Appendix; ❶ Throw Distance And Screen Size; Lens Types And Throw Distance - NEC NP-PA703UL User Manual

8. Appendix

❶ Throw distance and screen size
Three 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 138.

TIP
Calculation of the throw distance from the screen size
NP40ZL lens throw distance (inch/m) = H x 0.8 to H x 1.1 : 33"/0.8 m (min.) to 478"/12.1 m (max.)
NP41ZL lens throw distance (inch/m) = H x 1.3 to H x 3.0 : 54"/1.4 m (min.) to 1285"/32.6 m (max.)
NP43ZL lens throw distance (inch/m) = H x 2.9 to H x 5.7 : 129"/3.3 m (min.) to 2497"/63.4 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 NP41ZL lens:
According to the "Screen Size (for reference)" table (→ page 153), H (screen width) = 127.2"/323.1 cm.
The throw distance is 127.2"/323.1 cm × 1.3 to 127.2"/323.1 cm × 3.0 = 165"/420.0 cm to 382"/969.3 cm (because of the zoom lens).
