What is the maximum bond count achievable with one lamp and the LLG-4P-3?

The Incure LLG-4P-3 delivers UV to four independent bond points in a single trigger cycle — the highest bond count available from a single lamp controller in the liquid light guide range. On a four-joint assembly, one trigger event replaces four sequential single-pole exposures, three repositioning steps, and three waiting periods. No additional lamp controllers or light sources are required.

What cable lengths are available for the LLG-4P-3?

The Incure LLG-4P-3 is available in three cable lengths: 1,000 mm, 1,500 mm, and 2,000 mm. The 2,000 mm option is the longest available for any multi-pole LLG variant, accommodating four-station fixtures with wider separation between the bond positions and the lamp controller.

How does the LLG-4P-3 compare to using the L9000™ with four lightguides?

The Incure LLG-4P-3 works with existing mercury arc, xenon, and halogen spot lamp controllers — it requires no new lamp investment if the line already has an arc spot curing system. The Incure L9000™ with four lightguides is the preferred solution for UV LED spot curing, offering factory-configured wavelengths (365–405 nm), up to 7,500 mW/cm² per guide, and the longer cable lengths (2,000–5,000 mm) suited to larger fixture envelopes.

Does the LLG-4P-3 require a special lamp controller?

No. The Incure LLG-4P-3 connects to any mercury arc, xenon, or halogen spot curing lamp with a compatible input port. The four-pole split is built into the guide — the lamp controller treats it as a standard single lightguide connection. No firmware changes, output channel configuration, or additional hardware is required at the controller.

What is the cure spot size at each output pole of the LLG-4P-3?

Each output pole of the Incure LLG-4P-3 delivers a 3 mm core UV spot. The Ø3mm spot limits the irradiated zone at each bond point, preventing UV exposure of adjacent components in dense four-joint assemblies. If a wider spot per bond face is required, contact Incure to discuss alternative configurations.

Quad-Pole Liquid Light Guide — Incure LLG-4P-3

Name: Incure LLG-4P-3 Quad-Pole Liquid Light Guide
Brand: Incure

Incure LLG-4P-3 is the highest bond-point count in the LLG range — four cure points in one machine cycle from a single lamp controller, where covering four joints with single-pole guides would require four separate lamps. Each of its four output poles carries a 3 mm core delivering UV from 300 nm through the visible range, in 1,000 mm, 1,500 mm, and 2,000 mm cable lengths. Compatible with mercury arc, xenon, and halogen spot curing lamps.

Four Cure Points in One Machine Cycle — Maximum Bond Count Without Lamp Multiplication

The LLG-4P-3 cures four bond joints simultaneously from a single trigger event, using one lamp controller. Where four sequential single-pole exposures require four activations and three repositioning steps, the quad-pole guide completes the same work in a single cycle. No additional lamp controllers, no additional light sources, and no additional trigger infrastructure are required. Adding more lamps to reach four bonds is the expensive path; using one lamp with the LLG-4P-3 is the efficient one.

All Four Bonds Receive Identical UV Dose in One Exposure — No Within-Part Variation

Sequential single-pole curing on a four-joint assembly accumulates dose variation across all four bonds — the last bond cured may differ from the first due to lamp temperature, shutter timing, or operator consistency over the sequence. The LLG-4P-3 eliminates this source of variation entirely: all four bonds are exposed at the same moment, from the same lamp output state, for the same duration. The four joints are, by definition, dose-matched — a process control advantage that has direct value in validation documentation for medical device and precision optical assembly lines.

Highest Bond-Point Count in the LLG Range — Four 3 mm Spots From One Source

At four output poles, the LLG-4P-3 reaches the maximum simultaneous bond count achievable with a single liquid light guide connected to one lamp. Each pole delivers a 3 mm core UV spot to its individual bond face, keeping irradiation confined to the bond zone in dense multi-joint assemblies. The 2,000 mm maximum cable length — the longest available for any multi-pole LLG — accommodates four-station fixtures where bond points are spread across a larger fixture envelope.
