ABSTRACT A one piece frame for holding a holographic element in a holographic system, and comprising a border portion, a seating portion, and a plurality of lateral positioning tabs. The border portion forms an outside border of the frame, and is flexible between an open position for receiving the holographic element and a closed position for holding the holographic element in the frame. The seating portion is connected to and extends inward from the border portion to seat against a back surface of the holographic element. The lateral positioning tabs are connected to and extend inward from the border portion, above the seating portion, and are spaced apart from each other along the border portion to hold the holographic element therein spaced from said border portion. The border portion is biased toward the closed position to hold the holographic element against the lateral positioning tabs in a fixed position in, and with a preset angular orientation relative to, the frame, and to cooperate with the holographic element to maintain the frame in a fixed preset shape to facilitate placing and holding the holographic element in a precise location and orientation in the holographic system.
