LBTEK-Weak Magnetic Fixed Optic Mount

Product Description

The 316L Stainless Steel body undergoes special demagnetization treatment after machining.
Flexure Springs and Set Screws secure Optical Components
Overall relative permeability: outer plane <1.05, holes and curved surfaces <1.08

LBTEK Low-Magnetic Fixed Optic Mount is suitable for Optical Paths where the angle of Optical Components does not need to be adjusted. It can be used to mount Ø12.7 mm or Ø25.4 mm Optical Components, and the Optical Components are secured by Flexure Springs and Set Screws. The bottom features M4 Tapped Mounting Holes and can connect to Ø12.7 mm and Ø25 mm Stainless Steel Optical Posts. The NMMT series body is made of 316L Stainless Steel. After machining, it undergoes a special treatment that fully converts the magnetic martensite generated during machining into a Non-Magnetic austenitic structure. This process enables it to retain the excellent Thermal Stability of 316L Stainless Steel with its low Coefficient of Thermal Expansion while ensuring an extremely low relative magnetic permeability of the entire assembly (outer plane <1.05, holes and curved surfaces <1.08). In addition, all accessories are made of low-magnetic or even Non-Magnetic materials.

Weak Magnetic Fixed Mount

For mounting Ø12.7 mm or Ø25.4 mm Optical Components
The mounting surface has cutouts, and the Clear Aperture (CA) is relatively large.
Three-point contact mounting design for Optical Components, enabling precise positioning of the center of the Optical Components
Flexible spring leaf and fixing screws secure Optical Components.

LBTEK Weak Magnetic Fixed Mount, can be used to mount Ø12.7 mm or Ø25.4 mm Optical Components. The Optical Component mounting slot surface has a cutout, which can increase the Clear Aperture (CA). This design is especially suitable for mounting beamsplitters at a 45° angle of incidence(AOI), and can also be used to mount a Mirror. The Optical Components are secured by flexible spring clips and set screws, providing stable mounting and use.

For both the 0.5-inch and 1-inch mounts, the minimum thickness of mountable Optical Components is 2 mm. The Clear Aperture (CA) of NMMT-FLF1S is 23 mm, and the distance from the bottom of the mount to the center of the Optical Component is 19 mm. The Clear Aperture (CA) of NMMT-FLF05S is 11.5 mm, and the distance from the bottom of the mount to the center of the Optical Component is 12.7 mm. The bottom of the mount has an M4 threaded mounting hole and can be connected to Ø12.7 mm or Ø25 mm optical posts. Hex wrenches are not included with this series of products; NMHK series wrenches can be purchased from LBTEK.

The Weak Magnetic Fixed Mount is used in conjunction with the Weak Magnetic extension rod and Weak Magnetic clamp block.
