Ernst Leitz Canada (ELCAN) is a Canadian optics and electronics company owned by American defense contractor Raytheon. ELCAN manufactures devices geared towards civilian and military markets. The company currently has a location in Midland, Ontario. ELCAN optics are sold through Armament Technology Incorporated and their channel of dealers.
ELCAN is perhaps best known for making the 3.4x28 power ELCAN C79 optical sight that is widely used on the Diemaco C7, FN MINIMI, FN MAG and CZ-805 BREN families 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.
The M145 machine gun optic differs from the C79's 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. It is used by the US military for its M249s and M240s.
ELCAN manufactures the Specter line of combat optics. They come in a variety of configurations. Specter DR 1.5x/6x, DR 1x/4x, 4x Optical Sight and TR 1/3/9 are available with a 5.56mm or 7.62mm ballistically matched reticle.
