quote a variety of custom guides for special purposes. These include special models
optimized for high transmission in the UV “B” and UV “C” range (230 to 390 nm). Contact
AUV/LESCO factory for price and delivery of special products.
AUV/LESCO’s precision-built LF lightguides are high quality optical instruments, but their
performance will naturally degrade with time. If cared for properly and under normal
operating conditions, the user can expect anywhere from perhaps 1 to 2 years of use
from a LF lightguide. However, normal degradation will be greatly accelerated with
aggressive radiation and/or extreme heat levels. For a given dosage, it is well
established that high intensity for short exposure time periods is the preferred method of
effecting maximum cure strength. This is true for the great majority of applications and
will not normally damage the guides.
However, care must be taken to minimize very high intensity levels for sustained periods
of exposure time. Also, the special IR reduction filter in AUV/LESCO SUPERSPOT cure
systems must not be removed. If either of these conditions occurs, the LF lightguide will
suffer irreparable damage or have its service life reduced dramatically. Special duty
AUV/LESCO FO lightguides are available for extreme intensity/dosage applications
(contact factory at 1-800-615-3726).
Never bend a light guide radically (i.e. - over 90
°
over a 12” radius for a LF). Be
extremely careful not to scratch, mar or accidentally apply curable material to the guide
end tips. Clean the quartz end tips with alcohol on a regular basis and check
transmission levels at least every 100 operating hours (more often if end tips are not
fixtured).
6.10. Fiber-optic
AUV/LESCO fiber optic (FO) lightguides are used for applications where long run lengths,
tight end clearances, or multiple outputs are required. FO lightguides are available in
almost endless configurations for specialized applications. Popular standard products
are Bi-, tri- and quadfurcated guides, although AUV/LESCO FO lightguides can be
ordered with 10 or more output ends arranged in circular, line or any random
configurations.
Your Fiber Optic Light Guide (FOLG) is designed to provide a long life of dependable
and consistent UV energy transmission. In order to sustain the high levels of throughput
and extend its useful life, the FOLG must be properly maintained.
Following are some general maintenance guidelines for your reference. If you need any
additional help or have further questions, please contact AUV/LESCO with your request.
1. Inspect the FOLG regularly. A visual inspection of its ends will detect most problems
associated with build up of residues or signs of deterioration. To inspect it, use a
bright incandescent lamp. It is better to cover the opposite end to prevent back
illumination. The surface should look black and very shiny. If it looks dull or not glossy,
there is residue on it and it should be cleaned.
2. Never use a sharp object to clean the fiber surfaces. Use only high quality solvents.
We recommend using reagent grade acetone. Do not use regular acetone as it may
leave residues.
