❶ 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 instructions on mounting the lens, see page 153.

TIP
Calculation of the throw distance from the screen size
Replacement Lens Type1 lens throw distance (m) = H × 0.8 : 0.7 m (min.) to 2.6 m (max.)
Replacement Lens Type8 lens throw distance (m) = H × 0.8 to H × 1.0 : 1.0 m (min.) to 11.3 m (max.)
Replacement Lens Type2 lens throw distance (m) = H × 1.2 to H × 1.5 : 0.7 m (min.) to 16.5 m (max.)
Standard Lens Type1 lens throw distance (m) = H × 1.5 to H × 3.0 : 1.2 m (min.) to 31.9 m (max.)
Replacement Lens Type3 lens throw distance (m) = H × 2.9 to H × 4.7 : 3.7 m (min.) to 50.9 m (max.)
Replacement Lens Type4 tlens hrow distance (m) = H × 4.6 to H × 7.1 : 5.9 m (min.) to 76.4 m (max.)
“H” (Horizontal) refers to the screen width.
* Figures dier by several % with the table above because the calculation is approximate.
Ex.: Throw distance when projecting on a 150" screen with the WUXGA Type using the Standard Lens Type1:
According to the “Screen Size (for reference)” table (→ page 234), H (screen width) = 323.1 cm.
The throw distance is 323.1 cm × 1.5 to 323.1 cm × 3.0 = 484.7 cm to 969.3 cm (because of the zoom lens).
