Lenses
Which Lens has to be selected.
1 Determine the required screen width.
2 Determine the approximate position of the projector in the projection room with regard to the screen and measure the
projector-screen distance (PD).
3 Use the lens formulas to find the best corresponding PD with regard to the measured projector-screen distance for the required
screen width.
The desired lens is determined (the order number is given in the tabel).
