Projection Distance and Lens Shift Range
The following describes the projection distance and height from lens center to bottom of screen
by each projected screen size.
The projection distance is the distance between the front of the lens and the surface of the
projected image.
Height H is the height from the bottom of the projected image (top for ceiling mount) to A
(determined by drawing a perpendicular line from lens center to projected image surface). For
this unit, the same projection distance calculations apply to both floor and ceiling installation.
