Add Anamorphic Lens; Internal Optical Adjustments; Contrast Ratio Adjustment - Christie Roadie HD+35K User Manual

3. Adjust the vertical boresight bolt
the bottom hex screw and another to turn the adjustment bolt above it.
Adjust as necessary to direct or "aim" the lens toward the edge of the image
which focused too close to the lens. When both top and bottom appear
equally blurry, re-focus at the top of the screen.
4. Adjust vertical offset to re-center the image on the screen.
5. Repeat steps 8 and 9 until the top and bottom of screen are both well
focused.
6. Refocus. Although all sides of the image should now be in focus, the center
of the image will be slightly blurry at this point. Refocus at center of image.
The goal is good focus at center and on all sides.
7. Adjust the "lock" screw to lock in place, and check boresight again.

2.12.4 Add Anamorphic Lens

If present, swing the anamorphic lens in position in front of the primary lens. It should magnify in the
horizontal direction only, stretching the image straight across the screen-this requires that its aperture (visible
within the lens) be vertically aligned with the screen. If the image appears skewed, loosen the locking ring on
the anamorphic lens and rotate the lens as necessary until the wide image is horizontal.
1. Focus primary lens. With the anamorphic lens in place, re-focus the primary lens. The goal is good focus
at center and on all sides.
2. Focus anamorphic lens. If horizontal focus in the image needs improvement, focus the anamorphic lens
too-rotate its barrel, as needed.

2.13 Internal Optical Adjustments

In rare instances, shipping and handling may affect the precise factory alignments of one or more optical
components-as a final step during installation, a trained installer may want to adjust the fold mirror and/or
convergence of the DMDs as described here. In addition, for certain applications and sites you may prefer
images having increased contrast ratio and/or the widest possible color gamut, both of which require the
addition of internal optical components (sold separately) that will slightly reduce brightness.
NOTE:
A Christie accredited service technician is required.

2.13.1 Contrast Ratio Adjustment

To achieve increased Contrast Ratio, and if desired, the standard F# Aperture installed at the factory can be
replaced with an optional smaller aperture that improves contrast ratio while slightly limiting brightness.
NOTES: 1)
Some lamps may be incompatible with some apertures, and it is therefore advised that you use only the
size(s) recommended for the lamp currently installed in the projector. Follow the installation instructions
provided with the F# Aperture Kit.
The factory-installed standard-size aperture (for maximum brightness) is not labeled.
