Diagnostic apparatus and method for use in the alignment of one or more laser means onto a fiber optics interface
This patent describes a diagnostic apparatus for use in the alignment of one or more beams onto a fiber optics interface. The diagnostic apparatus comprises: monitor means; lens assembly means for imaging one or more of laser beams passing through an aperture onto the fiber optics interface. The assembly means is slightly offset in an optical orientation from its center line optical axis. The lens assembly means includes at least one lens where the one lens includes reflection means on the rear surface of one lens such that when a minor scattering of laser beams are reflected from the interface back to the lens assembly means, the reflection means on one lens reflects, images and directs the scattered light toward the monitor means; the monitor means is optically oriented to permit monitoring of reflected light for indirect observation of the alignment of focused laser beams onto the fiber optics interface.
