Curing inks, coatings, and adhesives
TheOmniCure® AC275 and AC2110 air-cooled UV LED curing systems combine compact size with state-of-the-art collimation optics for high irradiance and excellent uniformity. Multiple UV LED heads can be connected together while maintaining optical homogeneity between each system. The flexibility to achieve larger curing zones in various customizable lengths allows manufacturers to increase throughput without compromising performance.
Standard AC2 systems have a significantly reduced beam divergence angle compared to typical LED systems, making them ideal for printing applications where they help prevent light reflection back onto the print heads. All AC2 products come with a flat exit window that allows for easy cleaning and replacement. The infinitely variable adjustment of the radiation power enables a wide range of applications for the new AC2 series.
