Notes
  The throw ratios given here apply 
only when the image lls the width 
of the DMD.
  For images that do not ll the width 
of the DMD, the throw ratio needs to 
be recalculated using a throw ratio 
correction (TRC).
  For further information, see 
Choosing A Lens and Appendix B: 
Lens Charts in this guide.
  Throw distance calculations are 
based on the distance from the outer 
end of the lens, which will vary from 
lens to lens.
  The High Brightness lenses are 
recommended for the standard 
models, for maximum light output.
  The High Contrast lenses are 
recommended for the Ultra Contrast 
models, for maximum contrast.
  Lens extension is measured when 
the lens is focussed at innity, 
and fully extended. At other focus 
settings, the extension could be up 
to 10mm less.
