Rodenstock GmbH
Rodenstock GmbH is a German 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 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. The eyeglasses division is now owned by the European holding company Bridgepoint. These independent entities still operate with the same stylized "R" logo.
Rodenstock generations
Josef RodenstockOn 1 January 1878, Josef Rodenstock, a peddler of self-designed measuring instruments and spectacle frames from Thuringia, began business operations together with his brother Michael of the company "G. Rodenstock" which had been founded in Würzburg in 1877.
Alexander Rodenstock joined the company at the age of 22 in 1905. He had given up his studies of physics and economics at the urging of his father and started to prepare to take over the management of the family company; he did so in 1919.
Rolf Rodenstock
Rolf Rodenstock had a diploma in general business, a doctorate and a professorship. He took over the helm of the family company from his father in 1953. He supervised the reconstruction of the company and Rodenstock’s own "economic miracle" and was considered one of the most respected corporate personalities of the still young Federal Republic.
Randolf Rodenstock joined the company in 1976 and initially managed the company together with his father following his study of physics at Munich University and a subsequent MBA at the INSEAD management school in Fontainebleau, France. He took over general responsibility for the company in 1990 and focused the company on the demands of increasing industrial globalization.
Ophthalmic products
More than 135 years of tradition, experience and the associated know-how have made Rodenstock into one of the most important manufacturers of lenses and frames. Rodenstock is the only brand that delivers “spectacles from a single source” with frames and lenses as a complete provider and is the inventor of the first individual progressive lens Impression®as well as the technology EyeLT®. The frames collection of Rodenstock has been allocated with more than 50 awards.
The competence for both ophthalmic lenses as well as for frames makes Rodenstock into a unique brand in ophthalmic optics because it can offer spectacles wearers the complete ”spectacles” system from a single source. Besides frames and lenses Rodenstock develops and sells video-centration systems under the brand name ImpressionIST as well as consulting software.

Geronar
The least expensive of the Rodenstock lenses, these 3-element, 3-group designs have a 60° angle of view, and perform best when stopped down.- 90 mm f/8
- 150 mm f/6.3
- 210 mm f/6.8
Eurynar
Their formula was changed from double-gauss to dialyt somewhere between number 116.000 and 239.000, but there were still some double-gauss-Eurynar's, where a greater angle was necessary.
The Lens Collector's Vade Mecum is giving 1924 as the date for this change.
At 1930 there was also a double anastigmat Eustigmat 1:6.8/135mm, which looks like a double-gauss Eurynar.
Kadlubek's Lens Catalogue is showing up 13 sizes from 90mm to 600mm, with f4.5, f5.4, f5.6, or f6.8;
the Vade Mecum is listing sizes from 50mm to 600mm and additional openings f3.5, f3.8, f4.0, and f6.5.
Typically 135mm is used for 9x12cm, 21 cm for 13x18 / 7x5in, 42 cm for 10x8in, 48 cm for 12x10in and
60 cm for 15x12in.
Grandagon-N
The Grandagon lines are Rodenstock's wide-angle lenses. With an angle of view of 105°, these 8-element, 4-group lenses are the standard wide angles of the Rodenstock line. In their respective focal lengths, they are among the fastest wide angles available from any manufacturer. The 90;mm f/6.8, by contrast to the rest of the line, is a 6 element design.- 65mm f/4.5

APO-Ronar
Only some barrel Apo-Ronars can be remounted into a shutter, for details see http://www.skgrimes.com/lens-mounting/table-of-lenses-fitted-to-shutters.
Most barrel APO-Ronars have a slot that allows to insert gel filters and waterhouse stops of any shape between the two optical groups, but there are also APO-Ronars with a fixed f-stop, i.e. a circular plate instead of an iris, and no filter slot.
Lengths above 240mm also have a millimeters iris scale that indicates the real iris diameter, in order to calculate with high precision the effective f/stop when you work in close up and repro photography. This scale is typically starting at 2mm corresponding to a f-stop of 120 for a 240mm lens. Such and even higher values are useful for and only for prepress use.
The CL-Versions have a linear f-stop scale. This is useful for setting precise f-stops, specially when often different values are used.
