Also known as divergent lens, negative lens, concave lens or dispersive lens. A lens that causes parallel light rays to spread out – hence diverge – away from the optical axis once exiting the lens. The lens surfaces may be plano-concave, double concave or concave-convex. The edge of a diverging lens is always thicker than the center. Parallel light rays entering a diverging lens tend to form virtual images of the object that light ray is originating from.

Photonic Component Manufacturing
Moving Toward Automation
A shift in assembly methods would help reduce costs and increase production in the optoelectronics manufacturing and packaging industries. Manufacturing the laser diode is complicated by the existence of multiple proprietary techniques and intellectual property barriers together with complex device physics and unique materials.
Process engineering, design for manufacturing, design for test, standardization, outsourcing and automation are common procedures in other high-technology...
