Profile: Potomac Photonics, manufactures waveguide Excimer laser. We also provide microfabrication of miniaturized products, milling and filling. We provide microfabrication in most materials such as polymers, metals, ceramics and glass. Filling is used to reflect additive processing. It includes transfer and mill&fill laser based manufacturing methodologies. With contact transfer, we utilize laser light to transfer material from a carrier ribbon onto the component. This process is capable of directly writing a variety of materials including conductors, resistors and insulators.
