Throw distance and screen size
Six 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

TIP
Calculation of the throw distance from the screen size
NP11FL lens throw distance (m) = H × 0.8 : 0.7 m (min.) to 2.6 m (max.)
NP30ZL lens throw distance (m) = H × 0.8 to H × 1.0 : 1.0 m (min.) to 11.3 m (max.)
NP12ZL lens throw distance (m) = H × 1.2 to H × 1.5 : 0.7 m (min.) to 16.5 m (max.)
NP13ZL lens throw distance (m) = H × 1.5 to H × 3.0 : 1.2 m (min.) to 31.9 m (max.)
NP14ZL lens throw distance (m) = H × 2.9 to H × 4.7 : 3.7 m (min.) to 50.9 m (max.)
NP15ZL lens throw distance (m) = H × 4.6 to H × 7.1 : 5.9 m (min.) to 76.4 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 with the WUXGA Type using the NP13ZL lens:
According to the “Screen Size (for reference)” table ( → page 256 ), H (screen width) = 323.1 cm.
The throw distance is 323.1 cm × 1.5 to 323.1 cm × 3.0 = 484.7 cm to 969.3 cm (because of the zoom lens).
