Throw distance for Standard lens (m/inch)=H × 1.5 through H × 2.0 Distance from 0.89m to 20.83m/35.1" to 820.2" Throw distance for NP01FL(m/inch)=H × 0.8 Distance from 0.64m to 2.5m/25.3" to 98.6" Throw distance for NP02ZL(m/inch)=H × 1.2 through H × 1.5 Distance from 0.7m to 16.1m/27.5" to 634" Throw distance for NP03ZL(m/inch)=H × 1.9 through H × 3.1 Distance from 1.56m to 32.15m/61.4" to 1265.6" Throw distance for NP04ZL(m/inch)=H × 3.0 through H × 4.8 Distance from 3.6m to 49.52m/141.7" to 1949.5" Throw distance for NP05ZL(m/inch)=H × 4.7 through H × 7.2 Distance from 5.69m to 74.36m/224.1" to 2927.5" "H"= Screen width NP04ZL (H X 3.0) - (H X 4.8) STANDARD (H X 1.5) - (H X 2.0) NP01FL (H X 0.8) NP02ZL (H X 1.2) - (H X 1.5) NP03ZL (H X 1.9) - (H X 3.1) NP05ZL (H X 4.7) - (H X 7.2) Example: Distance from a 100" screen with the lens NP03ZL Referring to the diagram on page 145, "H" is 2.0 m/78.7". Therefore, the projection distances of 100 inches are from 2.0 m/78.7" × 1.9 to 2.0 m/78.7" × 3.1 = from 3.8 m/150" to 6.2 m/244". 130
