III. Lens Cleaning Procedure.
To minimize the possibility of damaging the optical coating or scratching exposed lens surfaces, we have
developed recommendations for cleaning lenses. 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.
A TorayseeTM cloth is included with the lens kit.
Proceedas follows :
1.Alwayswipe lenses with aCLEAN TorayseeTM cloth.
2. Always wipe lenses in a single direction. Do not wipe back and forth across the lens surface as this tends
to grind dirt into the coating.
3. Do not leave cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.
4. If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty cloth.
5. Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the cloth.
6. Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
Order number for a new TorayseeTM cloth : R379058.
