ABSTRACT:
For the measurement, orientation and fixation of at least one single crystal, it is the object of the invention to ensure increased accuracy in the determination of crystallographic orientation and oriented fixation regardless of the outer geometry of the single crystals, and the fixation should guarantee a highly accurate cutting also with very hard materials such as sapphire or silicon carbide. The single crystal is adjustably positioned on a revolving table for determining the crystal lattice orientation, wherein the crystal lattice orientation is determined during at least one revolution of the revolving table based on a plurality of x-ray reflections. The orientation of the crystal lattice is carried out with reference to the determined angles of the normal of the lattice plane relative to the axis (X-X) of the revolving table as reference direction before carrying out the fixation of the single crystal and the fastening on a support oriented in reference direction. By virtue of the invention, a plurality of single crystals can be oriented, fixated, stacked one on top of the other and connected to one another and subsequently connected simultaneously to a common support. Further, the invention makes it possible to monitor the orientation of every single crystal after fastening to the common support.
