TIP:
• Calculation of the throw distance from the screen size
NP11FL lens throw distance (inch/m) = H × 0.8 : 27"/0.7 m (min.) to 101"/2.6 m (max.)
NP12ZL lens throw distance (inch/m) = H × 1.2 to H × 1.5 : 30"/0.7 m (min.) to 636"/16.1 m (max.)
NP13ZL lens throw distance (inch/m) = H × 1.5 to H × 3.0 : 38"/0.9 m (min.) to 1272"/32.3 m (max.)
NP14ZL lens throw distance (inch/m) = H × 2.9 to H × 4.7 : 147"/3.7 m (min.) to 1992"/50.6 m (max.)
NP15ZL lens throw distance (inch/m) = H × 4.6 to H × 7.1 : 234"/5.9 m (min.) to 3010"/76.4 m (max.)
NP40ZL lens throw distance (inch/m) = H × 0.8 to H × 1.1 : 33"/0.8 m (min.) to 466"/11.8 m (max.)
NP41ZL lens throw distance (inch/m) = H × 1.3 to H × 3.0 : 55"/1.4 m (min.) to 1272"/32.3 m (max.)
NP43ZL lens throw distance (inch/m) = H × 3.0 to H × 5.9 : 127"/3.2 m (min.) to 2501"/63.5 m (max.)
"H" (Horizontal) refers to the screen width.
* Figures differ by several % with the table above because the calculation is approximate.
Ex.: Throw distance when projecting on a 150" screen using the NP41ZL lens:
According to the " Screen Size (for reference)" table (→ page 174), H (screen width) = 127"/323.1 cm.
The throw distance is 127"/323.1 cm × 1.3 to 127"/323.1 cm × 3.0 = 165"/420.0 cm to 381"/969.3 cm (because of the zoom
lens).
