How to Calculate the Magnification of Primary Lens
SCOPE projection:
Length of projection (L)
Primary lens
magnification =
Screen width (W) ÷Anamorphic lens magnification
Use 1x for anamorphic lens magnification if this lens is not in use.
VISTA(FLAT)/HDTV projection:
Length of projection (L)
Primary lens
magnification =
Screen width (W) × (2048 ÷ Number of pixels per horizontal line)
* Number of pixels per horizontal line: 1998 for VISTA(FLAT); 1920 for HDTV
* Select a lens that meets the magnification requirement for both SCOPE and
VISTA(FLAT)/HDTV screen types.
