LBTEK 2-inch weak-magnetic series optical mounts provide a high Stability, low-magnetic-interference precision alignment solution for Ø50.8 mm Optical Components. This series supports left/right-hand interchangeable mounting and flexibly adapts to Optical Path layouts. Optical Components can be quickly clamped via Flexure Springs and fixing screws, or a Retaining Ring can be used for conventional threaded locking, meeting different experimental habits and lens Thickness requirements. The adjustment mechanism uses M6×0.25 precision threaded Adjusters, enabling fine angular adjustment of ±4° in the Pitch / Yaw directions. The body of the NMMT series is made of 316L Stainless Steel. After machining, it undergoes a special treatment that fully restores the magnetic martensite generated during machining into a Non-Magnetic austenitic structure. This process enables it to inherit the excellent Thermal Stability provided by the low Coefficient of Thermal Expansion of 316L Stainless Steel, while ensuring extremely low relative permeability of the complete unit (outer flat surfaces <1.05, holes and curved surfaces <1.08). At the same time, all auxiliary accessories are made of weakly magnetic or even Non-Magnetic materials.
