LIGHTGUIDES

Lightguides transmit UV and visible light from a source mounted

inside of a spot-curing unit to the curing area. There are several

factors to consider when choosing a lightguide.

Length – Lightguides are commonly one meter long although

other lengths are available.

Diameter – Single-pole lightguides are available with 3-mm,

5-mm, or 8-mm inside diameters. Although the 5-mm lightguide

will register a higher intensity, the 8-mm lightguide provides more

curing power (intensity x area) because a larger lightguide

opening captures more of the light emitted from the bulb. Each

pole of a multi-pole lightguide has an inside diameter of 3 mm.

Multiple Poles – Light emitting from a spot lamp can be

channeled through a single lightguide (single pole) or split

between multiple lightguides (multiple poles). Each pole of a

multi-pole lightguide emits equal intensity (typically  10% for

liquid-filled lightguides) and all share a common shutter. Both

liquid-filled and quartz-fiber multi-pole lightguides are available

from Dymax.

Connection – There are basically two types of connectors used in

the spot lamp industry, “Wolf” and “D” connectors. Dymax

provides lightguides with both connector types, although “D”

connectors are an industry standard and compatible with current

Dymax lamp designs (older Dymax designs utilized “Wolf”

connectors).

Curing Area/Intensity vs. Distance – The UV and visible light

emitted from a lightguide diverges. As a result, intensity decreases

and curing area increases with distance from the end of the light

guide. The chart below describes this relationship clearly for the

5-mm liquid lightguide.
