Cure small areas of adhesives, coatings, and paints
Manufactured with a unique combination of high-performance LEDs and customizable optics, the air-cooled OmniCure® AC450 and AC475 UV LED lamp systemsoffer high irradiance (>8W/cm2) with flexible operating distances, enabling manufacturers to achieve excellent productivity at low operating costs.
Using Excelitas' patented processes for addressing individual UV LED module power, the AC450 and AC475 LED curing systems deliver consistent results by providing high longitudinal uniformity across the entire curing range from 50 mm to 75 mm. A uniform exposure area allows larger and/or multiple parts to be cured simultaneously. To increase throughput, it is also possible to convert a static curing process into one where parts are cured while in motion.
