Features

  • Beamsplitters Designed for 780 nm, 1064 nm, or 1550 nm
  • Compatible with FiberBenches
  • Mounted on Flexure Base to Provide Easy Tip, Tilt, and Rotation
  • Separated by Mounting Orientations (Vertical/Horizontal) and Handedness (Right/Left)
  • Please Contact FiberBench@Thorlabs.com for Special Wavelengths or Custom Requests

For applications that require a beam to be split or reflected, Thorlabs offers polarizing cubes and beamsplitter plates mounted on flexure bases. 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. 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.

Polarizing Beamsplitting Cube
  • Clear Aperture: Ø1.5 mm
  • Beam Deviation: 90° ± 5 arcmin
  • Wavefront Distortion: λ/4
  • Wavelengths: 780, 1064, or 1550 nm
  • Reflectance of S Component: >98%
  • Transmittance of P Component: >96% (R < 1.5%)
  • Cube Size: 5 mm
  • Tip/Tilt Adjustment: 6°

These modules consist of a polarizing beamsplitter cube mounted on a flexure base. Each module provides a polarization-dependent split with an extinction ratio that is better than 1,000:1. These modules are useful for polarization-dependent measurements and applications that require a spatial beam overlap. Please see the Pin Configuration tab for help in selecting between vertical and horizonal mounting orientations, as well as left- and right-handed orientations. Please contact FiberBench@Thorlabs.com for special wavelengths.
