Eiki Wide Power Zoom Lens

The Eiki AH-EC21020 is a wide-angle powered zoom lens for Eiki's EK-850LU and EK-1000LU 3LCD laser projectors, a dealer-installed option chosen to match short throw distances in tighter rooms. Its 2.35x zoom range and f/1.7 to f/2.0 aperture let an installer fill a screen from close in while holding brightness across the frame.

Both zoom and focus are motorized, so throw and sharpness can be set from the projector's remote or control system rather than at the lens, which matters for a unit rigged high in a ceiling or truss. The lens mounts into the projector's interchangeable bayonet, letting one chassis be re-optiked as a room's requirements change.
