Configure & Order Your Lightguide
LED fiber lightguides for the Incure L9000™ UV LED spot lamp and liquid
light guides for mercury arc, xenon, and halogen UV spot lamp systems.
Precision Spot Curing Across Industries
Lightguides deliver concentrated UV energy to exact curing locations —
essential for bonding, sealing, and coating applications where flood exposure is not suitable.
Frequently Asked Questions
Common questions about Incure UV lightguides and liquid light guides.
-
LED fiber lightguides (Cool Guide, Short Guide, Long Guide) are solid fiber optic assemblies engineered for the Incure L9000™ UV LED spot lamp. They transmit UV from the LED controller to the curing point and carry a 15,000-hour rated life. Liquid light guides use a liquid-filled flexible tube optimized for high UV transmission efficiency across a broad spectrum and are designed for traditional mercury arc, xenon, or tungsten halogen UV spot lamp systems.
-
The Cool Guide (24 mm cube head, 83 mm total length), Short Guide (66 mm), and Long Guide (118 mm) are the three lightguide assemblies designed for the Incure L9000™. Each is wavelength-configured at the factory to 365, 375, 385, 395, or 405 nm. The L9000™ supports up to four simultaneous lightguides from a single controller unit.
-
Select the wavelength that matches the peak absorption specification of your UV-cure adhesive or coating. Most UV acrylate and epoxy adhesives specify 365 nm or 385/395 nm. UV cyanoacrylates typically cure at 365–385 nm. Silicone and some specialty adhesives may specify 405 nm. Contact Incure at support@uv-incure.com with your adhesive datasheet if you need guidance.
-
The Incure L9000™ controller supports up to four independent lightguides operating simultaneously from a single unit. Multi-guide configurations are useful for parallel curing of multiple bond sites in one cycle, or for simultaneous curing across multiple fixtures on a production line.
-
Liquid light guides typically provide 1,000–3,000 operating hours under normal industrial UV intensity. They transmit up to 5 W UV radiation at wavelengths down to 300 nm and operate reliably within −5°C to +35°C. Service life varies with UV intensity, flexing frequency, and handling. Replace when transmission loss becomes significant or visible darkening of the liquid core is observed.
-
Liquid light guides are designed for traditional UV spot lamp systems using mercury arc, xenon, or tungsten halogen sources. For the Incure L9000™ UV LED spot lamp, use the dedicated LED fiber lightguides (Cool Guide, Short Guide, or Long Guide) which are engineered for the L9000™ connector interface and LED output characteristics.
