11. Maintenance and Troubleshooting
11.1 Maintenance
Kronos does not contain any consumable items or spare parts. The exterior of Kronos can be
cleaned with a soft cloth moisten with ethanol. Never use acetone. Replace the lids to ensure no
contaminants or dust will fall into the modules. Avoid cleaning inside the modules due to the risk
of optics and crystal contamination, and accidental misalignment. If absolutely necessary, ensure
sufficient ventilation to minimize fume concentration in the modules.
Clean optical surfaces allow for optimal reflection or transmission of laser power. Contaminants
on the optics can reduce the efficiency of the system. Touching the polished surface of the optics
in anyway, even with new gloves, can cause contamination. It is crucial that optics are handled at
the ground edges only. Exercise caution when handling optics and when cleaning them. Always
inspect the optics before and after cleaning them. Use a magnification device and a bright light to
spot small defects and contaminants.
Clean optics in increasing level of contact. Use non-contact methods by blowing off dust and other
contaminants with compressed air. Be careful not to use excessive pressure that might cause the
optics to slip or crack.
If blowing is not sufficient to remove remnant contaminations, e.g. oils, spectroscopic-grade
methanol is the recommended solvent for cleaning optics. Other solvents and poorer grades can
leave residues or degrade the optical coatings. Always read the associated data sheets and MSDS
sheets prior to using any solvent.
Prepare a single piece of high-quality lens tissue, folded neatly, and lightly moistened with the
solvent. Gently use the tissue for one wipe and one direction only and discard it immediately. Use a
new tissue for subsequent passes. Reusing the tissue or reversing direction can drag contaminants
back across the cleaned surface, causing residual streaks and potential damage.
