Cleaning a Contaminated Optic. Refer to Figure 8-13. To clean an optic that is fogged
or contaminated with other than dust or dry dirt:
1.
Hold the optic horizontally by its edges.
2.
Place one small drop of acetone in the
center of a sheet of lens paper.
3.
Contact the optic completely with the
wet part of the lens paper. Any gap
between the optic and the lens paper
may result in uneven cleaning.
4.
Wipe the optic with the lens paper by
pulling one end of the lens paper slowly
and steadily until the other end of the
lens paper comes off the optic. Any
gap created between the lens paper and
the optic during wiping, as well as
acetone remaining at the end of the lens
paper without evaporating, may result
in uneven cleaning.
5.
Shine a fluorescent lamp onto the cleaned parts to confirm that no dirt or dust
remains.
Reassembling the Optical Components. To reassemble the optical components in
the input focusing unit:
1.
Assemble the optical components in the reverse order of their removal.
2.
After assembling the optical components, verify that there is no dust, dirt or
uneven cleaning spots. Be sure that the optics do not collect any dust or dirt
during installation.
Optical Fiber Cleaning. To clean the
optical fibers:
1.
Refer to Figure 8-14. Remove the
optical fiber from the mating connector.
2.
Refer to Figure 8-15. Blow away any
dust on the end surface of the fiber.
