7-1. Throw distance and screen size
This projector can be used with 5 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). Request the dealer to attach or
detach the lens unit.

CAUTION
• The law requires that the lens hood be mounted when using the NP49ZL lens unit in the USA or China. Be sure
to ask your dealer to mount the lens hood (model NP01LH).
TIP:
• Calculation of the throw distance from the screen size
NP45ZL lens throw distance (m) = H × 0.9 to H × 1.2 : 40"/1.0 m (min.) to 307"/7.8 m (max.)
NP46ZL lens throw distance (m) = H × 1.2 to H × 1.6 : 52"/1.3 m (min.) to 397"/10.1 m (max.)
NP47ZL lens throw distance (m) = H × 1.5 to H × 2.0 : 63"/1.6 m (min.) to 507"/12.9 m (max.)
NP48ZL lens throw distance (m) = H × 2.0 to H × 4.0 : 87"/2.2 m (min.) to 1015"/25.8 m (max.)
NP49ZL lens throw distance (m) = H × 4.0 to H × 7.0 : 170"/4.3 m (min.) to 1779"/45.2 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 NP47ZL lens:
According to the “Screen Size (for reference)” table (
→
), H (screen width) = 84.8"/215.4 cm (approx. 2.15 m).
The throw distance is 84.8"/2.15 m × 1.5 to 84.8"/2.15 m × 2.0 = 127"/3.2 m to 170"/4.3 m (because of the zoom lens).
