Runco CL-810 ULTRA, CL-810 CINEWIDE, CL-810 / SDC-1 manual Geometry

Installation

Correct Lens Angle

Incorrect Lens Angle

The anamorphic lens will almost always be angled with respect to the projector; this is normal. Once the proper lens angle has been set, firmly tighten the Pitch Adjustment T-Screws to secure the lens in place.

Note

Geometry:

There may be some pincushion distortion even after the lens is properly adjusted, especially at shorter throw distances. If this is the case, Runco recommends that you slightly over-scan the image into the screen frame area to mask the distortion.

1.Input an anamorphic cross-hatch test pattern to the projector.

2.Unscrew the Anamorphic Lens just enough to allow it to rotate freely.

3.Grasp the lens by the center ring and rotate the lens until the image is properly anamorphic:

Wrong Position Correct Position

4.When the image geometry appears correct, tighten the Anamorphic Lens Set Screw (item #10) to secure the lens in place. (When viewed from the front, the rear opening on the anamorphic lens should appear as a tall, narrow oval.)

Focus: Finally, rotate the Focus Ring on the anamorphic
lens to fine-tune the optical focus.	S
