3.2.2 Lens selection
How to select the right lens for your application
1. Determine the required screen width (SW).
2. Determine the 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 SW.
Tip: Divide PD by SW to determine the approximate throw ratio. Choose a Lens, which captures the calculated throw ratio.
Use the lens formula of the chosen Lens to recalculate exactly.
