D-13
Example of Primary Lens Calculation
If the projection distance (L) = 32 m, the screen width (W) = 16 m and the anamorphic
lens is not used:
32m
SCOPE projection =
16m÷1
= 2.0x
32m
VISTA (FLAT) projection =
16m×(2048÷1998)
= 1.95x
32m
HDTV projection =
16m×(2048÷1920)
= 1.88x
Therefore, "NC-60LS17Z", which satisfies the magnifications in all of the above projections,
is selected as the primary lens.
