Inrad Optics, Inc. (INRD) has advanced its thin film coating capabilities with the installation of a new plasma assisted e-beam vacuum deposition system. The new coating system employs high-density plasma technology to dramatically enhance the quality of thin films by improving a wide variety of mechanical and optical properties. Its large 96-inch chamber also significantly increases Inrad Optics' capacity and allows the company to handle parts up to 1 meter in diameter.

George Murray
, Vice-President of Sales and Marketing, Inrad Optics, reports, "This new plasma assisted coatings system represents a significant step up for Inrad Optics coatings services. It will eliminate production bottlenecks to dramatically improve lead-times, while improving our process control. Access to this level of technology in-house rounds out our turnkey custom optics services and is a springboard for delivering some of the industry's most advanced coatings services."

Plasma assisted deposition represents an evolution of the ion assisted e-beam process that Inrad Optics has successfully employed for years. Like ion assist, the new plasma-based deposition process relies on electron beams to evaporate coating materials prior to deposition on a substrate. Unlike its predecessor, however, plasma assist combines reactive ions and evaporated coating materials within high-density DC plasma. The resulting thin films are of a measurably higher quality than previous processes.

Amy Eskilson, President and CEO, Inrad Optics, adds, "This significant investment in state-of-the-art coating technology not only serves to meet Inrad Optics' internal needs, but also enables us to offer superior contract thin film coating services. This advancement is a clear signal of our commitment to investing in the people and technology required to deliver the highest level of service and expertise to our customers."
