An improved coating for optical fibers is described. The present invention is a dimensionally precise and uniform coating with low-porosity. The improved coating is applied via sputtering within a vacuum chamber. Environmental conditions are monitored within a cylindrical magnetron during sputtering. Sputtering is adjusted or temporarily ceased when environmental conditions approach a damage threshold. Sputtered particles within a plasma cloud are dimensionally similar and adhere to an optical fiber in a volume efficient arrangement forming a more precise, denser, and more adherent coating. Embodiments of the present invention provide improved pull strength by compressively constraining the optical fiber within the coating and by closing microcracks.

Coating for optical fibers and method therefor

A substrate is roboticaly picked up at a station and transported to a measuring station to measure the distance to a reference. The substrate is aligned to a robot before measurement. The measured substrate is then transported to a pharmaceutical or diagnostic powder/grain deposition station where the powder/grains are controllably deposited on the substrate to predetermined thicknesses over a plurality of powder/grain collection zones. The deposited powder/grains are then measured to determine the thickness and area covered by the deposited powder/grains at each collection zone. The substrate is then transported to a lamination station and each collection zone of powder/grains is welded to a cover substrate. The system remembers which collection zones are out of specification so that they can be later selectively discarded.
