Rotation Mounts TRM1

The LBTEK Dual Rotation Mount consists of a dual rotation base and two rotation rings, designed for mounting two Ø25.4 mm optical components. Both rotation rings feature SM1 internal threads and can accommodate optical components up to 6.4 mm thick using the included SM1R retaining rings. The rings magnetically attach to the base for easy installation and removal, allowing quick release of different optical components by replacing the inner rings. Each rotation ring has a knurled edge and a 360° dial with 2°/graduation markings—the former for rotation adjustment and the latter for repeatable positioning. Two M4 thumb screws on top allow locking the ring position using a 2 mm hex wrench. Once locked, the base's limit holes ensure stable three-point contact mounting to secure the rotation rings. The distance between the two mounted optical components is 7.6 mm. The base includes M4 threaded holes at the bottom for connecting to posts. Note: It is not recommended to use the dual rotation mount with lens tubes, as the torque applied to the optical mounting holes may overcome the magnetic adhesion.
