A flood lamp curing a narrow adhesive bead on a densely packed board doesn’t just cure the bead — it irradiates everything around it too, which is exactly the problem on an assembly where a heat- or UV-sensitive component sits millimeters from the bondline. Incure’s M-Series™ solves that with a narrow rectangular beam instead of a broad flood field, sized to the bondline rather than the whole part.
Five Models, One Design Principle
M51 (5″×1″) and M121 (12″×1″) are the narrow-format models, built for linear bondlines like gaskets and seals where the cure zone genuinely is a thin line rather than a wide band. M62 (6″×2″), M122 (12″×2″), and M152 (15″×2″) double the beam width for wider zones, multi-row dispensing patterns, or applications where a small amount of lateral placement tolerance is needed. The choice between the two widths comes down to how tightly the actual bondline is confined — a 1-inch beam wasted on a 2-inch dispensing pattern leaves part of the bead under-cured, while a 2-inch beam on a true hairline bond irradiates adjacent area that didn’t need exposure.
Peak Intensity Varies by Wavelength, Not Just by Model
M51 leads the line at 6,150 mW/cm² at 365 nm, measured 2 inches from the lamp face — but that figure drops to 5,100 mW/cm² on the same unit at 385, 395, or 405 nm. The pattern holds across the range: every M-Series™ model reads highest at 365 nm and measurably lower at the longer wavelengths, so a spec sheet quoting one intensity number without stating the wavelength it was measured at is quoting an incomplete figure. Confirming which wavelength an adhesive’s photoinitiator actually absorbs at is the first step in reading M-Series™ intensity data correctly, not an afterthought once the unit is running under spec.
One Wavelength Per Unit, Selected at Order Time
Each M-Series™ model is available in 365, 385, 395, or 405 nm, but — the same configuration pattern as Incure’s L9000™ spot lamp and L-Series™ flood lamp lines — the wavelength is fixed at the factory to whatever’s specified on the order, not switchable afterward. That makes matching the adhesive’s absorption peak to the ordered wavelength a pre-purchase decision rather than a floor adjustment.
No Chamber, By Design
Unlike Incure’s B/C-Series™ cure chambers, the M-Series™ is explicitly not chamber-compatible — every model in the line is built as a standalone curing head for open-fixture tooling, not an enclosed batch process. That’s a deliberate design split, not a missing accessory: a focused beam curing a specific bondline on an in-process fixture needs direct optical access to that fixture, which an enclosure would block. A process that genuinely needs enclosed batch curing calls for the B/C-Series™ paired with a flood lamp instead.

Recommended Working Distance and Uniformity
Incure specifies a 1- to 3-inch working distance for the full M-Series™ line, with peak intensity figures measured at 2 inches — closer increases intensity but narrows uniformity, farther broadens the beam footprint slightly while reducing intensity. Static uniformity across the beam is rated at 0.78 at 2 inches and 0.62 at 3 inches; dynamic uniformity (accounting for part or lamp motion during cure, relevant on a conveyor-integrated setup) improves to 0.88 and 0.82 at the same distances. Every model runs on universal 100–240V auto-ranging power and forced-air cooling, with LED life rated past 20,000 hours — mercury-free solid-state output that holds steady across that service life instead of decaying the way a mercury-arc bulb does over its shorter rated life.
Where the M-Series™ Fits
Electronics assembly work — PCB component bonding, underfill sealing, and FPC connector potting — is a direct fit for the narrow-beam models, where targeting the exact cure zone matters more on a densely populated board than it does on an open panel that a flood lamp would cure just as effectively. Optical component work — lens bonding, prism assembly, and fiber-optic curing — depends on the same tight beam control to avoid stray UV scatter degrading alignment or optical clarity, a pairing worth checking against Incure’s Optik™ UV optical adhesive grade guide when lamp and adhesive are specified together. Coating and encapsulant cure on complex geometries or recessed features benefits from beam targeting reaching zones a flood lamp would cure unevenly. On production lines, foot-switch, PLC, and RS232 signal inputs let the M-Series™ trigger from upstream dispensing or conveyor equipment the same way Incure’s CDM™ UV conveyor does, so a beam-cure station and a conveyor-cure station on the same line share one control architecture. In lab settings, the timer and continuous operating modes support repeatable adhesive qualification and cure-schedule development ahead of a production rollout.
