摘要：
In an embodiment, there is provided a three-dimensional (3-D) optic for beam shaping. The 3-D optic includes a first surface, a second surface and a beam forming feature. The first surface is configured to receive incident light. The second surface is positioned relative to the first surface and is configured to emit a light beam having a shape. The emitted beam shape is related to the beam forming feature. The beam forming feature is formed by a 3-D manufacturing process.
