2.7.3 Add Anamorphic Lens

1. Install the auxiliary Lens Mount according to instructions provided in the kit (P/N 108-111101-02, P/N

108-111102-xx). 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 rotation of

anamorphic lens so the image remains perfectly rectangular with anamorphic in and out.

3. Image shift: Adjust location of anamorphic lens so that the image does not shift left or right with the

anamorphic lens in and out.

4. Vignetting: Adjust location of anamorphic lens so the image passes through the center, as much as

possible, without vignetting or 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.

2.7.4 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.

2.8 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.

2.8.1 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 - where normally the 3 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 all of the lines. Qualified service technicians can correct as described on the color label

provided on the inside of the front top lid.
