Voightländer & Sohn (Vienna, Austria and
rectilinear) - c. 1880's-c.1890's
Voightländer & Sohn lenses were commonly offered as an
upgrade to house lenses (e.g., Rochester Single
The name Euryscope:
Voightländer apparently used the brand name Euryscope for most if not all
of its lenses; it may be their name for a rapid rectilinear lens.
Various series of lenses were offered, each series
representing a different lens formulation. In all series, lenses have a
number - the greater the number, the longer the focal length, as was usual for
almost all photographic lens manufacturers. In some cases, a letter is
used to distinguish between series. For example, Indermill's catalog,
above, shows an Improved Euryscope series (on the left) which appears to
be a rapid rectilinear, and also seems to be identical (in appearance) to the
Euryscope No. 5 photograph, above. On the right, a Euryscope,
otherwise un-named, is said to have a slightly changed formula, and its lenses
are designated 1A, 2A, 3A, etc. The same engraving is used to
illustrate both series.
Over time, the formulation within a given series could
change. Between 1885 and 1894, the formulation of the plain 1, 2, 3, etc.
Euryscopes changed - in 1885, the No. 5 has a 17.5" focal length, while in 1894,
the No. 5 has a 14" focal length (see above).
