Currently ASA is producing optics in Freistadt and the ASA CEO has also bought the Ifaso GmbH in Teisnach. These 2 production locations complete each other perfectly as Freistadt has a horizontal test setup and Ifaso a vertical test tower. In Teisnach, we have also access to other facilities as Ion Beam Polishing.
