The present invention is a fiber optic waveguide adapted for focusing a beam
of light at an obtuse angle to the optical axis. A focusing end of the fiber optic
is polished at an angle such that the surface normal does not coincide with the
optical axis, which is defined by the path of the beam of light through the fiber
optic waveguide. The angle is necessarily greater than 0 degrees and less
than 90 degrees. The present invention further includes a focusing lens coupled
to the outside of the fiber optic waveguide at its focusing end. The focusing lens
may be a ball lens, and it is attached to the exterior of the cladding layer by
an adhesive material.
