The LBTEK coaxial system adjustment mount is compatible with 30 mm coaxial systems, suitable for the installation and adjustment of mirrors in coaxial systems. It offers two types of adjustment mounts: double retaining ring fixation (AMC-1A, TXY1SM1) and set screw fixation (AMC-1B). AMC-1A and TXY1SM1 feature an SM1 threaded through-hole and come with two SM1R retaining rings, suitable for mounting Ø25.4 mm optical components. The SM1 thread is compatible with all LBTEK mechanical components featuring SM1 threads. AMC-1B is equipped with a Ø25.4 mm smooth-walled hole and uses M4 set screws (compatible with a 2 mm hex wrench) to secure optical components, suitable for mounting Ø25.4 mm optical elements with a minimum thickness of 3 mm. The rear panel of the mount includes four Ø6 mm through-holes, compatible with 30 mm coaxial systems, and features M3 or M4 locking screws on the side to secure coaxial rods. The mount is equipped with three adjusters (M6×0.25), offering a precision of 0.32° per revolution, enabling adjustment of the front panel's deflection and tilt angles. It supports a maximum linear adjustment range of ±3 mm. The unique adjustment knob design provides greater torque, and the adjusters can also be fine-tuned and secured using a 2 mm hex wrench. The rear panel includes M4 threaded holes for mounting optical rods.
