NEC WT600 ... screen when you stand in front of it. This projector expands the opportunities for use and can be used by anyone, anywhere.

In an ordinary projector (lens-projection type projector) images are displayed using a projection lens, which consists of about 10 components. Using this method, shortening the throwing distance is technically limited by the lens diameter, curvature, and weight. The WT600 projector is equipped with NEC's unique optical design using aspheric mirrors. NEC achieved the super short focal distance, impossible in ordinary projectors, by introducing the aspheric mirror, which was developed and produced with super-high accuracy plastic mirror technology. The short throwing distance means the presenter can stand in front of the screen without blocking the light from the projector; so, there are no shadows on the screen. Presentations focus more on the presenter. By introducing a mechanism moving the mirror (electric powered), focus adjustment can be made for a variable screen size, and screen distortion (distortion aberration) is suppressed within practical levels. The "Pin cushion correction" function electrically corrects screen distortion.
