Abstract: Fabricating optical devices can include mounting a plurality of singulated lens systems over a substrate, adjusting a thickness of the substrate below at least some of the lens systems to provide respective focal length corrections for the lens systems, and subsequently separating the substrate into a plurality of optical modules, each of which includes one of the lens systems mounted over a portion of the substrate. Adjusting a thickness of the substrate can include, for example, micro-machining the substrate to form respective holes below at least some of the lens systems or adding one or more layers below at least some of the lens systems so as to correct for variations in the focal lengths of the lens systems.

Abstract: A flash module comprises an optics portion that includes a base plate, a light guide on a first side of the base plate, and a lens element on a second side of the base plate. A casing is attached to the optics portion and defines an interior region in which the lens element is located. An active light emitting component is mounted within the casing. Sidewalls of the light guide are coated with first and second layers of different materials. The second layer is a coating over the first layer and is substantially non-transparent to light emitted by the active light emitting component. The first layer can provide a predetermined aesthetic appearance and can be selected, for example, to match the color of the exterior surface of a device in which the flash module is to be integrated.

Abstract translation: 闪光模块包括光学部分，其包括基板，在基板的第一侧上的导光体和在基板的第二侧上的透镜元件。 壳体附接到光学部件并且限定透镜元件所在的内部区域。 主动发光部件安装在壳体内。 导光板的侧壁涂有第一层和第二层不同的材料。 第二层是在第一层上的涂层，并且对于由有源发光部件发射的光基本上不透明。 第一层可以提供预定的美学外观，并且可以选择，例如，以匹配闪光模块将被集成在其中的装置的外表面的颜色。
