TIP
Calculation of the throw distance from the screen size
NP11FL lens throw distance (m) = H × 0.8 : 0.6 m (min.) to 2.5 m (max.)
NP30ZL lens throw distance (m) = H × 0.8 to H × 1.1 : 1.0 m (min.) to 10.9 m (max.)
NP12ZL lens throw distance (m) = H × 1.2 to H × 1.6 : 0.7 m (min.) to 16.0 m (max.)
NP13ZL lens throw distance (m) = H × 1.5 to H × 3.0 : 1.2 m (min.) to 30.8 m (max.)
NP14ZL lens throw distance (m) = H × 3.0 to H × 4.8 : 3.6 m (min.) to 49.2 m (max.)
NP15ZL lens throw distance (m) = H × 4.7 to H × 7.3 : 5.7 m (min.) to 73.8 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 with the PA722X/PA622X using the NP13ZL lens:
According to the “Screen Size (for reference)” table (
→
page
161
), H (screen width) = 304.8 cm.
The throw distance is 304.8 cm × 1.5 to 304.8 cm × 3.0 = 457.2 cm to 914.4 cm (because of the zoom lens).
