The CP-A52 uses technology which includes a free-shaped surface lens and fre-shaped surface mirror, achieving projection on a large 80-inch screen from only 63cm (including the projector). This means that large image projection in limited spaces is possible. And, the shadow of the presenter or teacher is not cast on the screen, so the audience can concentrate on the images. Furthermore, presentations and lessons can be conducted without anyone being distracted by the projector's light source or hot exhaust air.
