LBTEK Weak Magnetic Series Cube Beamsplitter Mount provides a high Stability, low magnetic interference alignment solution for cube beamsplitters. It is used to install weakly magnetic beamsplitter cubes into 0.5-inch or 1.0-inch set screw type Optical Components adjustment mounts, allowing the transmitted beam to pass through the Clear Aperture of the adjustment mount, for Pitch and Yaw adjustment of the beamsplitter cube. It features four-sided clear aperture and a large clear aperture area. The body of the NMMT series is made of 316L Stainless Steel. After machining, it undergoes a special treatment to fully restore the magnetic martensite generated during machining into a Non-Magnetic austenite structure. This process enables it to inherit the excellent Thermal Stability of 316L Stainless Steel due to its low Coefficient of Thermal Expansion, while ensuring an extremely low relative permeability of the whole unit (outer plane <1.05, holes and curved surfaces <1.08). At the same time, all accessories are made of weakly magnetic or even Non-Magnetic materials.
