BX-AL133B − Anamorphic Lens

With Optoma’s anamorphic lens, the option to create a true cinematic setting is easier than ever. The Optoma BX-AL133B Anamorphic Lens offers true 2.35:1 aspect ratio in genuine movie theater style to match many of today’s DVD and HD offerings.

Optoma’s BX-AL133B anamorphic lens is easy to install and will work perfectly with a home theater projector that is either sitting table-top or mounted. The accompanying mounting bracket can be attached directly to the ceiling or a projector plate. A self-made riser block may be needed if the bracket itself does not allow for proper positioning.

To use: Mount the BX-AL133B as close to the projector lens as possible, so that the projector beam enters the center of the rear lens opening. Leave enough room to tilt the anamorphic lens within the bracket so that the shape of the image is the same at the top and bottom.

BASIC REQUIREMENTS

 The width of the projector beam should be less than three (3)

inches from where it enters the Optoma BX-AL133B anamorphic lens

 The recommended minimum throw distance from the

projector lens to the screen should be at least 12 feet

 The throw distance divided by the image width (“throw ratio”)

should be at least 1.6, prior to adding the Optoma BX-AL133B

 Before attaching the lens, the image must appear vertical

stretched; this can be done by selecting the “LBX” aspect ratio from the projector’s display menu

NOTES

 Any rotation of the lens around the vertical axis will

slightly shift the image in a horizontal direction

 To clean: Lightly blow off any surface debris from the

lens. If needed, clean the lens using standard camera cleaning supplies while the projector is on (be careful not to look directly into the light beam of the projector)
