Abstract
A combination day/night sight includes an image intensifying sensor/display combination and a daytime optical path length compensator that may be selectively placed within the optical path. Use of the optical path length compensator when the image intensifying sensor/display is not being used eliminates the need for moving optical elements. The night sight therefore requires no change in focus or bore sight adjustment after switching between day and night operations.
