CORNER CUBE REFLECTOR AND MANUFACTURING METHOD OF THE SAME, AND MIRROR HAVING REFRIGERANT-PASSING SPACE AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a corner cube reflector which achieves the high smoothness at corner parts of the corner cube reflector.SOLUTION: A manufacturing method of a corner cube reflector includes: a step of producing a mold of the concave corner cube reflector whose three planes have a 90-degree angle to each other; a step of electroplating a surface of the mold of the corner cube reflector with metal; a step of stoping the electroplating when a thickness of the metal with which the surface of the mold of the corner cube reflector is plated reaches a predetermined value; and a step of melting the mold of the corner cube reflector.
