        The FOM alfaSC system was designed with a comprehensive user interface to allow for experimental freedom in formulation of coating recipes. Integration of primary coating elements. Allowing for high reproducibility between each coating run and high comparability between coated devices as well as optimal production batch quality. The Slot Die bridge is build with attention to precision mounting and easy positioning of Slot Die head over substrate mounts on a rigid and vibration damping base. The vacuum chuck travels on a precision rail system and in combination with the attention to detail this system provides a versatile and robust tool for upscaling. The FOM alfaSC system comes with a choice of manual or automatic positioning of the Slot Die and manual or the motorized programed height and side shift adjustment with resolution of 1µm. Coating speed between 0.05 to 5.0 m/min (step-less). Parallelism setting and Slot Die lip straightness <1% provides precise material deposition. Cross and along web positioning to <100µm. Slot Die height (the coating gap) allow repeatable mounting providing repeatable batch processing from day to day. Drying - Metapor (tm) Vacuum chuck with a size range of A4 and up. Flatness from better than 20µm. Heating to 150°C, uniform across surface to <1°C.

        The FOM alphaSC represents the ultimate combination of control, functionality, and versatility in thin film research and production. All elements of its hardware, software and premium features have been tailored to eliminate experimental error and increase usability with both flexible and rigid substrates. The FOM alphaSC delivers an uncompromising package, providing users with unmatched versatility and control of their lab-scale materials and coating processes.
