CREWE, England, Aug. 30, 2012 — PV Precision, an optical coating system manufactured by Power Vision Ltd., coats small batches of substrates with fast cycle times.
The standard substrate carrier has six positions for mounting substrates in a vertical configuration. Special substrate tooling can be provided to maximize coating throughput and accommodate specific component types. The system incorporates a vacuum load lock for high throughput and low maintenance while maintaining vacuum conditions suitable for precise and high-quality deposition. Time to deposit a typical nine-layer broadband antireflection coating is ~20 min.
The system coats six substrates up to 100 mm2. It uses a patented magnetron sputtering process to deposit coatings with high density, adhesion and refractive index. The standard system is equipped with two target materials with the option for a three-material configuration. It uses an optimized plasma source to provide good in situ plasma cleaning while providing in-process ion bombardment.
The standard system’s low-temperature process coats temperature-sensitive materials including CR39, polycarbonate and polyethylene terephthlate. This process also is suited to producing low-stress coatings on a number of conventional substrates, including glass, silicon and metals.
An optional substrate heater enables high-temperature deposition up to 500 °C, and a meissner trap is available for vapor-critical processes. Applications include antireflection coatings, transparent conducting oxides, color/IR filters, visible and thermal control coatings, and thin films for photovoltaic applications.
