Lens Shift Range for Desktop and Ceiling Mount
Application
The diagram below shows the location of the image position
in the lens. The lens can be shifted within the shaded area as
shown using the normal projection position as a starting
point.
Note:
Lens shift feature is not available with GT10RL (rear
lens). GT10RL should be used only for “zero degree” / “no-
offset” applications.
Maximum Possible Range
for GT19ZL/GT24ZL/GT34ZL (GT13ZL):
Up: 0.5V (0.43V)
Down: 0.5V (0.43V)
Right: 0.25H
Left: 0.25H
(H: width of projected image, V: height of projected image)
Note:
If lens is shifted in two directions combined, maximum
range in either direction cannot be obtained due to rounded
off area near edge of lens. (example: shift up and right)
