trade names, including Borosil, Duran, Pyrex, Glassco, Supertek, Suprax, Simax, Bellco, Marinex (Brazil), BSA 60, BSC 51 (by NIPRO), Heatex, Endural, Schott, Refmex, Kimax, Gemstone Well, United Scientific, and MG (India).
