Abstract
PURPOSE: To grow a single crystal with no angle error by adjusting the inclination of a seed crystal so that a parallel beam reflected at a mirror part formed on a side of the seed crystal impinges on a predetermined position of a scrren indicator, thereby easily adjusting the perpendicularity of the seed crystal.
CONSTITUTION: Part or more of a seed crystal 1 face corresponding to the principal face of a plate crystal to be grown is first mirror-polished in a proper crystal orientation. Crystal 1 is fixed into holder 2, and parallel beam 6 is allowed to impinge on mirror part 5. Inclination θ of crystal 1 is adjusted so that the beam reflected at part 5 impinges on the "+" mark position of screen 8 which position is formed when part 5 becomes perpendicular. Crystal 1 adjusted to the proper perpendicular position is then pulled in the Y axis direction together with holder 2 to obtain a LiNbO3 plate crystal or the like with a predetermined crystal face properly held.
