LBTEK 0.5-inch weak-magnetic series optical mounts provide a high-Stability, low-magnetic-interference precision alignment solution for Ø12.7 mm Optical Components. This series supports left-right interchangeable mounting, flexibly adapting to Optical Path layouts. Optical Components can be quickly clamped via Flexure Springs and fixing screws, or conventionally locked with a Retaining Ring via Thread, meeting different experimental habits and lens Thickness requirements. The adjustment mechanism uses M4×0.2 precision Thread Adjusters, enabling fine angular adjustment of ±5° in Pitch / Yaw directions. The NMMT series bodies are made of 316L Stainless Steel. After machining, they undergo special treatment to fully restore the magnetic martensite generated during processing into a Non-Magnetic austenite structure. This process enables them to inherit the excellent Thermal Stability of 316L Stainless Steel’s low Coefficient of Thermal Expansion while ensuring an extremely low relative magnetic permeability of the entire unit (outer plane <1.05, holes and curved surfaces <1.08). Meanwhile, all auxiliary accessories are made of weak-magnetic or even Non-Magnetic materials.
