Adjusting the anamorphic lens
Before use, the anamorphic lens needs to be adjusted so that:
• it is parallel to the projection lens in both horizontal and vertical planes,
• the centres of the two lenses are in line, and
• the anamorphic image expansion is horizontal.
Vertical plane
• Adjust the two screws, ensuring that after adjustment, both screws are in contact
with the vertical support.
Horizontal plane
• Loosen the locking screws, and rotate the two bearings, ensuring that after
adjustment, both bearings are in contact with the horizontal support.
Vertical position
• Adjust the two screws, ensuring that after adjustment, both screws are in contact
with the lens holder.
Horizontal position
Two microswitches are located at each end of the lens carriage, on the side nearest
the projector. The central bracket determines the horizontal position of the lens
when the lens is moved into position.
• Adjust the position of the central microswitch bracket.
Lens rotation
• Loosen the lens clamp and rotate the lens within the lens holder.
