STICKING METHOD OF OPTICAL PARTS, AND FIBERSCOPE

Title:

STICKING METHOD OF OPTICAL PARTS, AND FIBERSCOPE

Document Type and Number:

Japanese Patent JP2005043449

Kind Code:

A

Abstract:

To provide a method for sticking optical parts which improves durability to a change in temperature as a result of preventing an adhesive from separating which causes an air gap and a splice part.

At a temperature To (°C), a joining part is stuck by preparing an elastic resin 19 part between joining faces of optical parts 11 and 13. Since the sleeve 15 is thermally expanded when it is used at a temperature T1 (°C) higher than the temperature To (°C), this joining part generates tension on the joining faces of the optical parts 11 and 13, and the distance between the joining faces increases, however, the elastic resin stretches by the portion correspondingly.
