About Us
Founded in 2000 and acquired by Northrop Grumman in 2009, SPI has vast expertise and proven success in developing and providing superior thin film products to our aerospace, military, and commercial customers. Our high-precision coating capabilities span the Optical & Infra-Red (UV, VIS, NIR, SWIR, MWIR, and LWIR), and the RF spectral wavelengths to meet a vast range of applications and system needs. Utilizing advanced plasma beam and magnetron sputtering deposition techniques, SPI manufactures precision optical filters, mirror coatings, and large area magnetic and resistive films.
SPI is located in Santa Rosa, California, in the heart of wine and craft beer country. Our footprint includes 50,000 sq. ft. of manufacturing space, cleanrooms and metrology.
