The LBTEK rotary mount is typically used for mounting Ø12.7 mm or Ø25.4 mm polarization optics. It allows continuous 360° rotation with 2° graduation accuracy and can be locked in place using screws located on the side or top. The mount is available with either SM1 external or SM1 internal threads, enabling direct connection to SM1-threaded optomechanics such as SM1 lens tubes or 30 mm cage plates. The central aperture is SM05- or SM1-threaded, and optics are secured using the included SM05R or SM1R retaining rings.
The LBTEK dual-axis rotation mount consists of a dual-rotation base and two rotating mounting rings, designed to hold two Ø25.4 mm optical components. Both rings feature SM1 internal threads and can secure optics up to 6.4 mm thick using the included SM1R retaining rings. The mounting rings are magnetically attached to the base, allowing quick installation and removal, and enabling fast swapping of different optical components by simply replacing the inner rings. Each mounting ring features a knurled edge for rotation adjustment and a 360° graduated dial with 2° per-division markings for repeatable positioning. Two M4 thumb screws on the top can be tightened with a 2 mm hex key to lock the rings in place. Once locked, the locating holes on the base maintain a stable three-point contact, securing the rotation rings. The distance between the two installed optics is 7.6 mm. The base is equipped with M4-threaded holes for post mounting.
Note: It is recommended not to use the dual-axis rotation mount together with lens tubes, as the torque applied to the optical mounting holes may overcome the magnetic holding force.
