1-3. Selecting the lens unit
This section provides the guideline information on how to select a screen size, projector mounting position, and type
of lens units, which is appropriate for your presentation purposes. Many types of optical lens for the projector are
available for separate sale to support various projection range.
Note that all descriptions given in this manual assume that the angle of projection is zero degree. In case of projection
from an upper position or from the right or left, it is necessary to calculate the width for the minimum projected image
that is a little larger than the screen size.

height
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 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.)
NP-9LS20ZM1 lens throw distance (m) = H × 2.23 to H × 4.16 : 5.0 m (min.) to 46.1 m (max.)
NP-9LS40ZM1 lens throw distance (m) = H × 4.34 to H × 6.76 : 5.8 m (min.) to 74.7 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 6), 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).
