The unique short throw distance of the PLC-XL50 allows projection in virtually any environment, particularly areas that traditional projectors can not be used, such as floors and desktops.
In order for SANYO to shorten the projection distance of the PLC-XL50, new large diameter aspheric (non-spherical) lens and high-precision aspheric mirror technology were developed. A new optical engine was also developed, which enables an 80-inch projection from the short distance of about 3-inches (8 cm). This creates an opportunity to project extremely large images in any room or space that is available.
The proprietary optical and cooling mechanism technology used in the PLC-XL50 allows both vertical and horizontal projection. The new optical engine was created with a high-precision aspheric mirror combined with a distortion correction mechanism lens, enabling large magnification without distortion, even from ultra-short distances. To allow projection either vertically or horizontally, a special cooling mechanism was also essential. The resulting solution is a one-way flow system consisting of an air intake and exhaust mechanism on the main body of the projector -- thus allowing optimal positioning of the main components.
By shortening the distance for projection, the options for installation are greatly improved, which includes floor, tabletop and wall mount projection. The variety of applications is almost limitless, providing effective, quick and easy presentations or announcements.
Projecting a large screen on the floor in a pre-school creates a new style of teaching and classroom interaction.
- When installing the projector directly above the screen or blackboard in classroom, the light that once entered the teachers' eyes and long shadows are a thing of the past.
- Used as a tabletop projector, images can be projected on a dark surface allowing designers and architects to see their designs more visually for review or additional inspiration.
- The projector can be used in department stores to advertise sale products in hallways or on open floor spaces, optimizing the use of all available space.
- It is still possible to project large images when placing the projector directly next to a wall in a small office or meeting room.
- The projector can be used to make announcements on the ceiling, wall or floor at the entrance of a business or in a lobby.
Additional features include Top and Bottom Keystone Correction for proper alignment of the projector, a Color Board Mode, which allows adjustment of the hue when projecting an image on a colored (non-white) surface so that it appears to be projected on a white surface. The additional Black Board Mode enables educational institutions to use the projector with all standardized educational boards.
The PLC-XL50 has been outfitted with a built-in vibration sensor alert. An alarm sounds when the unit is picked up, proving to be an effective theft-deterrent. The unit turns on automatically when the power cord is plugged into an electrical outlet and with the Easy-Off function it's possible to remove the power cord without waiting for the machine to cool down, which is convenient for quickly clearing away the area after a presentation.
