The RICOH High-End Laser Projector series is made up of three installation-friendly models, the PJ WUL6670, PJ WUL6680, and PJ WUL6690. Suitable for large conference rooms and large venues with a projection area of up to 300 inches, dual units of this series can be combined without any additional equipment to cover even larger areas with image correction technology. They feature a large, motorized, horizontal, and vertical lens shift, making it easy to adjust the screen position regardless of the installation location.
