An Omni-Scope is a rare Imperial sighting device which is mounted on certain Imperial personal weapons. A cluster of various sensors tied to a precision lens, an Omni-Scope incorporates telescopic and infrared vision sensors.
Some Omni-Scopes can also plug directly into the shooter's bionic cranial port if they possess one, allowing it to become their "third eye" and grant the ability to see and shoot wherever the weapon is aimed.
Omni-Scopes are incredibly expensive and are often used by renowned bounty hunters and assassins, as well as certain elite members of the various Imperial armed forces including the Space Marines, dating back to the time of the Great Crusade.
