Vidikron Vision 65 User Manual

If you are installing a CineWide-equipped projector, proceed as follows to install and adjust 
the anamorphic lens. 

Vidikron offers two types of anamorphic lenses for its CineWide projectors: prismatic

 and 

cylindrical.

• The prismatic lens compresses the height of the image (as opposed to stretching the 

width) to achieve a 2.35:1 aspect ratio with a 1.78:1 display device. 

• The cylindrical anamorphic lens has a larger aperture than the prismatic lens. It stretches 

the width of the image to achieve a 2.35:1 aspect ratio with a 1.78:1 display device. Two, 
cylindrical anamorphic lens options are available: Rainier II and McKinley. Although they 
differ in size and throw distance range (refer to Table 3-3), the installation procedure for 
both lenses is similar. 

The Vision 65/CineWide and Vision 75/CineWide are available with either a prismatic or a 
cylindrical anamorphic lens; the Vision 65/CineWide with AutoScope and Vision 75/CineWide 
with AutoScope always use a cylindrical lens. 

If you are installing a CineWide projector with a prismatic lens, refer to Whitney (Prismatic) 
Anamorphic Lens Installation and Adjustment on page 40. If you are installing a CineWide 
projector with a cylindrical lens, continue with the next section.
