The LBTEK coaxial system three-axis adjustment mount is compatible with 60 mm coaxial systems, suitable for the installation and adjustment of mirrors in coaxial systems. It offers two types of adjustment mounts: dual retaining ring fixation (AMC-2A) and set screw fixation (AMC-2B). The AMC-2A features an SM2 threaded through-hole and includes two SM2R retaining rings, suitable for mounting optical components with a diameter of Ø50.8 mm and a maximum thickness of 5.2 mm. The SM2 thread is compatible with all LBTEK mechanical components featuring SM2 threads. The AMC-2B has a Ø50.8 mm smooth-walled hole and uses M4 set screws (compatible with a 2 mm hex wrench) to secure optical components, suitable for mounting optical components with a diameter of Ø50.8 mm and a minimum thickness of 4 mm. The rear panel of the mount has four Ø6 mm through-holes, compatible with 60 mm coaxial systems. The side features an M3 locking screw (compatible with a 1.5 mm hex wrench) for securing coaxial rods. The mount is equipped with three adjusters (M6 x 0.25), offering a precision of 0.2° per rotation, allowing adjustment for ±3° deflection and tilt angles on the front panel. 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 (3 locations) for mounting optical rods.
