Projection Distance And Lens Shift Range - Sony VPL-PHZ12 Operating Instructions Manual

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.
