OmniCure AC4 UV LED Small-Area Curing System

OmniCure® AC4 Series of air-cooled UV LED curing systems are designed with high output LEDs and custom optics to deliver high irradiance of over 8 W/cm2 with exceptional uniformity at long working distances. Consisting of the OmniCure AC450, AC450P, AC475, AC475P, our AC4 Series utilizes our patented process for individually addressing each LED UV module output to provide consistent results by ensuring high longitudinal uniformity over the entire 50 mm (2″) to 75 mm (3″) curing area. A uniform exposure area allows for curing of larger and/or multiple parts simultaneously enabling manufacturers to achieve highest productivity and reduced running costs.

The AC4 Series offers precise control of the UV irradiance level and time to ensure that the correct dose of UV energy at the required wavelength is provided on every exposure for a repeatable curing process. Intelligent system monitoring and control ensures system reliability meets the demands for any application.
