MULTIPLE CAPILLARY TUBE

摘要

PROBLEM TO BE SOLVED: To provide a multiple capillary tube which can accurately array and hold plural optical fibers by inserting them altogether and easily position and fix them for the other optical system. SOLUTION: This multiple capillary tube 2 is sectioned nearly square and constituted by fixing an external tube 4 which has necessary thickness to the outer periphery of a glass internal tube 3 having insertion holes 3a where two optical fibers 5 and 6 are inserted at t time and arrayed by using an adhesive 8, and the external diameter of the multiple capillary tube 2 is equal to the diameter of a columnar lens.
