Throw distance and screen size
Four 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 installation and replacement of lens
units contact your dealer.
Each number provided in the table below means the throw distance between the lens surface and the screen.

TIP
• Calculation of the throw distance from the screen size
NP-9LS08ZM1 lens throw distance (m) = H × 0.90 to H × 1.35 : 1.4 m (min.) to 18.1 m (max.)
NP-9LS12ZM1 lens throw distance (m) = H × 1.28 to H × 1.83 : 2.8 m (min.) to 20.2 m (max.)
NP-9LS13ZM1 lens throw distance (m) = H × 1.42 to H × 2.24 : 3.1 m (min.) to 24.8 m (max.)
NP-9LS16ZM1 lens throw distance (m) = H × 1.73 to H × 2.88 : 3.8 m (min.) to 31.9 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 300" screen using the NP-9LS13ZM1 lens:
According to the “Tables of screen sizes and dimensions” (
→
page
), H (screen width) = 664.1 cm.
The throw distance is 6.641 cm × 1.42 to 6.641 cm × 2.24 = 9.430 cm to 14.876 cm (because of the zoom lens).
