Ernst Leitz Wetzlar Microscope Serial Numbers

Company Seven Carl Zeiss Companies History. Zeisss Inspirational Planetariums among the areas of prominent growth in the sciences at the time was the field of astronomy. As the demand grew for larger and more complicated telescopes and mountings, this could be met only by a firm with well integrated resources including Zeiss. One of the technologies that Zeiss pioneered and dominated before World War II, was the development and production of planetarium instruments. A planetarium instrument is housed in the center of a room with a hemispherically domed ceiling. The instrument projects points of light and images of deep sky objects onto the ceiling to simulate the night sky from various perspectives including seasonal, or historical views of the Earth sky relationship. These instruments were single handedly responsible for motivating many young people to explore and to better comprehend astronomy and celestial navigation. In the years before World War I, Carl Zeiss Jena was approached by Oskar von Miller and other planners of the Das Deutsche Museum The German Museum of science and technology in Munich. They asked Zeiss to propose a design for a new educational instrument to teach astronomy at their forthcoming larger facility.

World War I delayed the development but commencing immediately after in 1. Bauersfeld led the team to construct a unique projector, and it was he who managed the team that created the first modern planetarium. This first projection planetarium was constructed at the Zeiss Jena factory and was demonstrated there to the museum directors before dismantling, transportation and final installation.

It was located at the new Deutsches Museum von Meisterwerken der Naturwissenschaft und Technik German Museum for Masterpieces of Natural Science and Technology at Munich, Oskar von Miller formally opened the new museum on 2 May 1. The original instrument was designed to reflect the sky above Munich and it created such a sensation that Zeiss was giving demonstrations to military, ocean navigational companies and countless others there. What had been an engineering exercise to create a special instrument for a single museum became a great product for education and inspiration. In part as a technology demonstrator and also as a part of the Stiftungs sense of civic duty, the Zeiss Planetarium Jena was completed and inaugurated on 1.

Nov. 1. 95. 8 had been among the Zeiss employees involved with the project. While Kisshauers doctorate was in political science, he was however an experienced amateur astronomer and member of the Astronomical Society and so his practical experience was beneficial for the project. By 1. 92. 6 Kurd Kisshauer had left Zeiss and moved to Dresden where later in 1. Carl Kellner founded what was named the Optical Institute in Wetzlar Germany in 1849. By 1851 he employed twelve workmen and was producing his first microscopes. Director of the newly completed Municipal Planetarium Dresden. Major cities around the globe wanted their own planetarium and so Bauersfelds team modified the original design so that it would be able to represent the skies over any point on the globe. Where ever there planetarium instruments were installed they became a source of civic pride. And these sales were a source of revenue for a company that was working hard to survive the great depression. Open .Emc File Format here. Even after World War II both Zeiss companies would establish planetarium production at their headquarters, and their domes would figure prominently in the skyline of their factories. Even though after the second world war these were never really a profit center for Zeiss, it was a matter of social responsibility and corporate pride that inspired Zeiss to continue production. This may have had something to do also with the leadership and influence of Dr. Bauersfeld, who had been deeply involved with the development of astronomical telescopes, their mounts, and instruments. Since 1. 92. 7 Bauersfeld had also taught Astronomical Physics and Engineering Mechanics as an Associate Professor, and from 1. Professor Professor ordinarius at the University of Jena. Germany Helping The People Who Would Later Eat Their Lunch Nikon of Japan was formed when three leading optical manufacturers in Japan merged to form Nippon Kgaku Kgy Kabushikigaisha, or Japan Optical Industries Corporation. The company became known in many areas including the production of optical and measuring equipment, binoculars, small telescopes and even larger and more complicated astronomical telescopes. Moving into the 1. Nikon worked to produce more sophisticated camera lenses but the company, lacking engineering know how, ran into roadblocks. So by 1. 92. 1 Nippon Kogaku persuaded eight German optical engineers to come to work for the company. These engineers including Heinrich Acht, Hermann Dillmann and Max Lange, were instrumental in helping to get Nippon Kogaku onto the right track. A series of lenses whose designs were modeled on the Zeiss Tessor were designated Anytar lenses. Seven of the German engineers returned home in 1. Acht remained until 1. Kakuya Sunayama, the General Manager of the Lens Design Department, visited Germany to learn more about optics. Mr. Sunayama acquired a Carl Zeiss 5. F4. 8 Triplet three element lens. The Zeiss lens was disassembled, studied, and essentially copied so that by 1. Nippon Kogaku had completed their first prototype camera lens and designated this the Tessor type Anytar 5. F4. 5. This lens was followed by the Anytar 1. F4. 5 at the end of 1. By 1. 93. 0 the Triplet, the Tessor and the Dagor type lenses were in production. Improving upon the original designs by 1. Anytar 1. 2cm F4. Zeiss Tessor. With the prospects for developing a system of photographic lenses it was decided to market them under a unifying name, thus the NIKKOR brand was born in 1.

By 1. 85. 0 Hensoldt formed his own company M. Hensoldt Soehne AG for the manufacture of optical instruments. By 1. 92. 8 the Hensoldt company, with its factory in Wetzlar, had the Carl Zeiss company as a shareholder. Zeiss thereby acquired a partnership with a manufacturer best known for their roof prism binoculars introduced in 1. Dialyt series of Abbe Koenig in line prism binoculars and riflescopes. Hence the similarity between the appearance of traditional Hensoldt roof prism binoculars made since about 1. Carl Zeiss roof prism products up to today. Improvements continued, including the 1.
