Claims

[Claims for Utility Model Registration] An optical fiber guide 2 having a convex curved surface 1 and a concave curved surface 3
The optical fiber 6 is sandwiched between the convex curved surface 1 and the concave curved surface 3, and the optical fiber 6 is bent beyond the critical angle for total reflection. The leakage light from the optical fiber 6 is detected by the photodetector 5.
In the optical fiber core comparison detector for detection, there are a connecting plate 9 attached to the end 8 of the optical fiber guide 2, a knob 10 for sliding the connecting plate 9, and a connecting plate 9 placed on the side of the optical fiber holder 4. When the knob 10 is pushed toward the optical fiber guide 2 side, the convex curved surface 1 and the concave curved surface 3 open, and when the knob 10 is released, the convex curved surface 1 moves to the concave curved surface 3 side and makes contact. A detector for comparing optical fiber cores.
