is heated and the fibers are drawn at a specific drawing pressure and rate so that the bundle is elongated and the diameter of the fibers is reduced to achieve a predetermined diameter in a particular embodiment each of the individual fibers of the bundle 370 is approximately 6 microns in diameter the preferred diameter of individual fiber rods in the bundle 370 is in the range from approximately 4 microns to about 10 microns additionally the fibers in the bundle 370 can be made from any suitable material including glass or plastic the diameter of the fiber optic bundle 370 is in the range from about 200 microns to 600 microns preferably from about 300 microns to 500 microns for descriptive purposes in this application the term u201c rods u201d is used to define optic fibers of the type referred to herein for example flexible optic fibers further referring now to fig5 a cross section of an embodiment of the nozzle 30 illustrated in fig4 is shown a plurality of illumination transmitting fiber optic rods or fibers 380 is axially disposed in the nozzle 30 there are typically about 6 000 fiber optic rods in the fiber optic bundle in a particular embodiment the rods 380 are positioned within the second lumen 330 and extend from the second opening 350 of the nozzle 30 to the light source 57 shown in fig1 2 in one embodiment of the invention the nominal diameter of the bundle 370 is 375 microns in another embodiment the rods 380 having diameters ranging from 0 003 to 0 008 inch are bundled in a plurality of bundles 370 having diameters ranging from 0 020.
