2.9.4 Add Anamorphic Lens

1. Install the Auxiliary Lens Mount according to instructions provided in the kit. Make sure to optimize your
primary lens first for best optical alignment, offset and boresight.
2. Image geometry distortion: Loosen the holding clamp on the auxiliary lens mount. Adjust the rotation of
the anamorphic lens so the image remains perfectly square with anamorphic in and out.
3. Image shift: Adjust the location of the anamorphic lens so that the image does not shift left or right with
the anamorphic lens in and out.
4. Vignetting: Adjust the location of the anamorphic lens so the image passes through the center as much as
possible without vignetting, reducing side or corner brightness, especially in wide angle projection.
5. Focus primary lens: With the anamorphic lens not in place, re-focus the primary lens using the Focus
knob. The goal is for good focus at the center and on all sides. Now add the anamorphic lens and check
focus again.
6. Focus anamorphic lens: If center-to-edge horizontal focus in the image needs improvement, focus the
anamorphic lens by rotating its focus barrel as needed.

2.9.5 Wide Converter Lens

1. Install the Auxiliary Lens Mount and Wide Converter Lens (WCL) according to instructions provided in
the kit. Make sure to optimize your primary lens first for best optical alignment, offset and boresight.
2. Image shift: Adjust the vertical and horizontal position of the WCL to align it with the already adjusted
prime lens.
3. Pitch Adjustment: Adjust pitch, either up or down to equalize the top and bottom clearance to the prime
lens barrel.
4. Yaw Adjustment: Adjust yaw to make the clearance between both lens barrels equal from side-to-side.

2.10 Fold Mirror and Convergence Adjustments

In rare instances, shipping and handling may affect the precise factory alignments of one or more optical
components. As a final step of installation, the installer may have to adjust the fold mirror and/or convergence
of the DMDs.

2.10.1 DMD Convergence

A convergence problem is evident when one or more projected colors (red/green/blue) appears mis-aligned
when examined with a proper convergence test pattern. Normally, the three colors should overlap precisely to
form pure white lines throughout the image. One or more poorly converged individual colors may appear
adjacent to some of the lines. Qualified service technicians can correct the problem by following the
instructions on the color label provided on the inside of the front top lid.
