Lens Shift Adjustable Range The top right diagram 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. Maximum Possible Range for GT20ZL lens: Up: 0.64V (V: height of projected image) Down: 0.64V Right: 0.33H (H: width of projected image) Left: 0.33H Note: Check availability of GT19ZL. (GT10RL is discontinued) Note: Lens shift is not available on the GT10RL/GT10RLB rear lenses. GT10RL/GT10RLB should be used only for "zero degree/no-offset" applications. Note: If the lens is shifted in two directions combined, maximum range in either direction cannot be obtained due to rounded off area of lens. (example: shift up and right) See top right diagram. 0.33H 1H 0.33H Desktop/Front Vertical Normal position Ceiling/Front Vertical Normal position 0.64V V Normal projection position 0.33H V 0.64V 1V 0.64V H 0.33H www.necvisualsystems.com 0.64V Normal position Horizontal GT1150/2150 Page 4 of 10
