Good Day All.

i have a client who wants to use an older Projector. The old throw was ~20ft and the new is 30ft .

the model is not on any of the current Projector Calculators.

NEC NC1000c
Lens NP-9LS13ZM1 1.33 to 2.1 Zoom lens
F=20.7-32.7mm/F2.5

Distance = Throw Ratio x Image Width.
360" = x * 130"
360" = 2.77 * 130"

this lens will not go to 2.77 there for the Projector will not work.
Is this Correct?




Thanks,
Flandon
