Three Electrons Infrared (3EIR) was established in 2021. Founded by two industry veterans, one with engineering expertise designing lasers, the other specializing in night vision optics, combined their talents to create products designed to meet the needs of the community. Their primary focus was innovation, rapid prototyping and getting American made IR lasers quickly to the market.  

Tremendous attention was put in designing the user interface, The mode selector switch is intuitive and can be operated with eyes closed. It was simplified so that under stress the user could rapidly find their desired setting. The activation button was placed center rail, so it was both ambidextrous and compatible with a c-clamp grip. Additionally, the 3EIR product never interferes with day optic. Its maximum height is just .6 inches above the rail. The DIR-one is a mere .4 inches above the rail.
