Optoma Anamorphic Lens and Sled Kit Part# BX-AL133B $6499

Why Anamorphic? Hollywood releases more and more movies in Cinemascope format Most of 1080p releases are in Cinemascope 2.35 type of format Cinemascope introduced in 1953 by Hollywood after advent of 4:3 TV’s (35mm film is squareish like 4:3) Films are shot in wide CinemaScope formats but are Anamorphically stretched vertically to fill available space on 35mm film frame This vertical stretch is then corrected at the movie theater with a horizontal Anamorphic lens correcting the geometry. Even Digitally shot HD films are being produced in 2.35 format Attain more brightness with 25% bigger image vertically and 33% wider!

Non Anamorphic “Cinemascope” on 35mm When Hollywood first shot wide on 35mm film they got this as the result. They realized they would waste film space by doing this. They needed a vertical anamorphic lens to fill the frame completely.

Anamorphic 2.35 Scene on 35mm This illustrates a wide lens shot on 35mm film with the use of an vertical anamorphic lens during filming. This has the effect of squeezing the image making it look as if it is vertically stretched. The geometry will be corrected at the film theater with a Horizontal Anamorphic lens and correct the geometry to the viewer.

Anamorphic 2.35 Image at Movie Theater The image that is displayed to the viewer is geometrically corrected by the Horizontal Anamorphic lens at the movie theater.

1920x1080 Projectors Native aspect ratio is 16:9 or 1.77:1 (1.78) Widescreen (Scope / Panavision) is 2.35, 2.39, or 2.4:1 In order to preserve and display 100% of the image the projector will Letterbox the image with matte black bars above and below image The combination of Anamorphic lens and digital (scaler) vertical stretching will reproduce a true “Scope” 2.35 image

2.35 in 16:9 A typical letterboxed 2.35, 2.39, or 2.4 “Scope” movie displayed on a 16:9 projector or display.

Vertical Stretch 25% Vertical Resolution Our projectors can vertically stretch the image to fill in the black bars of a letterboxed image by using the LBX display function. The result, however, is a geometrically incorrect image. It will take either a Horizontal anamorphic expansion lens or a vertical anamorphic compression lens to display the image correctly. Optoma sells the Horizontal expansion lens. It physically expands the 16x9 width by a factor of 1.33x. The height stays the same as this type of lens provides a constant height from 16x9(1.78) to 2.35. A vertical compression anamorphic lens would do the opposite and maintain a constant width while compressing the image height..

Anamorphic 2.35 Video Image 1.33X Wider than 16x9 This result is with the use of a horizontal expansion anamorphic lens that Optoma sells.

Anamorphic Lens (BX-AL133B) The Anamorphic process is to reshape or form a new image. From root word Anamorphis. The BX-AL133 Lens performs the same function with video as Anamorphic lenses perform with traditional Film projectors at movie theaters. It corrects image geometry by widening the image horizontally. Anamorphic video process is a two step process. First the projector scales the image vertically eliminating black bars of a letterboxed movie. This enables you to gain full vertical resolution (1080p) 25% more than letterboxed image. Second, the Anamorphic Lens is triggered via a 12V trigger and the motorized sled positions the lens in front of projector lens giving you a full 1.33X wider “Scope” image. Just as in the movie theaters!
