Abstract
PURPOSE: To facilitate making of a small size corner reflecting miror of reflecting faces of highly accurate intersecting angles by covering the etch bit surface formed in single crystal through etching treatment with a high reflactance material.
CONSTITUTION: When a single crystal such as of NaCl or other is etched, the etch bits of high intersecting angles of specified high accuracy formed by, e.g., orthogonal crystal faces A..., B..., C... whose sizes are controlled by the intrinsic shape determined by crystal face structre and etching faces according to the temperature of etching solution and etching time are formed. If these etch bit faces are covered through vapor deposition of Al or other of high reflectance, then the small size corner reflecting mirror of reflecting faces of highly accurate intersecting angles may be made.
