1.
Remove the camera from the optical assembly and bring the camera to a clean, dry location
where it is safe to use flammable solvents (please see
“Caution” below)
2.
Remove any CS-mount or C-mount lens adapters from camera.
3.
Orient the camera so that the sensor is pointing downward and carefully unscrew the SM1
retaining ring and remove the window or filter. Refer to Section 3.6.1.
4.
Place the camera face down on a clean, dry surface to prevent particles from accumulating on
the
sensor’s faceplate.
5.
Once the filter is removed, Use a CLEAN, DRY (preferably brand-new), camel hair lens cleaning
brush (such as those used by photographers) to gently wipe the particles off of the filter.
6.
Re-examine the filter after removing the dust. If a smudge is still visible, proceed by dipping a
clean, lint-free cotton swab in ethyl or isopropyl alcohol. The swab should be saturated, but not
dripping.
7.
Carefully draw the swab once across the surface, then rotate the swab 180 degrees to expose
the fresh surface and draw it across the filter surface again. Be careful not to pool alcohol on the
glass surface.
8.
Re-examine once again and repeat the process once, if necessary.
If contamination continues to be a problem, please call Thorlabs for assistance.
CAUTION
Ethyl and isopropyl alcohols are highly flammable! Do not use near extreme heat, arcing electrical
equipment (such as space heaters) or open flame! Use only with proper ventilation. Follow all safety
instructions provided by the manufacturer of the alcohol product.
