Installing and Adjusting the CineWide Anamorphic Lens

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

It is extremely important that the primary lens is properly adjusted

Note before you install the anamorphic lens. Ensure that the image from

the primary lens is perfectly centered on the screen.

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.
