In accordance with the teachings of the present invention, an optoelectronic system is provided for surface digitization of an object using spatiochromatic triangulation. The feedthrough is structured to maintain isolation of components in the IC from mechanical damage and chemical impurities introduced during fabrication and assembly operations. The coating stage comprise a coating material feeder and a coating device. At least one outer seal is compressed within its memory which allows for rotation of pipe andor sliding ring relative to the apparatus about the axis of the pipe. The union all operator references the data object.
