Projection Distance and Lens Shift Range
The projection distance refers to the distance between the front of the lens and the projected
surface.
The lens shift range represents the distance in percent (%) by which the lens can be shifted from
the center of the projected image. The lens shift range is regarded as 0% when the point
A
in
the illustration (point where a line drawn from the center of the lens and the projected image
cross at right angles) is aligned with the center of the projected image and full width or full
height of the projected image is regarded as 100%.
