In 1972, the Michigan State Legislature established an independent, non-profit research institute, Willow Runs Laboratories. It was later renamed Environmental Research Institute of Michigan (ERIM).
Two decades later, in 1993, ERIM formed Michigan Development Corporation (MDC) to commercialize ERIM technology and create spin-off companies.
In 1995, MDC created EOTech as a wholly-owned subsidiary of ERIM.
EOTech, a division of L-3, delivers cutting edge technology and products in the fields of holographic sighting systems, tactical lasers, illuminators and thermal imaging equipment. EOTech is dedicated to providing high-quality battle-tested products to law enforcement and commercial markets around the world.
