1 CLEANING THE PLASTIC CAP
Care should be taken when cleaning the surface to prevent scratches.
The optical characteristics of the CCD will be degraded if the cap is scratched during
cleaning.
We recommend cleaning the cap with a soft cloth moistened with one of the recommended
solvents below. Excessive pressure should not be applied to the cap during cleaning. If the
cap requires multiple cleanings it is recommended that a clean surface or cloth be used.
