Rugate Technologies, Inc., founded in 1996, specializes in the R&D of high performance optical coatings and thin film devices. We work with our customers to develop designs and manufacturing processes for their specific applications and will then move the product into production here and/or transfer the process into the customer's facility.
Rugate Technologies expertise has been demonstrated in the fabrication of spectral control filters for higher efficiency thermophotovoltaic (TPV) devices, narrow notch infrared filters with broad field of view, and dual band infrared coatings.
Rugate Technologies is under contract with the U.S. Army to develop dual-band (MWIR and LWIR) antireflection coatings (ARs), fold mirrors, beamsplitters, and cold filters for use in FLIR imagers. Substantial improvement in dual-band ARs has already been demonstrated on Ge, ZnSe, ZnS, BaF2, and AMTIR-1.
Rugate Technologies has, under a contract with the U.S. Air Force, developed a technique for designing and manufacturing narrow notch IR filters with wider field of view than typically available. An 8% bandwidth notch filter can provide fixed wavelength laser reflection over a 160° field of view!
RTI develops unique, state of the art technology for the design and manufacture of high performance optical thin films. RTI's team is able to apply over 60 years combined experience in the rugate and discrete filter process development field as well as offer a capable interference filter and thin films laboratory.
