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.



  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



  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)
