Abstract
A compound lens and a related method of manufacture are provided. The compound lens includes a first lens element and a second lens element such that a light emitting surface of the first lens element is integrally joined to a light receiving surface of the second lens element, the first and second lens element being in optical alignment with each other. The first and second lens element are molded from optical grade silicone and can achieve complex illumination objectives not possible with single lens constructions. The method of manufacture includes injecting a silicone resin molding compound into a mold cavity having the desired shape of the compound lens. The method of manufacture can include over-molding a lens holding member onto the compound lens and adding electro-optically active particles to a surface of the compound lens or to the silicone resin forming the compound lens.
