14.7 Cleaning the lens
To minimize the possibility of damage to optical coatings, or scratches to lens surfaces, we have developed
recommendations for cleaning. FIRST, we recommend you try to remove any material from the lens by blowing
it off with clean, dry deionized air. DO NOT use any liquid to clean the lenses.
Necessary tools
Toraysee® cloth (delivered together with the lens kit). Order number : R379058.

2. W ipe lenses in a one single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. D o not leave the cleaning cloth in either an open room or lab co at pocket, as doing so c an contaminate the cloth.
4. If smears occur when cleaning lenses, replace the cloth. Smea rs are the first indication of a dirty cloth.
CAUTION: Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the
cloth.
Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
