1. A sight system comprising: an optical system having an optical axis and adapted to receive light from a scene; an electronic display adapted to provide an image to the optical system along a first axis different from the optical axis; a first light source adapted to illuminate the electronic display to provide the image; wherein the optical system is adapted to pass the scene light and the image along the optical axis to superimpose the image on the scene light; a prism adapted to receive the superimposed image and the scene light along the optical axis; a second light source adapted to project additional light into the prism along a second axis different from the optical axis and the first axis to superimpose a reticle on the scene light; wherein the prism is adapted to pass the superimposed image, the superimposed reticle, and the scene light for viewing by a user of the sight system; and wherein the image comprises an infrared image of the scene, a thermal image of the scene, or a low light image of the scene received from a camera.
