Splitting a UV arc lamp’s output across multiple lightguide tips is efficient when a fixture needs several cure points — but every split divides the available intensity, and some bond lines genuinely need every watt the lamp produces concentrated in one place.
The Full Lamp Output, One Tip
The Incure S20-1P is the single-pole configuration in the Incure S20™ family, channeling the platform’s full output — greater than 21 W/cm² UVA at the source — to one lightguide tip with no splitting and no intensity loss to a second or third output. Where the 2-Pole, 3-Pole, and 4-Pole configurations divide that same lamp power across multiple simultaneous cure points, the S20-1P keeps it all in one place, making it the highest per-tip irradiance configuration in the entire S20™ range.
Why Full Intensity at One Tip Matters
Higher per-tip irradiance translates directly into faster cure at a given exposure time, or the same cure completeness in less time — a meaningful difference for thicker adhesive bond lines and highly filled formulations that need more UV energy to reach full depth of cure than a thin film does. Splitting the lamp’s output across multiple poles is the right call when a fixture has several cure points to hit simultaneously; keeping it undivided is the right call when a single joint needs the fastest, most complete cure the lamp can deliver.
Broad-Spectrum Output Covers Standard Photoinitiator Chemistry
The S20-1P is powered by a 200 W mercury arc lamp delivering broad-spectrum output from 300 to 550 nm, activating essentially all standard photoinitiator systems without requiring adhesive reformulation or a separate compatibility check — a meaningful practical advantage over single-wavelength LED sources when a facility runs several different UV-curable materials through the same lamp. Output intensity is adjustable from 25% to 100%, with a programmable timer from 1 to 99 seconds. Lamp life is rated above 2,000 hours typical.
The Widest Tip Selection in the S20™ Range
Because all of the lamp’s output routes to a single lightguide, the S20-1P supports the widest range of tip diameters in the family: Ø3, Ø5, and Ø8 mm, in lengths from 0.5 to 6.2 meters. The Ø8 mm maximum-aperture tip is only available on this single-output configuration — splitting the lamp across multiple poles doesn’t leave enough power per tip to make a larger-aperture guide practical. UV protective safety goggles are included with the unit.
Operating Environment and Duty Cycle
The S20-1P operates within a rated ambient range of +10°C to +40°C and 30–75% relative humidity during operation, with a warm-up time of 1 to 2 minutes and a cooling period of 2 to 5 minutes typical before restart. Dual filtered DC fans handle cooling, with an internal over-temperature shutdown at 65°C protecting the lamp from damage during extended or high-duty-cycle use. Planning cycle timing around the warm-up and restart-cooling windows matters most on stations running frequent on/off cycling rather than continuous operation, where the cooling-before-restart interval can become a real factor in achievable throughput.
Physical Footprint and Handling
The S20-1P’s controller measures 10.6″ × 8.7″ × 4.1″ and weighs 6.0 lbs (2.7 kg) — small enough for bench-top placement without dedicated equipment mounting in most installations, though the lightguide length selection (from 0.5 to 6.2 meters) still needs to account for the distance between wherever the controller sits and where the cure point actually is. On a manual bench station, choosing a lightguide length with some slack for operator movement, rather than the shortest option that technically reaches the part, tends to reduce cable strain and extend the fibre optic’s working life.
Matching the S20-1P to Precision Dispensing and Bonding Work
High-intensity single-point cure is common in fibre optic connector assembly, precision component bonding, and single-point structural joints where fluid is dispensed and cured at one location per cycle. Pairing the S20-1P with the right dispensing hardware for the adhesive viscosity in use matters as much as lamp selection — the Incure Sniper™ precision dispensing needles line covers bore and coating selection matched to fluid characteristics. For optical-grade bonding specifically, the Incure Optik™ UV optical adhesives line documents index and viscosity data worth checking against the S20-1P’s broad-spectrum output.
Because the S20-1P delivers full lamp intensity at close working distance, Incure Vison™ UV-blocking eyewear — beyond the goggles included with the unit — is worth standardizing on across any bench station running this configuration, particularly for extended production shifts.
