Install The Optional Wide Converter Lens - Christie CP4230 User Manual

Section 2: Installation and Setup
3. Adjust location of anamorphic lens so the image does not shift left or right with the anamorphic lens IN
and OUT.
4. 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. With the anamorphic lens not in place, re-focus the primary lens. The goal is good focus at center and on
all sides. Now add the anamorphic lens and check focus again.
6. If center-to-edge horizontal focus in the image needs improvement, rotate the focus barrel.

2.13 Install the Optional Wide Converter Lens

1. Install the Auxiliary Lens Mount and WCL according to the instructions provided with the kit. Ensure the
primary lens is optimized first for best optical alignment, offset and boresight.
2. Adjust the vertical and horizontal position of the WCL to align it with the already adjusted prime lens.
3. Adjust pitch, either up or down to equalize the top and bottom clearance to the prime lens barrel.
4. Adjust yaw so the clearance between both lens barrels is equal from side-to-side.
