Rodenstock GmbH ((:ˈʁoːdn̩ʃtɔk)) is Germany's leading manufacturer of ophthalmic lenses and spectacle frames. The company, which was founded in 1877, is headquartered in Munich. It has a worldwide workforce of approximately 4,200 and is represented in more than 80 countries with sales subsidiaries and distribution partners. Rodenstock maintains production sites for ophthalmic lenses at a total of 14 locations in 12 countries. == History == The foundation for Rodenstock's development was laid in 1877 by Josef Rodenstock with his workshop and shop for lenses, frames, barometers, and measurement instruments in Würzburg. In 1880, he developed his first patented products – diaphragm lenses. Two years later, he started exporting internationally and founded his own production sites. Since 1883 the company’s headquarters is located in Munich. In the new millennium, the ophthalmic optics company quickly developed from a small tradesman shop into a modern industrial enterprise. For example, the first bifocal lenses came from Rodenstock as did UV-absorbing lenses. In addition to the production of lenses, the third generation put special focus on the manufacture of frames. In 1955, Rodenstock sold more than one million of them. Other innovations followed like, for example, self-tinting (phototropic) lenses and the first progressive lenses developed by the company, the Progressiv R, which was an immediate success in the 1980s. In the 1990s, the unique selling point as a manufacturer of lenses and frames from a single source was consistently developed. Through continuous innovations, Rodenstock further expanded its market share during that time. In 2000, the company landed a real coup in the field of individual progressive lenses with the product ImpressionILT. Rodenstock invented the modern progressive lens. In 2000, the precision-optics division, Rodenstock Precision Optics, was sold to LINOS AG, which itself was subsumed by Qioptiq group in 2010 making Rodenstock Precision Optics a brand of Qioptiq.〔http://www.rodenstock-photo.com/en/main/company/〕 The eyeglasses division is now owned by the European holding company Bridgepoint.〔http://www.rodenstock.com/rodb2c/uk/en/1188032/docId-1185664/About%20Rodenstock/Organisation/Organisation.html〕 These independent entities still operate with the same stylized "R" logo. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rodenstock GmbH」の詳細全文を読む スポンサード リンク
