Notes:
1. The staining which appears on the light emitting end of the light guide is the
result of gaseous burn-off from the UV adhesive.
2. Inspect light guide optical input port of R2000 Radiometer for signs of residual
gaseous burn-off powder/dirt, transferred from the light emitting end of the light
guide, clean as stated below.
3. Never apply a dirty tissue/swab to the end of the light guide or R2000 optical
input port.
4. Never use a razor blade or any other metallic apparatus to scrape off adhesive
build up from the quartz lens on the light emitting end of the light guide. This may
cause permanent damage (scratches) to the quartz lens.
Procedure:
1. Turn off power to the UV spot curing system and let the light guide cool down for
at least 10 minutes.
2. If required, remove light guide output end from the production fixture.
3. Remove the light guide from the light guide port of the UV spot curing system.
4. Place the protective cap onto the light guide input end while cleaning output end.
5. Wipe output end of light guide with non-abrasive lint free lens tissue or optical
swab saturated with an IPA cleaning solution until the staining has disappeared.
6. For excessive adhesive build up on the light emitting end lightly scrape the
adhesive build up with a wooden stick such as tongue depressor/popsicle stick.
Take care not to damage the quartz lens.
7. Re-install the light guide as per the instructions located in the relevant UV spot
curing manual/user guide.
8. For cleaning R2000 optical input port; wipe surfaces with non-abrasive lint free
lens tissue or optical swab saturated with an IPA cleaning solution until the
staining has disappeared. Care is to be taken to avoid puddling/over saturation of
input port.
