4.4
Adjust Offset
Project an image with the primary lens. Always
adjust offset before boresight.
Select a framing test pattern and then adjust the
horizontal and vertical offset to display a square
image on the screen with minimal cinema
projector aiming error. (
Figure 4-1
)
NOTES:
1)
For the best optical performance and
minimize keystone error, use offset and not aiming
to center the image in off axis installations.
2)
Avoid extreme tilts or offsets. Corner vignettes on
a white test pattern indicate extreme offset that
should be avoided using mechanical alignment.
4.5
Adjust Offset with an ILS
Project an image with the primary lens. Always
adjust offset before boresight.
Ensure the correct
lens is selected in the Advanced Setup: Lens
Adjust window before calibration to ensure you
remain within the applicable boundary of the
installed lens

keystone error by using offset more than aiming to center the image in off axis installations. Avoid extreme
tilts or offsets. Corner vignettes on a white test pattern indicates extreme offset that should be avoided
using mechanical alignment
.
4.6
Adjust Left and Right Boresight
When performing these adjustments the goal is to balance the tilt of the lens mount to compensate for screen to
cinema projector tilt, but also to precisely maintain the original factory settings of the lens mount axial
position.
1. Loosen the horizontal hold screw.
2. Extend the lens focus completely.
