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.

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.
