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 133.

TIP:
Calculation of the throw distance from the screen size
NP16FL-4K lens throw distance (m) = H × 0.76 : 32"/0.8 m (min.) to 205"/5.2 m (max.)
NP17ZL-4K lens throw distance (m) = H × 1.24 to H × 1.78 : 53"/1.4 m (min.) to 470"/11.9 m (max.)
NP18ZL-4K lens throw distance (m) = H × 1.71 to H × 2.25 : 73"/1.9 m (min.) to 596"/15.1 m (max.)
NP19ZL-4K lens throw distance (m) = H × 2.20 to H × 3.67 : 95"/2.4 m (min.) to 968"/24.6 m (max.)
NP20ZL-4K lens throw distance (m) = H × 3.54 to H × 5.36 : 152"/3.9 m (min.) to 1416"/36.0 m (max.)
NP21ZL-4K lens throw distance (m) = H × 5.25 to H × 8.28 : 224"/5.7 m (min.) to 2195"/55.7 m (max.)
NP31ZL-4K lens throw distance (m) = H × 0.74 to H × 0.93 : 32"/0.8 m (min.) to 248"/6.3 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 100" screen using the NP18ZL-4K lens:
According to the "Screen Size (for reference)" table (→ page 145), H (screen width) = 87.1"/221.3 cm (approx. 2.21 m).
The throw distance is 87.1"/2.21 m × 1.71 to 87.1"/2.21 m × 2.25 = 149"/3.8 m to 196"/5.0 m (because of the zoom lens).
