  • SYSTEM, METHOD & DEVICE FOR UV CURING
    Publication number: 20130228707
    Abstract: A system, method and devices for providing improved methods to harden UV-curable coating materials when those coating materials are applied over optical fibers or other optical targets during the manufacturing process is provided. The technology disclosed herein uses LEDs (or low power light bulbs) to create UV power, which is focused with high intensity on the surface of a coated fiber. This is done simultaneously from multiple angles to fully cover the target product over 360 degrees of surface and is then repeated a number of times along the product path to ensure sufficient degree of curing.
