タ。[Claims for Utility Model Registration] 1. In an optical isolator whose basic components are a permanent magnet and an optical element, the outside of the first holder to which the optical element and the permanent magnet or only the optical element are fixed has a screw structure, A screw structure that fits with the screw structure of the holder is provided inside a second holder to which another optical element or another optical element and a permanent magnet are fixed, and the screws of the two front holders are combined to connect each holder. When the angle formed by the optical elements attached to the holder reaches a predetermined angle, the angular relationship between the two optical elements is finely adjusted by tightening a stop ring with a screw structure on the inside that has been assembled in advance to the first holder. An optical isolator characterized by a fixed structure. 2. In the optical isolator of claim 1, angle adjustment and angle between two sets of corresponding optical elements are achieved by using at least three holders with threaded structures and two or more stop rings with threaded structures inside. A two-stage optical isolator characterized by a structure that fixes.
