CAUTION
If the lens or soft anti-reflective coating is scratched, the lens must be replaced.
Call your local Beckman Coulter Representative.
8
Carefully inspect the lens' surface for cleanliness by shining a bright light on it and looking at
the surface from all angles.
9
Dock the sample module back into the instrument.

Projection Lens
Use this procedure to clean the projection lens. To clean the projection lens:
1
If a sample module is docked, undock it, if not, open the Optical Module's door.
CAUTION
Use lens tissues only once, then discard. Never use siliconecoated, eyeglass lens
tissues to clean lenses. They can leave a film. Wash your hands thoroughly before
cleaning any lens or sample cell window. Do not touch optical surfaces with your
fingers or skin. Body oils are difficult to remove from lenses without harming the
anti-reflective coating.
2
Fold two or three lens tissues in half.
3
Squirt lens cleaner onto the folded lens tissues.
4
Place your finger in back of the lens tissue(s).
5
Starting at the outermost edge of the component, wipe in a spiral pattern to the middle. Refer
