ELCAN (Ernst Leitz Canada) is a Canadian optics and electronics company owned by Raytheon.
The company manufactures devices for civilian and military markets. The company has locations in Midland, Ontario, Richardson, Texas and Málaga, Spain.
ELCAN is perhaps best known for making the 3.4x28 power ELCAN C79 optical sight used on the Diemaco C7, FN MINIMI and FN MAG series of firearms. The C79 sight is not designed as a sniper sight per se, but is rather intended to be mounted on a variety of rifles and to be used by regular infantrymen as well as designated marksmen.
Another version of basically the same sight is the M145 machine gun optic. The M145 differs from the standard 3.4x sight in that ballistic compensation is provided for in the reticle, rather than in the mount. Reticle illumination is by a battery-powered LED with eleven intensity settings.
