Adjustable Lens Tube SM05-8V

The LBTEK internal and external threaded lens tube features SM05 external threads on one end and SM05 internal threads on the other, primarily designed to secure optical components with a diameter of Ø12.7 mm. It allows for axial adjustment of the optical component's position through rotation along the optical axis. Once the desired position is achieved, it can be locked in place using an external retaining ring (SM05NR). Additionally, each lens tube comes with an SM05R retaining ring for securing the optical component. The SM05-8V model has both internal thread depth and external thread length of 12.5 mm, with a maximum installation thickness of 10.8 mm for Ø12.7 mm optical components. The adjustable range has a minimum value equal to the thickness of the external retaining ring, while the maximum value is the total length of the external threads minus the thickness of the external retaining ring and a minimum thread engagement depth of 2 mm.
