The LBTEK BFR05A is a rotational mount compatible with fiber coupler mounting bases, designed to accommodate Ø12.7 mm optical components with a clear aperture of Ø11.4 mm. It features SM05 threads for mounting optical elements, Ø1/2-inch lens tubes, and other SM05-threaded accessories. This rotational mount is suitable for installing Ø12.7 mm polarizers and waveplates, with a white engraved marking area at the bottom for labeling mounted optical components. The BFR05A rotational mount offers a scale accuracy of 2°, supports 360° continuous rotation, and provides both coarse repeatable positioning and fine adjustment. The top includes an M3 hex screw for locking the rotational mount in place, while the bottom is equipped with two 3.175 mm locating pins for installation and precise positioning.

The LBTEK BFRP05A stainless steel high-precision rotation mount is designed for fiber coupling systems. The SM05-threaded rotating part of this mount features a knurled edge for 360° coarse adjustment. After securing the fine-tuning screw with a 1.3 mm hex wrench, precise positioning can be achieved by rotating the threaded subassembly at the top of the component using a 1.5 mm hex wrench, with one full rotation corresponding to approximately 1.3°. The main scale graduation accuracy is 2° per division, while the differential scale reading accuracy is 5′. It can accommodate Ø12.7 mm optical components, SM05 lens tubes, and other SM05-threaded accessories. This mount is particularly suitable for installing Ø12.7 mm polarizers and waveplates.

The LBTEK BFT4-5C and BFT4-1P four-axis adjustment mounts are designed for fiber coupling systems. The BFT4-5C is used to mount 5 mm edge-length cubes, such as polarizing or non-polarizing beam splitter cubes, while the BFT4-1P is designed for mounting flat optical components with a width of 12.7 mm and a thickness of 1 mm, such as beam splitters or mirrors. A dot is marked at the 0-90° midpoint for installing beam-splitting optical elements, ensuring that the coated surface of the splitter faces this dot. This alignment allows the incident beam to be centered on the mount for optimal beam splitting. Both mounts utilize UV adhesive for installation. These adjustment mounts enable precise beam alignment and directional control through pitch, tilt, and rotation adjustments. Three threaded mechanisms control the pitch/tilt and rotation of the mount, providing a maximum adjustment range of ±3°. The rotation direction allows for 360° coarse adjustment, with 5° incremental markings and a differential scale precision of 1°. After locking the fine-adjustment screws on the side, the top threaded mechanism enables ±12° fine adjustment at approximately 2° per turn. Additionally, when all three vertical threaded mechanisms are rotated equally, they provide ±1 mm vertical adjustment. All threaded mechanisms, including the fine-adjustment locking screws, use a 1.3 mm hex key, which is included with each mount. Furthermore, a spanner wrench is provided to secure the threaded mechanisms and prevent accidental movement. One of each tool is included.

LBTEK 12.5 mm Diameter Mount BFM-05A is suitable for mounting optical components with Ø12.7 mm or Ø12.5 mm diameters, with a maximum mounting thickness of 4 mm. It features an optical component mounting step and includes one SM05R retaining ring for securing the optical component. The base is equipped with two 3.175 mm diameter dowel pin holes for installation and positioning.

LBTEK Sleeve Mount Adapter BFM-05B, designed for mounting SM05 sleeves, secured with M4 nylon-tipped screws. After tightening, the optical axis height is fixed at 14.3 mm. The base features two 3.175 mm diameter dowel pin holes for installation and positioning.

The LBTEK free-space isolator mount allows free-space isolators to be adapted to a five-axis fiber coupling system. It is secured using a 2 mm hex wrench via M4 rubber-tipped screws to align the optical axis with the isolator. The base features two 3.175 mm diameter cylindrical pins for installation onto our five-axis fiber coupler mount.

The LBTEK 30 mm coaxial system adapter BFOPM-30 is designed for fiber optic coupling assemblies, enabling the integration of our five-axis fiber optic coupling accessories with 30 mm cage systems. It features two pin holes that allow the optical component mounts from our fiber coupling accessories to be installed and secured using a 1.5 mm hex wrench. The mount includes two snap-in flexible clamps for attaching our Ø6 mm cage rods, which can be locked in place with a 1.5 mm hex wrench. The coaxial holes feature a snap-in design, allowing components to be easily inserted and removed without disassembling the entire coaxial system. When this mount is used within a coaxial system and the coaxial system is attached to the coupling system via the FP-OPM30 coaxial plate, all optical components maintain the same beam height of 14.3 mm. An M4 threaded hole at the base of the BFOPM-30 mount allows it to be secured to an OP-XX series post. Please note that this cage system mount is not compatible with fiber coupler accessories that exceed 19 mm in width perpendicular to the optical axis.
