FAQs
What is the Dymax 38478 four-pole liquid lightguide used for?
The 38478 is a multi-pole (four-pole) liquid-core lightguide designed to deliver UV/visible light from Dymax spot-curing lamps to adhesive, coating or sealant surfaces. Its liquid light-conducting core enhances light transmission efficiency and enables simultaneous curing at multiple points with a single source.
What are the key specs and construction details of the 38478?
This model features a 3 mm diameter tubing, 1 m length, four output poles, each delivering about 37% of the optical output. It comprises plastic tubing surrounding a light-conducting liquid core and is compatible with Dymax BlueWave spot lamps.
Which lamp systems are this lightguide compatible with?
The 38478 is compatible with Dymax BlueWave® spot lamps and other models listed in the light-guide specification suite. Proper connector type (“D” or “Wolf”) and system optic configuration must be verified.
What advantages does the liquid core lightguide bring compared to quartz fiber guides?
Liquid-core guides like this one transmit higher intensity (>35 % more in many cases) than traditional quartz-fiber guides for UVA/visible wavelengths, and offer cleaner delivery with less scattering. However, they require proper balancing and are less suited for UVB/C wavelengths.
What maintenance or usage considerations should I know?
Over time, intensity drops (for example, from ~7.4 W/cm² initial to ~3.7 W/cm² at 2000 hours for this model). Proper cleaning, avoiding sharp bends, and using the correct connector and fixture mount are essential. Use a radiometer to verify output when processes demand consistency.
