Optical circuit board assemblies having one or more lens bodies are disclosed. In one embodiment, the assembly comprises a composite circuit board comprising a glass-substrate and a non-glass substrate with the non-glass substrate having at least one cutout that exposes a portion of the glass substrate and at least one optical trace comprising one or more optical interfaces on the composite circuit board. The one or more optical interfaces of the composite circuit board are in optical communication with the one or more lens bodies. Other optical circuit board assemblies may include other features such as a bezel mount attached to the composite circuit board or an attachment structure secured to the composite circuit board.
