Notes
The Throw ratio for a particular lens
is xed, but assumes that the image
lls the width of the DMD.
For images that do not ll the width
of the DMD, the throw ratio is
effectively increased. To correct for
this in these calculations, a throw
ratio factor (TRF) is used.
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.
