in the design
of photogrammetric instruments
After production of photogrammetric instruments
had been resumed in West-German Zeiss Works, the
high-performance
ZEISS TOPAR LENS
was developed. Excellent image resolution, superb
illumination up to the very corners of the negative,
color-corrected, maximum distortion of t4microns-
these are the characteristics of pictures taken with
our 8 1/4" Aerial Survey Cameras RMK 21/18 and
2 x RMK 21/18 (Convergent Camera).
ZEISS-AEROTOPOGRAPH MUNICH
München 27/ Western Germany / Ismanmgerstr. 57
with an aperture of f/5.6, for focal lengths of 4 1 /2"
and 6”. Superb image resolution, 100% better illu
mination in the corners as compared to the Topogon
lens, maximum distortion of ± 4 microns make the
Pleogon superior to all other lenses with an angular
field of 100 9 .
Full utilization of the excellent resolving power of
the Topar and Pleogon high-performance lenses is
guaranteed by the temperature-proof
ZEISS AEROTOP SHUTTER
Continuously rotating discs result in especially high
light efficiency. Image movement largely eliminated
through continuous setting of exposure times up to
1/500 and/or 1/1000 sec.
Of more than 200 Stereoplanigraphs over 60 are
working with coordinate printing counter. The fact
that each new series of
C 8 STEREOPLANIGRAPHS
is being equipped with this printing counter, has
contributed to the extensive use of this instrument
for large-scale high-precision photogrammetry and
aerotriangulation. For topographic mapping at small
and medium scales, the Stereotope has rendered
excellent service in the photogrammetric practice.
