Point Transfer and Marking Device. For quick and exact transfer and 
marking of points specially used for aerotriangulation, radialtriangulation 
and other photogrammetric procedures. 
Instruments for Plotting of Single Photographs and Production 
of Mosaics 
Rectifier SEG V. For enlargement and rectification of aerial photographs 
up to 23 cm. x 23 cm. (9 in. x 9 in.) within the range of 0-5 to 6-5 times. 
The first Rectifier with which the perspective condition is fulfilled by 
calculators with electronic control of all relevant settings. Thus, only 
three of the five orientation elements remain to be set individually. The 
instrument is introduced in many countries of the world. The Rectifier 
SEG V is now equipped with an electromagnetic shutter tripping device, 
which is easily operated from a switchboard including an exposure timer 
to be attached to the easel. 
Aero Sketehmaster LUZ. A well-known instrument for the completion 
and correction of existing maps on the basis of aerial photographs. 
Radial Secator RS I. For plotting of control points to be used in rectifica 
tion according to the slotted template method. A two-stage slot cutter with 
special device for automatic correction of picture tilt up to 25 g as well as 
for variation of scale between photograph and template from 05 to 2 times; 
complete with all accessories for the lay-out of slotted template 
triangulation. 
Radial Secator RS II. A simple slot cutter for mechanical radialtriangula 
tion of small areas, used also for training purposes. Slots are cut in the 
aerial pictures themselves or in templates provided with the respective 
marks. Complete accessory same as for Radial Secator RS I. 
Instruments for Aerial Interpretation 
Pocket Stereoscope. Handy folding stereoscope for the observation of 
stereo views up to a size of 6 cm. x 13 cm. (2-36 in.x5T in.), and for 
examining parts of large aerial photograph pairs; it is also suited for the 
observation of stereo views in books and magazines. 
Field Outfit for Aerial Photograph Interpretation. Leather carrying case 
with pocket stereoscope equipped with magnetic feet, stainless steel picture 
plate. The equipment contains furthermore all writing and drawing acces 
sories which are necessary for field work. 
Bridgetype Stereoscope. Answering higher demands for the observation 
of all kinds of stereo views and especially for air photo interpretation. 
Large telescopic bridge with adjustable magnifier holders and two inter 
changeable sets of magnifiers 2-times and 4-times. The magnifier separa 
tion can be adjusted individually for the observer within a range of 50 mm. 
to 76 mm. (2 in. to 3 in.).

Mirror Stereoscope. The approved mirror stereoscope for examination of 
large-size picture pairs, observation basis 26 cm., observation field about 
18 cm. x 20 cm. 4-times or 6-times monoculars with adapter can be used 
for the examination of picture detail. 
Mirror Stereoscope OV. With convenient oblique eyepieces, observation 
basis 21 cm. The mirror stereoscope OV is used as the observation 
instrument for the Stereotope and Stereopret. 
Tracing Stereometer. Parallax-bar with measuring marks and tracing 
device used for the determination of x-parallaxes, i.e. relative height 
differences such as tree heights, slopes, etc., and for tracing planimetry and 
form lines. 
Stereopret. Instrument for stereoscopic interpretation and sketching from 
vertical photographs up to a size of 23 cm. x 23 cm. (9 in. x9 in.); for 
reconnaissance work and for the production of terrain sketches as well as 
for measuring spot elevations and local planimetric detail. The Stereopret 
consists of the well-known OV Stereoscope, a stereo micrometer and the 
photo carriage with parallel guide and pantograph. The smoothly 
operating parallel guide facilitates the tracing of planimetry and form 
lines. Determination of x-parallaxes with the tracing stereometer. 
Instruments for Terrestrial Photogrammetry 
Wide-angle Stereometric Camera SMK. Two cameras equipped with 
distortion-free wide-angle Topogon f = 60 mm. for plates 9 cm. x 12 cm., 
negative area covered 8 cm. x 8 cm. with synchronised compur-shutters 
and electric shutter release, mounted on standard basis of 1-20 m. with 
rugged tripod for shooting height from 1T5 m. to 2-50 m. It is specially 
suited for purposes of the traffic police. 
Phototheodolite TMK. For terrestrial photogrammetric work specially 
suitable for expeditions, alpine photogrammetry, engineering projects 
such as dam site construction, etc. Equipped with distortion-free wide- 
angle Topogon, focal length 60 mm., for plates 9 cm. x 12 cm., negative 
size 8 cm. x 10 cm., built-in sighting telescope. By means of plug pivot 
interchangeable against Zeiss Theodolite Th. 3. Target signal equipment 
and other accessories. 
Terragraph. A new plotting instrument for photographs taken with the 
wide-angle Stereometric Camera SMK and the Phototheodolite TMK. 
Convenient operation due to oblique observation and inclined drawing 
table. The design of the instrument is based on purely mechanical 
projection. 
Activities and Products 
Zeiss-Aerotopograph G.m.b.H. was founded in 1931 at Jena by a merger 
of the photogrammetric department of the world-famous Carl Zeiss-Works 
and Aerotopograph G.m.b.H., Dresden. The vast stock of experience 
and patents held by both firms in the photogrammetric field were pooled 
in the new enterprise.
