OmniCure AC4 LED Small-Area UV Curing System

OmniCure® AC4 Series of air-cooled LED UV curing systems are designed with high output LEDs and custom optics to deliver high irradiance of over 8W/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.

Features and Benefits:

Output of over 8 W/cm2: High speed curing for adhesives, coatings and inks

Custom front-end optics: Greater flexibility in the curing process via high peak irradiance available at longer working distances

Patented process for addressing individual LED modules: Even and consistent curing through excellent uniformity across the full LED area

Available in 395 nm and 365 nm: Ability to select the optimum wavelength for specific adhesives, coatings or inks and also the substrates to best suit the application

Air-cooled design: Easily integrated into any workstation with no additional venting, ozone extraction or chillers required

I/O Port for remote operation: Ability to automate for increased productivity

Highly-efficient LED modules: Costs savings from reduced power consumption compared to arc-lamp systems

Compact size: Easily integrated into any workstation

20,000 hour typical lifetime: Reduced running costs when compared to arc-lamp solutions

Narrow wavelength output of LED: Increased yields of parts due to lower temperature curing compared to arc lamp systems
