Abstract

Goniometer 10 functions to orient and hold specimen 11 at any desired angle for optical or X-ray use. Specimen 11 is mounted in specimen holder 12 which in turn is seated in hemisphere 13 so that the specimen surface is positioned at the center of rotation of 13. The latter is adapted to be rotated by hand in supporting cup 14. This has an inside diameter equal to the diameter of hemisphere 13. Circles 15 are scribed on hemisphere 13 at 2 degree increments to enable reading latitudinal measurements after hemisphere 13 is rotated to the desired position and locked in place by a vacuum. This is applied to cup 14 by conduit 16. Angle measurements are made from the flat surface of cup 14 to the flat surface of hemisphere 13.
