The ultimate guide to 3D technologies Video Description

Second, it is hard to obtain a good collimation property in a wide view-angle with a single lens. This is why camera objectives and microscopes use lens compounds instead of single lens elements. Therefore lenticular systems are bound to have only a rather small field of view (about 20deg) where one can observe true motion parallax. Past that range, the 3D image repeats itself as if seen from the wrong angle, and becomes increasingly blurry.
