These mirror modules incorporate an enhanced gold-protected mirror mounted on a flexure base. The base allows for tip, tilt, and rotational adjustment for precision beam alignment and steering control. The modules are mounted to provide easy access to the adjustment mechanism without interfering with the beam path. The mirror is positioned off axis from the center beam path such that it will intersect the displaced beam from a preceding polarizer and reflect it by 90°. The PBB polarizer and MYOB mirror can be combined to create a Polarization Splitter (see the Application Tab for more details).
Care should be taken to choose a mount that directs the beam to the correct port's path so that the adjusting screws are in a convenient position for the required setup. Please see the Pin Configuration Tab for help in selecting between vertical and horizonal mounting orientations, as well as left- and right-handed orientations.
The flexure base has two basic pin mounting orientations: vertical and horizontal. Although the vertical pin configuration is the most common, both the vertical and horizontal pins are compatible with our FiberBenches. Please be careful about sending the beam to an available port. A vertical pin configuration is defined as having the pins mounted parallel to the rotation adjustment screw. In the horizontal configuration, the pins will be mounted perpendicular to the rotation adjustment screw.
The flexture bases are also seperated by handedness: right or left. The right or left designation will determine the orientation of the cube, plate, or mirror with respect to the rotation adjustment screw and refers to how the beam will be turned. See the sketches and diagrams below for help in selecting a component.
A Polarization Splitter can be assembled using the components listed in the below table. The MYOB mirror is positioned such that it will intersect the displaced beam from the preceding PBB polarizer and reflect it by 90°. This combination simplifies the alignment of complex systems by de-coupling the transmitted and reflected beams, thus allowing for the independent adjustment of each beam path. Alignment is critical when aligning systems with a PBB/MYOB combination as clipping can occur if the beam is too large or not centered.
