Re-examine the window after removing the dust. If a smudge is still visible, proceed by dipping a
clean, lint-free cotton swab in ethyl or isopropyl alcohol. The swab should be saturated, but not
dripping.
6.
Carefully draw the swab once across the surface, then rotate the swab 180 degrees to expose the
fresh surface and draw it across the window surface again. Be careful not to pool alcohol on the
glass surface.
7.
Re-examine once again and repeat the process once, if necessary.
If contamination continues to be a problem, please call Thorlabs for assistance.
CAUTION
Ethyl and isopropyl alcohols are highly flammable! Do not use near extreme heat, arcing electrical
equipment (such as space heaters) or open flame! Use only with proper ventilation. Follow all safety
instructions provided by the manufacturer of the alcohol product.
