Examples of selecting the lens unit
If the “projection distance (L) = 30 m, the screen width (W) = 15 m”:
SCOPE projection
=
30m
= 2.0x
15m
VISTA (FLAT) projection
=
30m
= 1.95x
15m×(2048÷1998)
HDTV projection
=
30m
= 1.88x
15m×(2048÷1920)
Therefore, “NP-9LS16Z”, which satisfies the magnifications in all of the above projections, is selected as the primary lens.
