8. Appendix
❶ 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).
