These two lines began to diverge in the 1960s as the center of photographic lens manufacturing shifted to Japan; the ophthalmic business continued as Rodenstock GmbH while the remaining camera lens business was repositioned to serve the large format and industrial precision optics markets, then spun off in 1996 as Rodenstock Präzisionsoptik.
Since then, the precision optics brand has been acquired in succession by LINOS Photonics (Göttingen, 2000), Qioptiq Group (Luxembourg, 2006), and Excelitas Technologies (2013).

At about the same time in the mid- to late-1950s, Rodenstock was supplying lenses to Carl Braun Camera-Werk (for the Colorette Super II and Paxette Reflex) and Iloca (for the Electric).
