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 differ 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).
