ABSTRACT:
This apparatus comprises: (a) a housing; (b) a first microscope placed in said housing to observe optical fibers; (c) a first light source facing to said first microscope; (d) a second microscope placed in said housing to observe said optical fibers; (e) a second light source facing to said second microscope; (f) a third microscope placed in said housing to observe said optical fibers; and (g) a third light source facing to said third microscope. When the first light source is turned on, the first light emitted from the first light source irradiates the optical fibers. When the second light source is turned on, the second light emitted from the second light source irradiates the optical fibers when the first light source is turned on, enlarged images of the fibers are observed, and when the second light source is turned on, enlarged images of the fibers are observed with said second microscope. These fibers are observed from different directions without moving these microscopes.
