Spectra-Mat, Inc. (SMI) is a materials technology company established in 1963 to serve the requirements of the microwave tube industry. SMI continues today as a major supplier of impregnated cathodes and other components for vacuum power devices used in commercial, research and defense applications.

From its foundation of porous material technology SMI formed a materials group in the early 1990’s that addressed the following: (1) requirements for controlled expansion matching for thermal management in microelectronic, optoelectronic, LED and concentrated photovoltaic devices; (2) the need for high purity tungsten for ion implantation processing; and (3) non-lead based x-ray attenuation material. The primary materials developed for these applications are tungsten copper, molybdenum copper, and tungsten alloys.

In early 2008, Spectra-Mat, Inc. was acquired by SAES Getters USA, Inc., and became A Member of SAES Getters Group, headquartered in Lainate, Italy. SAES Getters is an innovative and customer oriented company who is a world leader in industrial and scientific applications requiring stringent vacuum conditions or ultra-high pure gases (www.saesgetters.com). The synergy of our companies provides a stronger base for the support of all of our current products as well as new development efforts. Our combined focus will continue to be on providing innovative material solutions for our customers’ requirements.
