Hi,
Kimwipe is a lint-free paper. I am wondering whether Kimwipe can be used to clean microscope lenses and to wipe out from oil lenses without damaging.

I wouldn't trust it to not leave scratches. Lens paper isn't that expensive; and it's designed specifically not to damage your lenses...

Just a note. I've used Kimwipes for at least 11 years and absolutely no scratches , approx. 10,000 'scopes.


For what use? We recently had to repair a rather expensive lens due to damage associated with abrasion of the lens coating. One of the potential causes of the damage, according to Zeiss, was use of non-lens paper for cleaning the lens (kimwipes was listed as an example "bad" material). Lower resolution lenses may not be effected by minor scratching of the lens, but for those of us working with high NA lenses, near or at resolution limits, even small scratches and abrasions can have notable detrimental effects.
