OLD DELFT SCANNING STEREOSCOPE - ODSS III 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 amination of minute details, e.g. as are 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. Advantages Economy Greater versatility in one stereoscope, thus per mitting a variety of applications. Compactness All possibilities in only one instrument; no acces sories other than two sets of eyepieces for all magnifications. Ease of operation Changing of magnifications can be effected in a matter of minutes by unscrewing the standard eyepieces and inserting the new set. N.V.
