Fiberguide Industries is offering custom optical fiber drawing on its research towers on a fee-for-service basis. Preforms are available in fiber sizes from 25 to more than 2000 µm. Standard and custom preforms can be drawn, as well as fused silica, specialty glasses and other hard or high-melting materials. Rod geometries, such as square, oval and multiple canes, can also be drawn. Fibers are coated with polymers or hermetic coatings, such as silicone, acrylate and gold. Engineering and consulting services are provided.
