should be secured into place using the eight projector standoffs provided. Two of the standoffs have a removable hook and loop material to be used at the rear of the projector for ease of removing the projector. The standoffs will en- sure proper relocation of the projector after periodic maintenance or repair to the projector. Just peel the adhesive backing from the bottom of the standoffs and place them around the projector as shown in the dimensional diagram.
Important: Once the adhesive is placed onto the surface of the inner pan it is very difficult to remove. It is very important to plan ahead when placing these standoffs around the projector.
Choose a projector* based on its light path
A light path is the projector’s spread of light and its relationship to the cen- terline of the lens. Since the Revelation folds a light path twice (bounces the image off of two fi rst surface mirrors), it’s critical to understand your projector’s light path to know approximately where the image will land on the wall. Con- sult the projector's manufacturer to determine its light path geometry.
Single lens projectors fall into one of four categories of light path geometry as depicted in the illustrations at right.
Light Path A
Single lens projectors with light path geometry “A” work well with the Reve- lation. Since the light is already projecting at a downward angle to the cen- terline, the image is projected further down on the wall resulting in a lower installation point for the projection screen. A projector with Light Path A mounted in the Revelation projects a light path similar to the same projector ceiling mounted with the centerline of its lens mounted approximately 51- 76mm
Light Path B
Single lens projectors with light path geometry “B” will work with the Reve- lation within certain limitations. The upper edge of the image runs parallel to the centerline of the lens. A projector with Light Path B mounted in the Revelation projects a light path similar to the same projector ceiling mounted with the centerline of its lens mounted approximately
Light Path C
Single lens projectors with light path geometry “C” will work with the Reve- lation within certain limitations. The portion of the image above the centerline of the lens projects at a gradual angle up towards the ceiling. A projector with Light Path C mounted in the Revelation projects a light path similar to the same projector ceiling mounted with the centerline of its lens mounted approximately
Light Path D
Single lens projectors with light path geometry “D” will not work with the Rev- elation. The portion of the image above the centerline of the lens projects at too steep of an angle to be lowered below ceiling level, even with the adjust- ment features built into the Revelation.
*Consult your projector manufacturer if in doubt about its light path geometry, throw distance or projector dimensions. Also, be sure your projector has the ability to invert its image.
