Notes
For a 5:4 full height image,
measuring 1313 x 1050 pixels:
A Throw ratio factor (TRF) of
1.07 would need to be applied
for the chart to be correct.
(ie: multiply the required screen
width by 1.07 before consulting
the chart)
The lenses available and their
part numbers are listed below:
0.73 : 1 fixed lens 105-607
1.2 : 1 (3 - 15m) fixed lens 105-608
1.5 - 2.02 : 1 zoom lens 105-610
2.02 - 2.77 : 1 zoom lens 105-611
2.77 - 4.51 : 1 zoom lens 105-612
4.51 - 7.53 : 1 zoom lens 105-613
