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.
