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, the following lens units, which satisfy the magnifications in all of the above projections, are selected.
Not using the lens memory function
NP-9LS16Z1
Using the lens memory function
NP-9LS13ZM1 or NP-9LS16ZM1
