Do not clean the mirrors in the body and certain projection heads
because they are frontsurface 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 221 to follow the discussion of an opaque projector.
