8. Using Optional Lenses
Five optional lenses are available for the NP3250/NP2250/NP1250/NP3250W. See the information described on
this page to buy the appropriate lens for your screen size and throw distance. See page
142 for installing the lens.

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 0.89 m to 20.83 m/35.1" to 820.2"
Throw distance for NP01FL(m/inch)=H × 0.8 Distance from 0.64m to 2.5 m/25.3" to 98.6"
Throw distance for NP02ZL(m/inch)=H × 1.2 through H × 1.5 Distance from 0.7 m to 16.1 m/27.5" to 634"
Throw distance for NP03ZL(m/inch)=H × 1.9 through H × 3.1 Distance from 1.56 m to 32.15 m/61.4" to 1265.6"
Throw distance for NP04ZL(m/inch)=H × 3.0 through H × 4.8 Distance from 3.6 m to 49.52 m/141.7" to 1949.5"
Throw distance for NP05ZL(m/inch)=H × 4.7 through H × 7.2 Distance from 5.69 m to 74.36 m/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 00" screen with the lens NP03ZL
Referring to the diagram on page
154 , “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.
