TIP
Calculation of the throw distance from the screen size
NP11FL lens throw distance (inch/m) = H × 0.8 : 26"/0.7 m (min.) to 101"/2.6 m (max.)
NP30ZL lens throw distance (inch/m) = H × 0.8 to H × 1.0 : 33"/0.8 m (min.) to 445"/11.3 m (max.)
NP12ZL lens throw distance (inch/m) = H × 1.2 to H × 1.5 : 28"/0.7 m (min.) to 651"/16.5 m (max.)
NP13ZL lens throw distance (inch/m) = H × 1.5 to H × 3.0 : 36"/0.9 m (min.) to 1257"/31.9 m (max.)
NP14ZL lens throw distance (inch/m) = H × 2.9 to H × 4.7 : 146"/3.7 m (min.) to 2004"/50.9 m (max.)
NP40ZL lens throw distance (inch/m) = H × 0.8 to H × 1.1 : 33"/0.8 m (min.) to 478"/12.1 m (max.)
NP41ZL lens throw distance (inch/m) = H × 1.3 to H × 3.0 : 54"/1.4 m (min.) to 1285"/32.6 m (max.)
NP43ZL lens throw distance (inch/m) = H × 3.0 to H × 5.9 : 129"/3.3 m (min.) to 2497"/63.4 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 NP13ZL lens:
According to the “Screen Size (for reference)” table ( → page 166 ), H (screen width) = 127"/323.1 cm.
The throw distance is 127"/323.1 cm × 1.5 to 127"/323.1 cm × 3.0 = 191"/484.7 cm to 381"/969.3 cm (because of the zoom lens).
