Abstract
A method of forming a panel with an optically transmissive portion and resulting products. The method comprises drilling a via through a panel and filling the via with an optically transmissive material. A top surface and/or a bottom surface of the panel at the optically transmissive portion is smooth and continuous to the naked eye. 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.
