When a cure schedule’s bottleneck is dwell time rather than total dose, the fix isn’t more exposure — it’s more irradiance per second, and the F500x2AC sits at the top of what the CDM™ arc lineup can deliver on that spec.
590 mW/cm² — the Highest Single-Assembly Arc Intensity Available
The Incure CDM™ / CDM™ Compact + F500x2AC pairs either belt platform with a single F500x2AC lamp assembly — one UVA lamp head and one UVC lamp head, shipped as one unit — delivering 590 mW/cm² at 365 nm, 20% more than the F400x2AC’s 490 mW/cm² and 69% more than the F200x2AC’s 350 mW/cm². For fast-response photoinitiator systems, processes with tight cycle-time budgets where dwell time is the constraint, or formulations with high minimum-irradiance thresholds, the F500x2AC is the ceiling configuration in the fleet.
Full Broadband Compatibility at That Intensity
Like every x2AC single-assembly configuration on the CDM™ fleet, the F500x2AC delivers simultaneous UVA and UVC exposure from one lamp assembly in a single belt pass — no secondary lamp source or second conveyor stage required for adhesives specifying broadband arc-lamp cure. It’s the same broadband process compatibility as the F100x2AC, F200x2AC, and F400x2AC, just delivered at the highest per-head intensity available on this platform. If a process is qualified under UVA-only exposure, the F500x2A (two UVA heads, no UVC) is the correct alternative instead.
A Trade-Off Worth Understanding Before Ordering
The F500’s aperture is shorter in the belt-travel direction than the F400’s, which means total energy per pass at a given belt speed is actually lower than the F400x2AC despite the higher peak irradiance — 1,480 mJ/cm² versus 2,630 mJ/cm² UVA at 6 ft/min. When total dose per pass is the primary process requirement, the F400x2AC delivers more of it; when peak irradiance is the deciding factor, the F500x2AC is the correct choice even at a lower total-dose number.
Confirming which variable — peak irradiance or total dose — actually governs a given adhesive’s cure is worth doing before specifying the highest-intensity option by default. Email Us with your process requirements and Incure can help confirm.
A simple way to test which variable actually matters: if a formulation still cures reliably when belt speed is slowed to increase total exposure time at a lower peak intensity, total dose is the governing factor and the F400x2AC’s higher per-pass energy is the more efficient configuration. If cure quality drops sharply below a specific peak irradiance no matter how much extra dwell time is allowed, the F500x2AC’s higher peak output is what the formulation actually needs.
Available on Both Belt Platforms
The F500x2AC lamp assembly runs on both the standard CDM™ (polypropylene belt) and CDM™ Compact (stainless-steel wire belt), sharing the same 3.0–6.5 inch curing height range on either chassis — what changes at order is the conveyor chassis and part number prefix. The UVA and UVC lamp heads replace as a single assembly at the 1,000-hour threshold; a mounting stand is not available for F500 configurations. As with the rest of the arc fleet, belt speed adjustment is the only process control on this configuration — see the Incure M-Series™ UV Focused Beam Curing Systems line for a controllable LED alternative on the same chassis.
This is the top-tier arc configuration in the Incure CDM™ UV Conveyor lineup — getting the highest available intensity isn’t the same as getting the right configuration for a given formulation.
A Configuration for a Specific Kind of Bottleneck
The F500x2AC makes the most sense on lines where dwell time under the lamp, not total available UV energy, is the actual constraint — a cure schedule that’s throughput-limited by how fast a part can pass through the curing zone rather than by how much total dose the adhesive needs. On a process where dwell time isn’t the bottleneck, the F400x2AC’s higher total dose per pass is generally the more useful spec to optimize for instead.
Uniformity at the Top of the Range
Dynamic uniformity at 2.0 inches for the F500x2AC is 0.81, with static uniformity at 0.74 — very slightly below the 0.82/0.75 typical of the F100/F200/F400 tiers, a function of the F500’s more concentrated aperture rather than a quality difference. At the intensities this configuration delivers, that small uniformity difference is rarely the deciding factor in a configuration choice; the real trade-off remains peak irradiance versus total dose per pass against the F400x2AC.
Reading Photoinitiator Data Correctly Before Choosing
The F500x2AC is easy to over-specify if the selection process stops at “highest available intensity.” Adhesive technical data sheets typically document cure requirements as either a minimum irradiance threshold, a total dose target, or both — and which one governs a given formulation determines whether the F500x2AC’s peak intensity or the F400x2AC’s higher total dose per pass is the better fit. Confirming which requirement actually applies before ordering avoids specifying the ceiling configuration for a process that would have cured just as reliably, and more cost-effectively, on the F400x2AC.
