8. Using Optional Lenses

Five optional lenses are available for the NP3150/NP2150/NP1150. See the information described on this page to buy the appropriate lens for your screen size and throw distance. See page 123 for installing the lens.

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 134, “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: Distances may vary +/-5%
