The instrument consists of the standard Kopf rugged “U” frame assembly. Affixed to the “U” frame are two Model 961 Ultra Precise Micro Manipulator. Model 1770 Electrode Holder with corner clamp are included.
The vertical and lateral slides are mounted on a massive universal joint that is calibrated in two planes. Very close tolerances are held in production with all dovetail slides precision ground. This along with backlash-free drive screws and the sheer mass of the manipulators, assures the most accurate placement of electrodes. Screws are rendered backlash free by use of split spring-loaded nuts.
Manipulator X, Y, Z adjustment – Metric scale
80 mm travel. Calibrated dial – 10 micron resolution 1.0 mm of travel per revolution.
Angle adjustment – Fully universal joint calibrated on two planes for access from any angle. Vertical alignment pin can be removed for angled settings from 0° – 90° either side of vertical.
