Selon Charlie Barringer, la chronologie de Edward Kaprelian, comme publie dans The Lens Collector's Vade Mecum, est plus ou moins correcte. La voici:
!890 Anastigmat production begins. this is partly licensed to others, including Voigtlaender for
Germany.The earliest Zeiss Anastigmat noted so far is No1,51x suggesting a possible No1000 start at Jena
for camera lenses: but note an aplanat for projection seems anomalous.
1895 Voigtlaender stops production of Zeiss designs, suggesting Zeiss had expanded production facilities
to make the lenses at Jena.
1900 c. 44,040 as Unar sales begin, production of anastigmats reaches 100,000, with about 44,000 by
Zeiss and 56,000 under license.
1902 Tessar f6.3 launched. This must have been one factor leading to a big expansion of demand and
production.
1908 91,711 + 103,3xx, 104,2xx noted on cameras burgled at N&G, London (Manthos article), but note
N&G may have lagged in fitting as cameras made in 1912 had lenses No133,73x- say a year in store or
transit.

I believe that Arne Croell, who posts on usenet and http://www.largeformatphotography.info/lfforum/
has access to more data
