10 Filter Alignment10. Filter Alignment


Align filter assemblyThe 3D Lens assembly ships with filter assemblies attached in the retracted position as shown.

The filters are not aligned at the factory. They must be alignedfactory. They must be aligned after the 3D lens alignment to match theater conditions.

If filters are ever removed fromIf filters are ever removed from the projector, please note that there both filters are not identical. The proper orientation i h th filt ith this shown, the filter with the “RealD” logo should always be on top.

the filter may need to move to its forward limit.

Set bottom filter.

Set bottom filter to match angle and position of top filter. Assure that the beam is not clipped by the hardware surrounding the filters and the ghost image is eliminated.

Tighten plastic knobs securely.


Tighten plastic knobs securely.

Mark settings.

If the 3D lens assembly should be removed and placed into its storage box, the filter assembly will need to be retracted so that the assembly will fit into the box. This deletes the filter alignment. To make it easy to recapture these settings for the same theater, mark the g ,side brackets with any marker that can be seen as shown.

Although this will revive the previousAlthough this will revive the previous alignment, it is important to verify that the beam is not clipped after re-installation.


11. Storage of 3D Lens and Filters

Figure 12 Lens Assembly Packing CaseFigure 12. Lens Assembly Packing CaseThe 3D Lens Assembly is shipped in its packing case with the filters fully retracted.The assembly should always be safely stowed back in its case when not mounted on the projector.Depending on the positions of the filters however, you may need to retract them before stowing the assembly.Note that It is possible to extend the storage area of the case by pulling out the removable foam strips.


p g y p g pThe storage case may be used to store your 2D lens as well while showing 3D presentations.
