Single Strand Bundle Fiber Optic Light Guides are generally used as supplemental lighting for hard to reach areas wherein the built-in illumination is too weak in intensity as in borescopes viewing a distant wall or spotlight affects to a distinct area.
FOI - 5
A single strand 72" long light guide with some highly unusual characteristics. It is ultra flexible but the .400" diameter Fiber Bundles are protected by an inner spring with outside PVC covering. Experience has proven this is as strong as metallic sheathing used for the FOI-2, FOI-3 and FOI-4. The glass fibers used in this unit are ultra high transmission light guides that carry 40% - 50% more light than ordinary glass fibers of the same diameter. Used with the FOI-150 Watt Halogen Illuminator or FOI-250 Watt Halogen Illuminator.
