  • Termination for graded index fiber
    Patent number: 4201447
    Abstract: A short length of step index fibre is placed in front of graded index fibre. Walls of the step index fibre form multiple images of its entrance face which are imaged by the graded index fibre to give a more nearly uniform illumination of the graded index fibre and thereby avoid the variable loss properties which can result from the repetitive focusing produced by point illumination or well collimated illumination.
