A spot lamp that delivers rated intensity on a data sheet can still under-cure in production if the lightguide can’t physically reach the bond line at the distance that intensity was measured at — irradiance on this class of lamp falls off fast with working distance, and a fixture that holds the guide even a few millimeters too far back changes the dose more than most operators expect. Incure’s L9000™ addresses that with lightguide geometry as a selection variable, not an afterthought.
One Controller, Three Lightguide Geometries
The L9000™ ships as a base controller (L9000-BASE, for pairing with existing lightguide tooling) or pre-paired with one of three lightguide configurations. The Cool Guide (L9000-CG) uses a compact 24 mm cube head with an integrated cooling fan and 83 mm total guide length, built for tight, confined fixture geometries where minimizing heat transfer to a thermally sensitive assembly matters as much as reaching the bond line. The Short Guide (L9000-SG) runs a 66 mm fiber optic lightguide suited to standard bench-top curing and semi-automated dispensing lines. The Long Guide (L9000-LG) extends to 118 mm, built for deep-reach positions inside complex assembly fixtures that the shorter guides can’t physically access. All three support up to four independent lightguides running simultaneously from a single controller, so multi-point curing on one assembly doesn’t require a second unit.
Irradiance Falls Off Fast With Working Distance
At a 9 mm focal point, peak UVA irradiance reaches 7,500 mW/cm² at 365 nm — the number most often quoted for the L9000™. Move the guide back to 10 mm and irradiance drops to 5,000 mW/cm²; at 17 mm it’s 2,300 mW/cm²; by 20 mm it’s down to 1,200 mW/cm², and at 30 mm it’s fallen to 223 mW/cm², roughly 3% of the peak figure. That steep falloff makes focal-point control part of the actual cure specification, not just a mounting detail — a fixture designed around the 9 mm figure but built with a 15 mm working clearance will under-dose the bond line even though the lamp is functioning exactly as rated. Spot diameter ranges from 3 mm to 12 mm across the 9–30 mm focal range, so working distance also sets how tightly the cure zone can be confined on a small or densely packed assembly.
One Wavelength Per Unit, Five to Choose From
The L9000™ is available in five wavelength options — 365, 375, 385, 395, and 405 nm — but each unit is factory-configured to a single wavelength rather than switchable after purchase. Selecting the option that matches the adhesive’s peak absorption spectrum has to happen before the order is placed, not adjusted on the floor later, which makes confirming the adhesive’s cure wavelength the first step in specifying an L9000™ rather than an afterthought once the unit arrives.
Email Us with your fixture’s working distance, required spot size, and adhesive wavelength, and Incure’s engineers can confirm which L9000™ lightguide and wavelength configuration actually reaches the bond line at the dose you need.
No Warm-Up, No Calibration
The L9000™ fires at full intensity from the first trigger, with no warm-up or cool-down cycle — a direct contrast to Incure’s mercury-arc S20™ spot lamp, which needs 1–2 minutes to reach full output. The L9000™ is also calibration-free throughout its rated life: unlike mercury-arc systems that need periodic recalibration and factory returns, the LED module simply gets replaced at end of life — rated at 15,000 hours, roughly 1,875 working days at 8 hours a day, with less than 20% intensity decay across that entire span. That maintenance-cost gap between LED and mercury-arc spot curing is covered in more depth in Incure’s breakdown of why UV LED has lower operating costs than mercury spot systems.
Multi-Point Curing and Automation
Running up to four lightguides from one controller means a single L9000™ can cure four bond points on one fixture or feed four separate stations without adding controllers, and the RS-232 port supports PLC-controlled activation for lines where the cure trigger needs to fire on a signal rather than a manual switch. That automation path pairs naturally with high-throughput inline curing on conveyor systems and robotic dispensing cells — the same PLC/RS-232 integration logic used on Incure’s CDM™ UV conveyor, so a facility running both isn’t managing two different control philosophies on the same line.
Where the L9000™ Fits
PCB conformal coating cure, SMD component bonding, underfill sealing, and FPC connector assembly are common fits on automated production lines, where the four-lightguide capability curing several points per cycle keeps pace with panel throughput. Precision optics work — lens bonding, fiber optic ferrule assembly, and optical alignment — depends on the narrow spot delivery and exact wavelength match the L9000™ provides, a pairing worth checking against Incure’s Optik™ UV optical adhesive grade guide when the lamp and adhesive are being specified together. Automotive electronics assembly — ECU potting, sensor connector sealing, ADAS camera bonding, and under-bonnet electronics — draws on the thermal and vibration resistance of LED-cured bonds in an environment where a warm-up delay would slow a start-stop line. In lab settings, the programmable 0.1–999.9 second timer and 10–100% adjustable intensity make the L9000™ a repeatable tool for cure-schedule development ahead of a production rollout.
