Aegis Qube Guide Rod, 8 in. Length, 6.25 mm Diameter, 4-40

The Q-RG-10 Guide Rod enables the mounting and positioning of optical components such as lenses and polarizers between two cubes. The rod length is sized to space the cube's centerline at an even inch increments which is indicated by the suffix in the part number, for example, the Q-RG-10 provides maximum spacing between the centerlines of 2 Cubes at 10 inches. Note that the actual Q-RG-10 is only 8 inches long. The rods mount to the 4 counterbored holes found on 3 of the 5 open sides of a cube, providing support for optics mounting modules such as the Q-XIPR-1 Polarizer Rotator or the Q-XILP-1 Lens Positioner. A cube can also be mounted in the same way, between two other cubes, using the 4 through holes. A separate set screw is provided with each rod to lock the cube to the rod when used in this way. Both the mounts and the cube can be moved axially along the rods to enable lens focusing or other types of alignment. This 8-inch-long guide rod is tapped on one end and has a threaded stud on the other, which allows it to be stacked. Each rod has a hole, which is crossed-drilled, to assist in tightening and loosening.
