Microwave UV Curing Systems for Optical Fibers

Fusion UV modular six- or ten-inch microwave-powered UV curing systems enable flexibility for configuring lamps on draw towers, coloring lines, coating systems, and wire or cable marking lines. A unique, patented secondary reflector in these Fusion UV curing systems collects UV energy and delivers it uniformly around the target. Combined with small-diameter, high-radiance electrodeless bulbs, the high-efficiency reflector produces the highest UV irradiance per watt of power of any UV lamp curing system. The modular design facilitates easy maintenance and replacement as well as control flexibility. Learn more about these solutions.

Can microwave UV curing systems be customized to meet unique project requirements?

From bulb spectral output to power level, cooling configurations, and nitrogen-purged enclosures, each component can be specified to optimize your curing process.

Whether your focus is throughput, footprint, or integration with existing fiber draw systems, our team collaborates closely with you to deliver a UV curing optical fiber solution that fits your performance, space, and scalability requirements.

How do microwave UV curing systems for optical fibers work, and what are they used for?

Our microwave UV curing systems operate using electrodeless bulbs powered by magnetrons housed in 6- or 10-inch irradiator modules. These electrodeless bulbs emit high-intensity ultraviolet light, focused using a unique full elliptical reflector design. This setup maximizes energy transfer to create a highly concentrated UV exposure zone around the optical fiber or wire substrate.

The Fusion UV DRF Series systems, including the F6 and F10T models, are widely used in UV curing photoresponsive optical fiber coatings, coloring inks, and ribbon matrix polymers. The Fusion UV DRC Series, featuring the C6 and C10 systems, targets wire and cable marking applications, particularly high-speed inkjet markings, ensuring deep, fast, and uniform curing.
