Clear and convenient
photo-interpretation
The "Old Delft" Scanning Stereo-
scopewhich hitherto was providedwith
xV/2 and x4]/2 magnifications now
offers a full range of interchangeable
magnifications from low power xV/2
to high power x9 for stereoscopic ex

found in forestry. In a few minutes the
standard eyepieces which give
x1 y2 and x4l/2 magnification can be re
placed by two different pairs of eye
pieces (see illustration) for either x2
and x6 or x3 and x9 magnification
respectively.

matter of minutes by unscrewing the standard
eyepieces and inserting the new set.
