The LBTEK Square Optical Oount is designed to hold Ø25.4 mm optical components with a maximum thickness of 3.5 mm. Using an SM1 retaining ring wrench, the optical component is secured in the mounting hole with the included two SM1R retaining rings. Two M6×0.25 adjustment screws with locking nuts enable ±4° pitch and yaw adjustment, with a precision of 0.4° per turn. The mount comes with three M4 countersunk holes and can be installed on a post in orientations suitable for left-handed, right-handed operation, or facing upward. The knobs on the adjusters are removable, allowing for adjustment with the included HWS-2 2.0 mm hex key with knob or a standard 2.0 mm hex key after removal, facilitating installation in narrow or confined spaces.
