Reflection Goniometer 302
Perfectly grown single crystals have surfaces and sharp edges which are oriented to one another according to their main crystallographic planes. Light-optical goniometers are used for determining the plane angles. In this process the angles of the plane normales are measured.
The Goniometer 302 is designed for crystal dimensions of between 0.01 and approximately 5mm. The positioning and read-out accuracies are 0.01° or mm respectively. This precision is required for the preliminary adjustment on a goniometer head if the crystal is to be investigated by structural diffractometry.
