Throw distance and screen size
This projector can be used with 8 kinds of optional lenses (sold separately). Refer to the information on this page and
use a lens suited for the installation environment (screen size and throw distance). For instructions on mounting the
lens, see page
143 .

TIP
Calculation of the throw distance from the screen size
NP16FL lens throw distance (m) = H × 0.8 : 0.8 m (min.) to 5.1 m (max.)
NP17ZL lens throw distance (m) = H × 1.3 to H × 1.8 : 1.3 m (min.) to 11.7 m (max.)
NP18ZL lens throw distance (m) = H × 1.7 to H × 2.3 : 1.8 m (min.) to 14.9 m (max.)
NP19ZL lens throw distance (m) = H × 2.2 to H × 3.7 : 2.4 m (min.) to 24.1 m (max.)
NP20ZL lens throw distance (m) = H × 3.6 to H × 5.4 : 3.8 m (min.) to 35.4 m (max.)
NP21ZL lens throw distance (m) = H × 5.3 to H × 8.3 : 5.6 m (min.) to 54.8 m (max.)
NP31ZL lens throw distance (m) = H × 0.8 to H × 0.9: 0.6 m (min.) to 10.4 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 NP18ZL lens:
According to the “Screen Size (for reference)” table ( → page 163 ), H (screen width) = 127.2"/323.1 cm.
The throw distance is 323.1 cm × 1.7 to 323.1 cm × 2.3 = 549.3 cm to 743.13 cm (because of the zoom lens).
