OETI was organized in 1984, and since then has been engaged in the design, development and manufacture of patented, non-tracking concentrating solar collectors, and the installation, and service of all types of solar energy systems. The main thrust of this effort has been to reduce the complexity, and cost of solar thermal products and increase their reliability by reducing the number of their components through the use of optical concentration. In 1997, OETI was reorganized to provide expanded electro-optical, electronic, mechanical, and instrument system design and development services from concept definition, system and worst case analyses, design, fabrication, and test of electro-optical instruments and/or subsystems of larger electro-optical systems for ground and space utilization. OETI has a staff of interdisciplinary senior level engineers/managers, having a cumulative experience of over 150 man-years, who have worked closely together for over 10 years. Our products have been installed locally in Fairfield County Connecticut for homeowners, as well as nationally and internationally by aerospace companies and universities.
