9. Appendix Lens types and throw distance unit = m [PX750U] Screen size 50" 60" 80" 100" 120" 150" 200" 240" 300" NP16FL 0.8 1.0 1.3 1.7 2.0 2.5 3.4 4.1 5.1 NP17ZL 1.3 - 1.9 1.6 - 2.3 2.2 - 3.1 2.7 - 3.9 3.3 - 4.7 4.1 - 5.8 5.5 - 7.8 6.6 - 9.4 8.2 - 11.7 Lens model name NP18ZL NP19ZL 1.8 - 2.4 2.4 - 4.0 2.2 - 2.9 2.8 - 4.8 3.0 - 3.9 3.8 - 6.4 3.7 - 4.9 4.8 - 8.0 4.5 - 5.9 5.8 - 9.6 5.6 - 7.4 7.2 - 12.0 7.5 - 9.9 9.7 - 16.1 9.1 - 11.9 11.6 - 19.3 11.3 - 14.9 14.5 - 24.1 NP20ZL 3.8 - 5.8 4.6 - 7.0 6.2 - 9.3 7.7 - 11.7 9.3 - 14.1 11.7 - 17.6 15.6 - 23.5 18.8 - 28.3 23.5 - 35.4 NP21ZL 5.6 - 8.9 6.8 - 10.7 9.1 - 14.4 11.5 - 18.1 13.8 - 21.7 17.4 - 27.3 23.3 - 36.4 28.0 - 43.8 35.0 - 54.8 TIP Calculation of the throw distance from the screen size NP16FL lens throw distance (m) = H × 0.8 : 0.8 m (min.) to 5.1 m (max.) NP17ZL lens throw distance (m) = H × 1.3 to H × 1.8 : 1.3 m (min.) to 11.7 m (max.) NP18ZL lens throw distance (m) = H × 1.7 to H × 2.3 : 1.8 m (min.) to 14.9 m (max.) NP19ZL lens throw distance (m) = H × 2.2 to H × 3.7 : 2.4 m (min.) to 24.1 m (max.) NP20ZL lens throw distance (m) = H × 3.6 to H × 5.4 : 3.8 m (min.) to 35.4 m (max.) NP21ZL lens throw distance (m) = H × 5.3 to H × 8.3 : 5.6 m (min.) to 54.8 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 using the PX750U to project on a 150" screen using the NP18ZL lens: According to the "Screen Size (for reference)" table (→ page 204), 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). Projection range for the different lenses [PX750U] NP16FL : 0.8-5.1m 50-300" 50-300" 50-300" NP17ZL : 1.3-11.7m NP18ZL : 1.8-14.9m NP19ZL : 2.4-24.1m 50-300" 50-300" 50-300" NP20ZL : 3.8-35.4m NP21ZL : 5.6-54.8 m 205
