A new UV spot lamp earns its keep on day one only if the setup is written down. The steps below turn an Incure L9000™ arriving on the bench into a documented, repeatable cure station before the first production part runs.
Q: What Should Be Done Before an L9000™ Cures Its First Production Part?
A: Verify the Configuration, Fix the Standoff, Record a Radiometer Baseline, Lock the Recipe, and File the Records
Commissioning has five stages, in that order. Skipping the baseline reading is the most common gap, because without it there is nothing to compare against months later when cure quality is questioned.
Stage 1: Receiving Inspection
Start by confirming the unit matches the order. Check these items against the purchase record:
- Wavelength. Each L9000™ is factory-configured to one of 365, 375, 385, 395, or 405 nm. Confirm the label matches the wavelength your adhesive needs, since it cannot be changed on the floor.
- Configuration. L9000-BASE ships without a guide for pairing with existing tooling. L9000-CG is the Cool Guide with a 24 mm cube head, integrated fan, and 83 mm total length. L9000-SG uses a 66 mm guide, and L9000-LG extends to 118 mm.
- Guide count. Up to four independent lightguides can run from one controller. Count what arrived against what the fixture needs.
Inspect each guide tip for scratches or residue before installation, and note its serial or lot marking in the log.
Stage 2: Guide Installation and Routing
Seat each guide fully in its port, then route it to the fixture without kinks, twists, or pinch points from moving tooling. Follow the guide’s stated minimum bend radius and secure the run with clips rather than tape, so the path cannot shift between shifts.
For confined fixtures where heat transfer to the assembly is a concern, the Cool Guide’s fan-cooled head is the configuration designed for that case. For deep positions inside a fixture, the Long Guide’s 118 mm reach is the option to confirm. The trade-offs between these geometries are covered in the L9000™ lightguide and working-distance guide.
Stage 3: Setting the Fixture Standoff
Standoff is the gap between guide tip and bond line, and it sets both intensity and spot size. On the L9000™, irradiance at the focal point is 7,500 mW/cm² at 9 mm, 5,000 mW/cm² at 10 mm, 2,300 mW/cm² at 17 mm, 1,200 mW/cm² at 20 mm, and 223 mW/cm² at 30 mm. Spot diameter runs from 3 mm to 12 mm across that 9–30 mm range.
Pick the standoff from the bond footprint and required dose, then build it into hardware: a holder with a hard stop, a pinned bracket, or a machined spacer. Measure the installed gap with a gauge and record the actual value, not the drawing value.
Stage 4: Recording the Radiometer Baseline
With the guide fixed at the production standoff, measure irradiance at the bond plane using a radiometer matched to your wavelength. Record for each guide:
- The reading at 100% intensity.
- The reading at the intensity setting you plan to run.
- The ambient conditions and the date.
- The radiometer’s own identification and calibration date.
The L9000™ is calibration-free and rated at 15,000 hours with less than 20% intensity decay across that span. That rating describes the source. Your baseline describes the whole delivery path at your fixture, and it becomes the reference for every later check, including after any guide swap. Guide transmission can change over time, as explained in what causes UV light guide degradation over time.
Email Us if you would like Incure’s team to review your baseline readings against the adhesive’s dose requirement.
Stage 5: Writing the Timer and Intensity Recipe
Compute a starting exposure by dividing the adhesive’s required dose by the measured irradiance at the bond plane. Then set the controller:
- Timer: the L9000™ accepts 0.1–999.9 seconds.
- Intensity: adjustable from 10% to 100%.
- Trigger: manual, or PLC-controlled activation over RS-232 for automated cells.
Confirm the recipe with cure checks on real parts, not coupons alone. Once parts pass, record the final setting as the controlled recipe and restrict who may change it.
What the Commissioning Record Should Contain
A complete record lets anyone reproduce the station later. Keep one sheet per station that lists:
- Unit configuration, wavelength, and serial number.
- Guide identifiers and installed positions.
- Measured standoff for each guide.
- Baseline irradiance readings and the radiometer used.
- Timer, intensity, and trigger settings.
- Cure-check results from the qualification parts.
- Operator eye protection in use; Incure’s Vison™ goggles block 99% of UV and carry ANSI Z87.1 and EN166 certification.
After Day One
Set a recheck interval for irradiance at the bond plane and compare each reading to the baseline. Any guide replacement, fixture change, or standoff adjustment should trigger a fresh baseline rather than reuse of the old one.

Final Thoughts
An L9000™ that is commissioned with a fixed standoff, a recorded baseline, and a locked recipe produces the same dose on the thousandth part as on the first. Contact Our Team to plan commissioning for an Incure spot curing station.
