An imaging system for directing one or more optical signals to one or more imaging elements is provided. The imaging system may include an optical element tray. The optical element tray may include optical elements having optical characteristics different from each other. The optical element tray may be configured to be moveable to form one or more optical paths each allowing an optical signal to travel to an imaging element through none, one, or several of the optical elements. In various embodiments, the one or more optical paths may each be selected from a plurality of linear and nonlinear paths formed by the optical elements in the optical element tray and/or additional optical elements external to the optical element tray. In some embodiments, the optical element tray may be moveable along its axis of rotation and/or rotated to enhance image stability of the imaging system.
