Ever since Thorlabs acquired the versatile FiberBench product line from Optics For Research (OFR) in 2007, we have been fine tuning the overall design to offer more long-term stability and excellent coupling efficiency. These FiberBenches form the foundation of a nearly infinite array of miniature fiber optic systems that customers have been building for the last decade. When used with the FiberPort Collimators/Couplers, a complete optical circuit can be constructed.

The all-stainless steel construction offers the stability required when building fiber optic systems. Thorlabs offers Single-Axis and Multi-Axis FiberBenches, both of which are featured below. For basic systems that require only one input and one output path, the Single-Axis FiberBenches are ideal; for more complex systems that require multiple inputs and outputs, we recommend the use of the Multi-Axis FiberBenches.

One of the main advantages of building FiberBench systems is that all the components are aligned along common beam paths (14.3 mm above the deck) that are parallel to the base. Thus, they simplify setups that would normally require extensive alignment procedures. The equally sized and uniformly spaced mounting holes on the FiberBenches are designed to hold a wide array of FiberBench accessories. Except for some mounts that would go on the side of the FiberBenches, all the accessories have dowel pins that can be easily inserted into the FiberBenches. For more information or custom requests, please contact Tech Support.

Variable Optical Attenuator Application

A continuously variable attenuator can be assembled using the FiberBench components listed in the table below. The FiberPort collimates the beam from a SM or PM fiber, and the collimated beam then goes through a calcite beam displacerwhere it is split into its respective horizontal (P) and vertical (S) components. The orientation of the wave plate controls how much energy is in the beam. It can be rotated to give the desired attenuation - zero, partial, or full. The signal then enters a reversed calcite beam displacer where it will be recombined or further separated. The only energy that will couple back into the output fiber is the signal on the central axis. The central beam will then be focused into the output fiber by the output PAF FiberPort.

Zero Attenuation
Click to Enlarge

The RABH wave plate is rotated so that there is only one output beam; this also means that the input and output polarizations are the same.
Partial Attenuation
Click to Enlarge

The RABH wave plate is rotated so that there are three output beams. The RABH orientation will control how much energy is in each beam. The only energy that will couple into the fiber is the energy in the central beam. The attenuation range is 1 to 40 dB with any value in between.
Full Attenuation
Click to Enlarge

The RABH wave plate is rotated so that there are two output beams, which will be displaced to the left and to the right of the center. In this position, there will be minimal coupling efficiency, resulting in a maximum attenuation of 40 dB.

Smart Pack

  • Reduce Weight of Packaging Materials
  • Increase Usage of Recyclable Packing Materials
  • Improve Packing Integrity
  • Decrease Shipping Costs

Thorlabs' Smart Pack Initiative is aimed at waste minimization while still maintaining adequate protection for our products. By eliminating any unnecessary packaging, implementing packaging design changes, and utilizing eco-friendly packaging materials for our customers when possible, this initiative seeks to improve the environmental impact of our product packaging. Products listed above are now shipped in re-engineered packaging that minimizes the weight and the use of non-recyclable materials.b As we move through our product line, we will indicate re-engineered packages with our Smart Pack logo.

  • Travel-based emissions reduction calculations are estimated based on the total weight reduction of packaging materials used for all of 2013’s product sales, traveling 1,000 miles on an airplane, to provide general understanding of the impact of packaging material reduction. Calculations were made using the EPA’s shipping emissions values for different modes of transport.
  • Some Smart Pack products may show a negative weight reduction percentage as the substitution of greener packaging materials, such as the Greenwrap, at times slightly increases the weight of the product packaging.

FiberBench Wall Plates: Cage System Adapters

FiberBench Power Sampling

The HCA3-CP is used to combine a FiberBench and a 30 mm Cage System for a power sampling application. The beamsplitter picks off some of the incoming light and sends it through a polarizer to a detector, allowing the polarization state of light entering the fiber to be monitored.

FiberBench with FiberPort, HCA3-SM05 Wall Plate, 16 mm Cage System, and Ø1/2" Lens Tube

These Wall Plates allow FiberBenches to be combined with Thorlabs' Cage Systems. They can be attached to the sides of a FiberBench using the two included 8-32 mounting screws. The HCA3-SM05 features four 4-40 taps and is internally SM05- threaded (0.535"-40) for compatibility with our 16 mm Cage System and Ø1/2" Lens Tubes, respectively (see photo to the right).

The HCA3-CP can accept cage rods for 30 mm and 16 mm cage systems either simultaneously or separately. Three #8 counterbores on the bottom of the plate allow it to be mounted to one of Thorlabs' FiberBenches. The plate accepts Ø4 mm or Ø6 mm cage rods for 16 mm or 30 mm cage systems, respectively. The Ø4 mm cage rods are held in place for by locking screws that accept a 0.05" (1.3 mm) hex key. The Ø6 mm cage rods are secured using a flexure mechanism that can be tightened by a single locking screw on each side of the mount that accepts 5/64" (2.0 mm) hex keys. The port through the center is SM05-threaded, allowing it to accept lens tubes or other threaded optical components.

When combining a FiberBench with a cage system, make sure that the FiberBench is properly supported to avoid applying excess torque to the cage rods. If the cage system is low enough, the FiberBench can rest directly on the optical table. For segments of the cage system that are elevated off of the optical table, the FiberBench can be supported using a Ø1" optical post threaded into the 8-32 or M4 tap in the base.

Each wall plate includes screws for mounting to our FiberBenches. The HCA3-SM05 ships with one SM05RR retaining ring to aid in securing SM05-threaded components, while the HCA3-CP ships with two retaining SM05RR rings to secure unmounted optics up to 0.21" (5.3 mm) thick, such as Thorlabs' Premium Hard-Coated Bandpass Filters.
