USI PRISM Platform Applies Anti-Reflective Coatings That Help Lenses and Panels Achieve Optimal Clarity

by | Jan 16, 2018 | Press Releases

Haverhill, MA – Ultrasonic Systems, Inc. (USI), a leader in ultrasonic spray coating systems, sets a higher standard in producing uniform coatings that support superior optical performance in lenses and glass panels. Anti-reflection (AR) coatings improve the efficiency of lenses used for LED lighting and traffic lights, as well as glass plates and glass panels used in the solar and smart device markets. The uniformity of the applied coating layer is critical to performance, as measured by both optical transmission and reflection.
USI’s tCAT technology applies a single, uniform layer with a dry layer thickness in the range of 100 nm to 150 nm. USI’s technology is also used to apply nano particle coatings in a uniform and defect-free layer that ensures top optical performance.

The full range of substrate types for thin film coatings include glass plates, lenses, plastic substrates, wafers, and flexible films. USI’s PRISM 1200 and PRISM 800 systems employ a proprietary reciprocating head motion profile to deliver an ultra-uniform coating layer to substrates up to 1,200 mm wide.

USI’s ultrasonic spray head is a solid-state device with no moving parts. It atomizes the coating liquid using ultrasonic energy and then shapes the spray into a flat, sheet-like pattern using low pressure air flow. The spray head is “cleaned in place.” No intricate adjustments are required for setup and no disassembly is required for cleaning.

USI’s advanced liquid delivery system controls flow rate using a precision metering pump (PMP) that is fully integrated into the control system. The liquid flow rate is set in the coating recipe in increments of 1/10th of 1 ml/min.

“USI systems meet the demand for thin, uniform thickness down to sub-micron level required by manufacturers,” said Chris Lasonde, Applications Engineer at USI. “Process repeatability is another area in which USI products lead the industry.”

USI Expands Installed Base of Precision Coating Technology at Fuel Cell Companies in Asia

by | Jan 16, 2018 | Press Releases

Haverhill, MA – Ultrasonic Systems, Inc. (USI), a leader in ultrasonic spray coating systems, announced it has expanded its installed base of fuel cell coating systems in Asia. Companies in Shanghai, Chengdu, and Shenzhen, China, as well as Hyderabad, India have recently implemented USI’s PRISM systems for their fuel cell manufacturing processes.

USI products deliver superior performance in coating deposition for fuel cell manufacturing, with an advanced technology that provides precise control of coating pattern and film thickness. Numerous coatings are used in the construction of fuel cells, many of which are precious metal or ceramic based slurries containing suspended particles. The ability to apply these coatings uniformly and keep the suspended particles properly mixed during the coating process is critical to the quality and performance of the fuel cell.

USI’s automated method for the precise application of fuel cell coating materials utilizes USI’s proprietary ultra-Thin Coating Application Technology (tCAT), combining ultrasonic “nozzle-less” spray with a high-performance programmable motion and control platform with advanced material handling capabilities. Ultrasonic energy breaks liquids into small drops to form the spray and directed air streams are used to shape the ultrasonically produced spray, providing a rectangular, uniform spray pattern. USI’s advanced liquid delivery components ensure the coating liquid properties remain consistent during the coating process.

“USI systems meet the demand for thin, uniform thickness down to sub-micron level required by modern fuel cell manufacturers,” said Larry Sirois, Senior Applications Engineer for USI. “Process repeatability is another area where USI products lead the industry.”

USI offers a full line of coating systems for fuel cell coating from the PRISM-400 for lab-scale and R&D applications to the PRISIM-800 for high-volume production and large size substrates.
