Thorlabs' FiberBench Polarization Controller Kits allows you to transform an arbitrary input polarization state into an arbitrary output polarization state. These controllers use two FiberPorts mounted on either side of a Single-Axis FiberBench with HCA3 Wall Plates. Any input polarization state can be deterministically rotated into a known output polarization state using a quarter-wave, half-wave, and another quarter-wave plate mounted (in this order) between the two FiberPorts. Each plate can be precisely and continuously rotated through 360°.

Advantages over Traditional Fiber Paddle Controllers
The FiberBench Polarization Controller Kits have the same function as paddle controllers, while offering more deterministic and stable polarization manipulation. Since it does not have any hysteresis, it is possible to predict the FiberBench Polarization Controller's output State of Polarization (SOP) at any instant in time given only its input SOP. Without a polarimeter, the SOP from the paddle controller cannot be determined directly. Unlike the conventional fiber paddle controllers, the FiberBench polarization controllers can be used with PM or SM fiber without the need for splicing. Additionally, it benefits from the advanced design of the FiberBench series and has high thermal and mechanical stability. The continuous, 360° rotation and precise adjustment capabilities offered by the wave plates allow the user more control and a more stable platform than is possible with the paddle controllers.

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.
