World Leader in High Performance, Durable Optical Thin-Film Coatings
Deposition Sciences, Inc. (DSI
®) produces a wide variety of highly reliable, durable, and heat-resistant optical coatings. Our exclusive technologies and customer deposition chambers offer coatings in the visible (VIS) near-infrared (NIR), shortwave infrared (SWIR), midwave infrared (MWIR), and longwave infrared (LWIR) spectral wavelengths.
Since 1985, DSI has provided optical coating solutions for military and defense, aerospace, security and surveillance, biomedical, scientific, and telecommunications applications. With collaborative product development, we deliver unique thin-film deposition technology, proprietary coating processes, and engineering excellence for real-world challenges. DSI's custom-built coating chambers, along with three coating deposition technologies and patented processes provide robust, reliable, and highly durable optical coatings on a wide variety of substrates, shapes, and sizes.
Specialized Coating Processes
DSI offers three coating technologies that accommodate the varied and often rigorous demands placed on thin film coatings. This comprehensive toolbox gives us the ability to provide unique solutions, higher performance, increased volume, and more durability in our coatings.
MicroDyn® Reactive Sputtering
The MicroDyn
® process is a short-throw reactive sputtering process. Highly flexible with the capability to deposit metals, metal oxides, nitrides, missed materials with fixed or graded compositions, ITO and semiconductor materials. MicroDyn coatings, including complex filters can be patterned using both contact masking and photolithography.
IsoDyn Low Pressure Chemical Vapor Deposition (LPCVD)
The LPCVD process is a thermally driven organo-metallic process that is configured to deposit multilayers of silicon dioxide, tantalum oxide, and titanium dioxide. LPCVD is a high-temperature process (-500 ºC) that provides extremely conformal and seamless coatings on a wide variety of substrates including glass, ceramics, and metals. The unique aspect of the LPCVD process is its capability to uniformly coat all surfaces, even the most complex shapes with high quality multilayer optical coatings.
Evaporative Coating
DSI's evaporative coating chambers are used for complex infrared coatings. Coatings can be laser and nuclear hardened, have minimum scatter and absorption, are space-qualified and meet all applicable military specifications. Infrared coatings with spectral performance requirements out to 25 µm in wavelength can be produced.
