The specification discloses a mount for an optical device having 6 degrees of freedom; three translations along the x, y and z axes and three pivotal or rotational movements about each of the axes. The mount is particularly useful in mounting scanning cameras, robotic eyes, or correlating image or pattern recognition devices for use in self- guided missiles. When used in free-flight, the three pivotal or rotational movements correspond to pitch, roll, and yaw. A semi-spherical drive means which is rotatably journaled in a complimentary semi- spherical fixed mount. The drive means defines an optical axis within having interior threads. A first carrier is threaded into the drive means and translated along the z axis by rotation of the spherical drive means. A second carrier is mounted for x, y translation within the first carrier. Pivotal or rotational movement about the x and y axes may occur between the first carrier of the drive hemisphere, or between the drive hemisphere and the fixed mount. Roll movement about the z axis occurs between the first carrier and the fixed mount.
