1 . PROJECTOR LENS CALCULATION FORMULAS
1. THROW DISTANCE / RATIO = SCREEN WIDTH
2. SCREEN WIDTH x RATIO = THROW DISTANCE
3. THROW DISTANCE / SCREEN WIDTH = RATIO


2 . What is a 2.35 Constant Height Setup?

In basic terms, its the ability to watch 2.35 material in full resolution and with full width just as the director intended. In a constant height setup 2.35 movies take up the whole screen without any black bars above/below.


3 . Panamorph 2.35:1 Q&A
Published on www.panamorph.com

How does the Panamorph anamorphic lens system work? For the best demonstration of how a Panamorph lens system delivers the full impact of major motion pictures into your home, please watch the GET THE PICTURE video on our home page. For maximum impact, please make sure your ?favorites? or ?history? window is closed and go to full screen on your browser (on PCs this can be accomplished by simply hitting your F11 key).

What movies are available in the True Widescreen 2.40:1 / 2.35:1 or greater ratio? A quick check through your current DVD, Blu-ray or HD-DVD collection will probably reveal that the majority of movies you already own are in the 2.35:1 or greater ratio. Simply look on the back cover and you will probably see the ?this movie is in letterbox format ? the black bars at the top and bottom of your screen are normal? along with a ?2.35:1,? ?2.39:1? or ?2.40:1? designation. Almost all of these films will work properly with a Panamorph lens system and compatible scaler / projector. This is also true of many high definition movies on TV, cable or satellite.

What do I need in addition to a Panamorph lens system to make all of this work? Here is what you need to create a True Widescreen image in your home theater:
1. A 16:9 home theater projector
2. The proper scaling mode to create a vertically stretched anamorphic image, either built into the projector itself or in a separate component (most current projectors have this scaling built in, or if necessary a separate scaler can be installed by your Panamorph dealer).
3. A projection screen with the proper aspect ratio (we recommend a 2.40:1 ratio screen)
4. Source material ? in other words, movies shot in the 2.35:1 or greater aspect ratio (over 70% of the top grossing movies of all time). These are available on DVD, Blu-ray, HD-DVD, or high definition TV, cable or satellite.
Will the Panamorph UH480 lens work with ?XYZ? projector? In all likelihood, yes. The Panamorph UH480 lens was designed with a very large aperture so that it would even accommodate projectors with very large lenses or beam spots. Having a large aperture also means that the UH480 will work through the entire zoom range of most projectors, which greatly eases installation concerns. Our AKXPRO Universal Attachment Kits work with the vast majority of home theater projectors on the market.

How does the Panamorph UH480 lens mount to my projector? The easiest way is to use our AKXPro Universal Attachment Kit ("X" refers to a version number), which includes a mounting plate that attaches the UH480 lens to most popular projectors on the market today. This in turn attaches to your projector ceiling mount.*

Here is a list of projectors compatible with our current AK7PRO Mounting Plate:
BenQ 8720, W9000, W10000,W5000, W20000 Epson PowerLite 1080 InFocus IN series InFocus 7205, 7210 InFocus 777
