3. Use a clean Q-tip or Clean-wipe to scrub the surface when applying the solvent. Make
sure no material “bleeds” from the surface, as this is an indication that there has been
mechanical damage.
4. Be careful not to expose the mono-coil jacket (black flexible tubing) surface to the
acetone. Do not use any solvents that can dilute epoxy adhesives. Use alcohol to
clean any deposits on the mono-coil surface.
5. If the fiber surfaces cannot be cleaned or continue to release material, please return
the FOLG to AUV/LESCO for repair. It may be necessary to re-polish the surfaces or
rebuild the ends.
6. Always inspect the IR filter in the Super Spot unit, since it is essential for the
protection of the proximal (entrance) end of the FOLG. Using the FOLG with a
damaged, broken, or removed filter will cause serious damage to the fiber.
Following these general guidelines and proper preventive maintenance will give you the
expected long life of your FOLG. Please make sure you keep it clean and working
properly to benefit from its unmatched performance.
6.10.1. All Lightguides
All lightguides can be damaged or suffer impaired light transmission if not used properly.
Transmission losses can be easily determined by using a AUV/LESCO Quartz Calibration
Fixture and radiometer. FOLG have lower transmission efficiency than LFLG, usually in
the 30 to 40% range, but their operating life is several times longer, making them a very
cost effective delivery method. To check the percentage transmission, consider the
Calibration Fixture transmission as 100%. Simply divide the FOLG reading by the
Calibration Fixture value to compare results with previous readings. In Optical Feedback
units, the level potentiometer must be set to minimum to override its operation. Reset the
UV output level after checking transmission.
