2.10.1 Basic Optical Alignment Procedure
1. Display a good test pattern appropriate for analyzing image focus
and geometry, such as a single crosshair centered across the image.
2. COARSE FOCUS: Do a quick preliminary focus by rotating the
focus adjustment knob directly under the lens. For best results, use
a crosshatch test pattern or similar, and focus on the center of the
image. If available, zoom adjustment with the primary lens only.
Do not worry about consistency across the image at this point, just
center focus.
3. CENTER THE IMAGE IN THE LENS: Holding a piece of paper at the lens surface, adjust offsets as
necessary until the image is centered within the lens perimeter. A full white field works best for this.
4. RE-CHECK SIDE-TO-SIDE LEVELING: With a good test pattern on screen, double-check projector
leveling (refer to Section 2.3 Projector Position and Mounting ) so that the top edge of the image is parallel
to the top edge of the screen. See Figure 2-33 .
2.11 Offset and Boresight Alignment
To ensure proper offset for your site and consistently good focus in all areas of the screen, a primary lens must
be installed and its lens mount precisely adjusted in relation to internal optics as described below. If desired, an
auxiliary lens can then be added to widen images for scope cinema displays.
Warning! 1)
If the Motorized
Auxiliary Lens Mount (MALM) is present, ensure to move the MALM to the OUT position before performing
any lens calibrate or reset functions on the Motorized Primary Lens Mount to prevent collision between the
projection lens and the MALM.
2)
Hazardous moving parts. Keep fingers and other body parts away.
NOTES:
1)
Projector must be fully assembled and powered up in its final location.
2)
Keep clear of rotating parts.
Remotely operated motors may start to spin without warning.
3)
Avoid long hair, jewelry, and loose clothing
exposure to the knobs during manual adjustment.
4)
In case of emergency, unplug the line cord to immediately
halt movement of the lens mount.
