EOTech designs, manufactures, and markets electro-optic products and systems. The company is headquartered in Ann Arbor, Michigan. They produce holographic weapon sights for small arms that have been adopted by various military and law enforcement agencies as close quarters battle firearm sights.

They also have roots in the Environmental Research Institute of Michigan (ERIM), a non-profit R&D institute. Of the many inventions by ERIM researchers, some were in the fields of synthetic aperture radar, laser holography, and aircraft head-up displays.

As of 2012, EOTech primarily manufactures holographic weapon sights. EOTech was the first company to create these types of sights, having solved the problem of wavelength instability exhibited by laser diodes. They developed achromatic holographic optics that compensate for any change in the emission wavelength of the laser diode with temperature. The sights are designed to be mounted on small arms via a MIL-STD-1913 Picatinny or Weaver rail, and powered by either AA, N or CR123 size batteries for up to 1,100 hours of runtime. Sights display either a 65 MoA ring with a 1 MoA dot in the center, a single 1 MoA dot, a vertical series of dots for bullet drop compensation in certain calibers, or, in the case of their less-lethal sights, a flared vase-like sight to assist in the aiming of bean-bag or rubber ball rounds commonly used in riot control. Bushnell marketed the non-military versions under the brand name "Holosight". The EOTech 553 is in U.S. military service under the designation SU-231/PEQ and M553 in the commercial market. More recently, the U.S. Military is also purchasing and issuing the newer EOTech EXPS3 model, designated the SU-231A/PEQ. A specialty sight for the grenade launcher has also been accepted by the U.S. military with the designation SU-253/PEQ. Their first holographic sight was introduced in January 1996.
