Abstract : An apparatus allows the testing of differently diametered optical fibers having different numerical apertures to determine their optical properties. A system of lenses and optically cooperating components permits the precise regulation of a light spot size and the adjustment of a particular numerical aperture so that equilibrium conditions at the launch end of a test fiber is created. Adjustments allow an observed variance of the spot size and numerical aperture so that the apparatus can accommodate differently sized test optic fibers. (Author)
