A system for directing light to an imaging element is provided. The 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 an optical path allowing the light to travel to the imaging element through none, one, or several of the optical elements. In various embodiments, the optical path may be selected from a plurality of linear and nonlinear paths formed by one or more optical openings, one or more optical channels, and optical reflectors.
