Title: Method and apparatus for evaluation of lens-equipped optical isolator
Inventor: SUGA TETSUYA
IPC: G02B27/28
Filed: 1994-09-08
Abstract: PURPOSE: To evaluate an optical characteristic such as an aberration, a spot diameter or the like when an optical signal is passed through a lens in the opposite direction by a method wherein an external magnetic field which lowers an isolation is applied to the outside. CONSTITUTION: In an electromagnetic coil 7 in which a conductor has been wound in a spool shape, a lens equipped optical isolator for an object to be evaluated is arranged and installed in an internal space. A controller 8 to which the conductor for the coil 7 is connected controls a current which flows in the conductor, and it adjusts the intensity of a magnetic field which is generated by the coil 7. Collimating light from a semiconductor laser light source 10 is passed through the lens equipped optical isolator which has been arranged and installed inside the coil 7, and it evaluates the beam profile of a laser beam by means of a CCD camera 9. At this time, the magnetic field which is generated by the coil 7 loweres the isolation of the lens/equipped optical isolator.  Thereby, it is possible to evaluate an optical characteristic, such as an aberration, a spot diameter or the like when an optical signal in the opposite direction its transmitted so as to pass a lens in the opposite direction.
