How to clean instruments with a recessed lens interface
Light dirt
If you nd any particles of dirt on the xed connector interface , or on the input
of the optical block, clean them with compressed air .
This cleaning method is gentle to your optical device and is an ideal approach if
there is no fat on the surface of your device .
Heavy dirt
Using compressed air , blow away larger particles of dirt. Clean the recessed lens
interface with a dry cotton swab by rubbing gently over its surface . Then blow
away any remaining laments left by the swab .
Isopropyl alcohol should only be used if there is fat on the lens . In this case ,
choose a new swab and moisten it with alcohol. Remove the dirt by gently
rotating the swab using light pressure . Then select a fresh, dry swab to wipe
away the alcohol. Blow away any remaining lament with compressed air .
Caution
Do not press the swabs too hard onto the optical surface of your
device , as this may produce scratches and your recessed lens
could be misaligned.
Alcohol will dissolve some types of dirt. If this then forms a
deposit on the edge of the optical input it cannot be removed.
Y ou should therefore only use alcohol if absolutely necessary .
Other solvents , like A cetone , should also not be used, as they
may damage your optical device and reduce its performance .
