 Throw distance and screen size

Five separate bayonet style lenses can be used on this projector. 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 141.

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.)
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 PA600X/PA500X using the NP13ZL lens:
According to the "Screen Size (for reference)" table (→ page 204), 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).
