Filed: 1990-06-04
Abstract: PURPOSE:To reduce the diameter of a light guide tube by forming a metallic protection film for reflecting light and heat rays directed to an adhesive face formed on the light incident side end face of a light guide on the adhesive face, and highly accurately making light incident upon the light guide without burning the end face. CONSTITUTION:An optical fiber 12 is arranged in a fitting 13, a gap part in the fitting is filled with adhesive 14, the adhesive 14 is cured, and then the light guide end face 10a is ground. In such a case, a cratering is formed in the end face 14a of adhesive 14 with low hardness in accordance with the difference of hardness between the fiber 12 and the adhesive 14. Then, a metal such as Au, Al and Ni is evaporated on the end face 10a to form a metallic film on the surfaces of the end faces of the fibers 12 and the end faces 14a of the adhesives 14. Since the end faces 12a are projected from the end faces 14a, only the metallic film on the end faces 12a is removed by grinding and the metallic protection film 15 is formed only on the end face 14a. Since light and heat rays directed to the end face 14a is reflected by the film 15, the burning of the adhesives 14 can be prevented, and the diameter of the light guide tube 10 can be reduced without reducing incident efficiency.
