PRODUCTION METHOD OF FIBERSCOPE WITH THIN DIAMETER

摘要

PROBLEM TO BE SOLVED: To provide a production method of a fiberscope with a thin diameter which can prevent the occurrence of a damage such as peeling or the like of a splicing surface between an optical component such as an objective lens or the like and an image fiber. SOLUTION: A tube 2 wherein a pointed head section of a light guiding fiber 3a and a pointed head section of the image fiber 4a are inserted is heated up to a cure temperature of an adhesive agent 15 within a period of maintaining a fluidity of the adhesive agent 15, and the pointed head section of a light guiding fiber 3a and the pointed head section of the image fiber 4a are fixed in the tube 2 by curing of the adhesive agent 15 while the tube 2 is expanded along an axial direction by the above heating.
