Uneven illuminance correction mechanism
The exposure system ensures that light is distributed
evenly on the original. Reflected light radiates to the
OPC through the lens (F8, f=230 mm). The slanted
lines in the figure show light distribution.
The lens filter ensures that light is evenly distributed on
the OPC. To correct uneven illuminance on the original
face, six auxiliary reflectors are provided, and two
adjusters are also provided on the front and rear
reflectors.
Front and rear auxiliary reflectors adjustment
Turn the hexagonal socket head clockwise in the
direction of the arrow to raise the adjusting nut. The
holder can be moved in the direction of the black arrow
with its axis used as a fulcrum. The front (or rear)
reflector can be adjusted to correct uneven illuminance.
