Procedure
•
Use localized ionized air flow on to the glass during sensor cleaning.
•
Blow off mobile contamination using an ionized air gun.
•
Place the sensor under the microscope at a magnification of 5x to determine the
location of any remaining contamination.
•
Clean the contamination on the sensor using one drop of E2 on a swab.
•
Wipe the swab from left to right (or right to left but only in one direction). Do this in
an overlapping pattern, turning the swab after the first wipe and with each
subsequent wipe. Avoid swiping back and forth with the same swab in order to
ensure that particles are removed and not simply transferred to a new location on
the sensor window. This procedure requires you to use multiple swabs.
•
Discard the swab after both sides of the swab have been used once.
•
Repeat until there is no visible contamination present.
