Section 2: Installation and Setup
9. Position the lens clamp DOWN to lock the lens assembly in place.
10. Calibrate the lens. See
11. Install the shroud.
2.11 Install the Optional Anamorphic Lens
1. Make sure to optimize your primary lens first for best optical alignment, offset and boresight.
2. Install the auxiliary lens mount using the instructions included with the kit.
3. 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.
4. Adjust the location of the anamorphic lens so that the image does not shift left or right with the anamorphic
lens in and out.
5. 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.
6. Remove the anamorphic lens and turn the Focus knob to re-focus the primary lens. The goal is for good
focus at the center and on all sides.
7. Re-install the anamorphic lens and check the focus.
8. If center-to-edge horizontal focus in the image needs improvement, rotate the focus barrel.
2.12 Install the Optional Wide Converter Lens
1. Optimize the primary projector lens for optical alignment, offset, and boresight.
2. Install the Auxiliary Lens Mount and Wide Converter Lens (WCL) using the instructions included with the
kit.
3. Adjust the vertical and horizontal position of the WCL to align it with the primary lens.
4. Adjust the pitch, up or down to equalize the top and bottom clearance to the primary lens barrel.
5. Adjust yaw to make the clearance between both lens barrels equal from side-to-side.
