Image beam deflecting means are interposed between the objective lenses and the parallel combination. During nighttime use of the sight, the deflecting means are used to apply the incoming image beam to the image intensifier. During daytime use of the sight, the deflecting means are used to apply the incoming image beam to the optical array.
