Basic Optical Alignment Procedure
1. Display a test pattern appropriate for analyzing image focus and geometry, such as a single crosshair
centered across the image.
2. Course focus. Do a quick preliminary (center) focus and (if available) zoom adjustment with the primary
lens only. Refer to Section 3.14 Working with the Lenses in the Roadie HD+35K User Manual.
3. Center the image in the lens. Holding a piece of paper (full white field) at the lens surface, adjust offsets
until the image on the paper is centered within the lens perimeter.
4. Re-check side-to-side levelling. With a test pattern on screen, double-check projector leveling (refer to
Section 2.2 Projector Position and
of the screen.
