Five equipment families all get called “UV curing systems,” and picking the wrong one is a bigger error than picking the wrong lamp wattage. Part geometry, bond-line shape, and volume decide the family before intensity or wavelength ever enter the conversation.
Q: Which Type of UV Curing System Fits My Process?
A: Match the Family to the Shape of the Cure Zone
Use a spot system for small, discrete bond points, a flood lamp for whole-panel exposure, a chamber when stray UV must be contained and distance fixed, and a conveyor when parts arrive continuously. Light source is a second choice: LED for single-wavelength, instant-on output, or mercury arc for broadband output across several chemistries. For the general selection logic, see Incure’s benchtop UV curing systems guide; this page maps each family to real equipment.
Spot Systems: One Bond Point, One Lightguide
A spot system pipes light through a lightguide to a point a few millimeters across. Incure’s S20™ UV arc spot lamp uses a 200W mercury arc with 275–650 nm output and 1-, 2-, 3-, or 4-pole liquid lightguides, so one controller cures up to four joints per trigger. The L9000™ is the LED counterpart: factory-set to one wavelength (365, 375, 385, 395, or 405 nm), instant-on, and rated at 15,000 hours. Choose spot curing when the bond is small, the access is tight, or the fixture holds several joints that cure together.
Flood Systems: Uniform Exposure Over an Area
When the cure zone is a board, a tray, or a panel, a flood lamp avoids indexing a spot across the part. Incure’s F-Series™ covers mercury-arc flood work from the handheld F400 and F500 to the large-area F900P (16″×12″). The L-Series™ LED line runs from the 1″×1″ L11 to the 14″×14″ L1414. The trade is built in: intensity falls as area grows, from 4,300 mW/cm² on the L11 and L22 to 950 mW/cm² on the L1414.
Chambers: Containment and a Fixed Distance
A chamber turns a flood lamp into a repeatable station. Incure’s B-Series™ pairs with mercury-arc lamps and the C-Series™ with the LED flood line. Because the shelf or drawer fixes curing distance, operator-to-operator variation drops, and a door or drawer interlock shuts off lamp output when it opens. The chamber follows the lamp you chose; it is never selected first.

Conveyors: Dose Set by Belt Speed
On a continuous line, belt speed becomes the dose control. Incure’s CDM™ UV conveyor runs from 1.5 to 12.0 ft/min and accepts LED flood heads (L64, L88), focused-beam heads (M51, M62), and mercury-arc F-Series™ heads. Slowing the belt raises dose for a thick or pigmented layer without changing the lamp.
A Decision Map in Four Questions
- How many bond points, and how large? A handful of small points suggests spot; a continuous area points to flood.
- Must stray UV be contained? If yes, add a chamber or a conveyor enclosure.
- Does one adhesive dominate? One validated chemistry favors LED; several photoinitiators favor broadband arc.
- Do parts arrive in batches or in a stream? Batches suit chamber or flood stations; streams suit a conveyor.
Mixed answers are normal. A lab might run an S20™ for micro-assembly and a flood lamp in a chamber for trays, then add a conveyor when volume rises.
Where Mistakes Happen
The common error is choosing by headline intensity. A spot lamp’s peak figure applies only at its focal distance, and a flood lamp’s figure applies across a much larger area at far lower intensity, so the numbers are not interchangeable. A second error is choosing by wavelength alone: an LED unit emits a narrow band, so a mismatch with the photoinitiator cannot be corrected after purchase. Confirm both before ordering.
Sizing the Source to the Chemistry
Equipment family answers where the light goes; source answers what the material can absorb. Photoinitiators respond to specific bands, and a thick or pigmented layer generally cures through better at 385–405 nm than at 365 nm because longer wavelengths penetrate deeper. A mercury-arc system such as the S20™ sidesteps the question with broadband output, at the cost of a 1–2 minute warm-up and a replaceable bulb rated above 2,000 hours. An LED system fires instantly and holds output over a long service life, but it commits you to one band per unit.
Combining Families on One Line
Real processes often layer families instead of choosing one. A tack cure with a spot lamp can hold a part in position before a flood or conveyor pass completes the cure, and a chamber can serve as the validation station for the same chemistry that later runs inline. Because the L-Series™ lamps and CDM™ conveyor share PLC and RS-232 control, the step from bench to line does not require a new control philosophy.
Final Thoughts
UV curing systems are a family of tools, each shaped to a different cure zone. Settle on spot, flood, chamber, or conveyor first, then choose the source and verify dose at the working distance with a radiometer. Contact Our Team to walk through which configuration fits your assembly.
