Do not clean the mirrors in the body and certain projection heads because
they are front-surface mirrors.
Front surface mirrors have their
reflective surface on the front of the glass.
These mirrors do not
reduce the image intensity or clarity as do conventional mirrors. Remove
any surface dirt in these mirrors with a camel's hair brush.
NOTE:
Use figure 2-21 to follow the discussion of an opaque projector.
