PROCESS FOR OPTICALLY TRANSPARENT VIA FILLINGA method of forming a filled via with an optically transmissive material and a resulting product. The method comprises drilling a via in a panel and filling the via with an optically transmissive material. The method can also be used to create a light transmissive section of a housing. A light source directed to one side of the via is seen through the optically transmissive material so as to be visible to a viewer viewing a surface at the second side of the via.Fig 1
