❶ Throw distance and screen size
This projector can be used with 3 kinds of optional lenses (sold separately). The chart below shows compatible lenses
according to the projector model. Refer to the information on this page and use a lens suited for the installation envi-
ronment (screen size and throw distance). For instructions on mounting the lens, see page 121.

TIP
Calculation of the throw distance from the screen size
NP34ZL lens throw distance (inch/m) = H × 0.96 to H × 1.23 : 40"/1.0 m (min.) to 314"/7.9 m (max.)
NP35ZL lens throw distance (inch/m) = H × 1.23 to H × 1.54 : 51"/1.3 m (min.) to 392"/10.0 m (max.)
NP37ZL lens throw distance (inch/m) = H × 1.53 to H × 2.94 : 63"/1.6 m (min.) to 748"/19.0 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 PX602UL-WH/PX602UL-BK using the NP35ZL lens:
According to the "Screen Size (for reference)" table (→ page 155), H (screen width) = 127.2"/323.1 cm.
The throw distance is 127.2"/323.1 cm × 1.23 to 127.2"/323.1 cm × 1.54 = 156.5"/397.4 cm to 195.9"/497.6 cm (because of the
zoom lens).
