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