SWmin: 1m (39.37inch)

SWmax: 6m (236.22inch)

1.6 Cleaning the lens

To minimize the possibility of damaging the optical coating or scratching exposed lens surface, we have de-

veloped recommendations for cleaning the lens. 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

TorayseeTM cloth (delivered together with the lens kit). Order number : R379058.

Howtocleanthelens?

Proceed as follow :

1. Always wipe lenses with a CLEAN TorayseeTM cloth.

2. Always wipe lenses in a single direction.

Warning: Do not wipe back and forwards 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.

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.

Other lenses can also be cleaned safely with this TorayseeTM cloth.
