Throw Ratio - CL-810 Ultra: Table 3-3 lists the available lens options for the
CL-810 Ultra and their associated throw ratios.
Throw Ratio - CL-810: The CL-810 offers a throw ratio of between 1.80 and 2.43.
Throw Ratio - CL-810 CineWide: The CineWide version of the CL-810 also offers a
throw ratio of between 1.80 and 2.43. It uses a prismatic-style anamorphic lens that
compresses the image height (as opposed to the cylindrical anamorphic lenses used with
the CL-810 Ultra, which stretch the image width). Using this lens type does not change
the projector throw ratio.

Notes:
1. Throw distance does not affect image quality, provided these ranges are taken into account.
2. Only the Proteus D, E and F lenses can be used with the optional CineWide (secondary
anamorphic) lens. Doing so affects the throw distances as shown here.
