Yaw Adjust: Loosen the Yaw/X-Adjustment Levers to allow the lens to pivot freely from
side to side. Then, angle the lens to even out any left-right pincushion distortion:
Once the proper lens angle has been set, firmly tighten the Yaw/X-Adjustment Levers to
secure the lens in place.
Geometry:
1. Input an anamorphic cross-hatch test pattern to the DHD Controller.
2. Loosen the three Lens Rotation Set Screws (shown
at right) on the lens adapter plate just enough to
allow it to rotate freely.
3. Grasp the lens by the front ring and rotate the lens until the image is properly
anamorphic:
4. When the image geometry appears correct, tighten the three Lens Rotation Set Screws
to secure the lens in place.
Focus: Finally, rotate the Focus Ring on the anamorphic lens to fine-tune the optical
focus. When finished, hand-tighten the Focus Rotation Set Screw to lock the lens in
position.
