An adapter-type optical isolator (1) has split sleeve (7) within housings (A) and (B). Polarization-independent optical isolator is of such a structure that optical isolator device (3) which is an integral assembly of a Faraday rotator (34) and a birefringent crystal element (31, 32) is provided within hollow cylindrical magnet (4). Beam changing elements (5a, 5b) are in the form of optical coupling lenses or core-flared fibers. The adapter-type optical isolator (1) has the polarization-independent optical isolator and beam changing elements (5a, 5b) fitted snugly within the bore of split sleeve (7) in such a way that the polarization-independent optical isolator is held between beam changing elements (5a, 5b). An optical connector using the adapter-type optical isolator (1) is simple in construction, permits simple assembly and adjustments, is small, allows for easy optical adjustments on individual optical parts, features high operational stability and can be incorporated into a wide variety of measuring instruments and communication equipment. <IMAGE> |
