ABSTRACT:
A lens for substantially collimating light in one axis and spreading light in an axis substantially perpendicular to the collimation axis including a lens an entry face which is positive and cylindrical, having a cross-section which includes the positive cylindrical curvature and having tapered sides substantially parallel to the refracted rays produced by the cylinders curvature and a circular convex or a spheric exit face perpendicular to the cylindrical curvature.
