The Q-RG-12 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-12 provides maximum spacing between the centerlines of 2 Cubes at 12 inches. Note that the actual Q-RG-12 is only 10 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 10-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.

Q-RG-12导杆可以安装和定位光学元件，如透镜和偏振器之间的两个立方体。棒的长度大小是为了使立方体的中心线以偶数英寸的增量间隔，这种增量由零件号中的后缀表示，例如，Q-RG-12在12英寸处提供了两个立方体中心线之间的最大间距。请注意，实际的Q-RG-12只有10英寸长。这些杆安装在立方体5个开口侧中的3个上的4个钻孔上，为光学安装模块提供支持，如Q-XIPR-1偏光旋转器或Q-XILP-1透镜定位器。一个立方体也可以以同样的方式安装在另外两个立方体之间，使用4个通孔。每个连杆上都有一个单独的紧定螺钉，这样使用时可以将立方体锁在连杆上。支架和立方体都可以沿杆轴向移动，以实现透镜聚焦或其他类型的对准。这个10英寸长的导杆在一端抽头，在另一端有一个螺纹螺栓，这样就可以把它堆起来。每个杆都有一个孔，这是交叉钻孔，以帮助收紧和放松。
