What determines a projectors throw distance? I am assuming it is the lens, but are there other factors?


If we wanted to achieve a longer throw from say an LT-150, would it "simply" (ha!) be a matter of replacing the lens assembly with one that has a longer throw?


Can anyone point me to a sort of "Optics For Dummies"?


TIA

To sum up: throw ratio is determined by focal length of the lens in ratio to the diagonal size of the LCD or DLP. So to achieve a longer throw ratio for a given projector, you would choose a lens with a longer focal length.
