Abstract: Systems and methods for providing a housing for an optical device. In one implementation, a frame for a device package is provided. The frame includes a rectangular sheet. The rectangular sheet includes an aperture, a curved interface along an interior of the aperture, an elongated portion along an outer edge of the frame, and a curved portion coupled between the elongated portion and the curved interface. In another implementation, a frame assembly for a device package is provided. The frame assembly includes a frame. The frame includes a rectangular sheet. The rectangular sheet includes an aperture, a curved interface along an interior of the aperture, an elongated portion along an outer edge of the frame, and a curved portion coupled between the elongated portion and the curved interface. The frame assembly also includes a optical window fused to the curved interface of the frame.
