LBTEK Standard O-Type 2D Optical Mounts are designed for adjusting mirror angles. There are two structural types: one with a plain through-hole (no thread), where the optical element is secured using nylon-tipped set screws; the other with SM internal threading, where the optical element is fixed with two external-thread retaining rings. Models AMM-05A and AMMC-05B use two M5×0.25 adjustment screws to provide ±4° pitch and yaw adjustment. Models AMM-05B and AMM-05B-SP use two M6×0.25 adjustment screws for ±4° pitch and yaw adjustment. The ends of these adjustment screws feature internal hex sockets, allowing adjustment with a 2 mm hex wrench. Other mounts in this series use two M6×0.25 adjusters to provide ±4° or ±3° pitch and yaw adjustment. These adjusters are fitted with knurled knobs for manual operation. The base of the mounts includes two M4 countersunk or threaded holes, while models AMM-2A and AMM-2B feature six M4 countersunk holes. The AMM-05B-SP model includes a Ø4.2 mm through-hole for connection to optical posts.
LBTEK A-Type Standard O-Type 2D Optical Mounts feature an internally threaded through-hole, where optical elements are secured with two retaining rings. Models AMM-05A, AMMM-1A, and AMM-1A have two M4 countersunk holes at the base, while AMM-2A has six M4 countersunk holes for connection to optical posts. Model AMM-05A uses two M5×0.25 adjustment screws to achieve ±4° pitch and yaw adjustment, while the other models are equipped with two M6×0.25 adjusters. Among these, AMM-2A provides ±3° pitch and yaw adjustment, while the others provide ±4°. Models AMM-1A and AMMM-1A can hold Ø25.4 mm optics with a maximum thickness of 3.9 mm, AMM-05A supports Ø12.7 mm optics with a maximum thickness of 3.8 mm, and AMM-2A supports Ø50.8 mm optics with a maximum thickness of 5.2 mm.
