For screen sizes between 30" and 500" not indicated on the above table, use formulas below.

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

STANDARD (H X 1.5) - (H X 2.0)

NP01FL (H X 0.8)

NP03ZL (H X 1.9) - (H X 3.1)

NP04ZL (H X 3.0) - (H X 4.8)

NP05ZL (H X 4.7) - (H X 7.2)

NP02ZL (H X 1.2) - (H X 1.5)

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".

NOTE: The values in the tables are design values and may vary.
