15/35600 - Draw tower for DTU Department of photonics engineering

DTU Department of Photonics Engineering wishes to purchase an optical fiber draw tower to be used for the drawing of microstructured optical fibers (MOFs) with complicated structures of micron sized air holes. In particular it should be used to draw so-called chalcogenide glass MOFs that contain Arsenic, Selenide and Sulfide elements. The draw tower should both be able to draw up to 50 mm in diameter preforms down to mm-sized canes using a so-called cane-puller and it should be able to draw canes down to micron sized fibers and spool these on standard fiber spools. To make several independently controlled air hole- sections in the MOF the draw tower should be able to place parts of the preform and cane under vacuum and several parts under different pressures. As a minimum vacuum and 4 independent pressure systems should be available. The draw tower should be 6m high excluding preform feeder and be equipped with a single layer coating system.
