Abstract
A sighting device is used to aim along a line of sight at a target. The sighting device includes a reticle structure formed of a roof prism assembly having an inclined final roof-prism mirror surface that is not perpendicular to the line of sight. The inclined final roof-prism mirror surface is the last surface of the roof prism assembly from which an optical path of the target reflects before leaving the roof prism assembly. There are two sets of sighting reference features, wherein the sets of sighting reference features are disposed on the inclined roof-prism mirror surface. A separately operable illumination source is provided for each of the sets of sighting reference features, wherein each illumination source illuminates only one set of sighting reference features.
