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
157 .
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
NP25FL lens throw distance (m) = H × 0.67 : 1.1 m (min.) to 3.2 m (max.)
NP26ZL lens throw distance (m) = H × 1.35 to H × 1.84 : 2.8 m (min.) to 24.0 m (max.)
NP27ZL lens throw distance (m) = H × 1.84 to H × 2.54 : 4.0 m (min.) to 24.0 m (max.)
NP28ZL lens throw distance (m) = H × 2.62 to H × 4.20 : 9.0 m (min.) to 45.0 m (max.)
NP29ZL lens throw distance (m) = H × 4.21 to H × 6.96 : 12.0 m (min.) to 80.0 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 using the NP27ZL lens:
According to the “Screen Size (for reference)” table ( → page 211 ), H (screen width) = 323.1 cm.
The throw distance is 323.1 cm × 1.7 to 323.1 cm × 2.3 = 549.3 cm to 743.13 cm (because of the zoom lens).
• Using the NP28ZL lens will slightly change the image size. When using the NP28ZL lens to adjust the image size, adjust the focus
and then the zoom.
