Features

  • Ideal for Angle-Sensitive Setups Involving PM Fiber
  • Smooth, Continuous 360° Rotation
  • Options for Bare Fiber and Fiber Chucks

Both the HFR007 High Precision Bare Fiber Rotator and the HFR001 Fiber Chuck Rotator are designed for continuous rotation of fiber in angle-sensitive setups. Either of these rotators can be combined with our line of Multi-Axis Flexure Stages to form orientation-dependent fiber launch systems. Thorlabs also offers a line of complete fiber launch assemblies configured for SM and PM fiber.

High-Precision Bare Fiber Rotator
The HFR007 Fiber Rotator readily accepts uncoated fiber with an outer cladding diameter of 125 µm. The fiber is easily loaded into the rotator's V-groove, and a swing arm holds it in place using a strong magnetic force. It features a graduated knob that allows high-precision rotations accurate to approximately 2°, and features a 3 mm wide key on the bottom so that it can be easily mounted onto any of our multi-axis flexure stages.

1/4" Fiber Chuck Rotator
The HFR001 Fiber Chuck Rotator allows smooth rotation of 1/4" fiber chucks, and features RMS-threading (0.800"-36). Three nylon-tipped setscrews hold the fiber chuck in place. It can be attached to any of our multi-axis flexure stages using an HCS013 objective mount.

Multi-Axis Stage Selection Guide

In the above application, a 3-Axis NanoMax flexure stage is aligned in front of a 6-axis stage at the proper 112.5 mm deck height using an AMA554 Height Adapter.

3-Axis Stages
Thorlabs offers three different 3-Axis Stage variations: NanoMax flexure stages, MicroBlock compact flexure stages, and RollerBlock long-travel stages. Each stage features a 62.5 mm nominal deck height. Our NanoMax line of 3-axis stages offers built-in closed- and open-loop piezos as well as modular drive options that include stepper motors, differential drives, or additional piezos. The MicroBlock stages are available with differential micrometer drives or fine thread thumbscrews; these drives are not removable. Finally, our RollerBlock stage drivers can be switched out for any actuator that has a Ø3/8" (9.5 mm) mounting barrel.

4- and 5-Axis Stages
Our 4- and 5-axis stages are ideal for the static positioning of waveguides or complex optical elements with respect to our 3-axis or 6-axis high-performance alignment stages. Thorlabs' 5-axis stages have nominal heights of 62.5 mm or 112.5 mm. The AMA554 Height Adapter can be used to raise the deck height of the 3-axis or 4-axis stages to 112.5 mm for compatibility with our 5-axis MicroBlock or 6-Axis NanoMax Stages.

6-Axis Stages
Thorlabs' 6-Axis NanoMax Nanopositioners are ideal for complex, multi-axis positioning and have a nominal deck height of 112.5 mm. These stages offer a common point of rotation and a patented parallel flexure design that allows all actuators to be coupled directly to the base to minimize any unwanted motion in the system. Built-in closed- and open-loop piezo options are available. A selection of modular drive options allows any axis to be manual or motorized with the option for external piezos. Our units without included actuators are also available in right- or left-handed configurations. To increase the stage height of the 3-axis stages to 112.5 mm, we recommend our AMA554 Height Adapter, shown in the image to the right.

A complete selection and comparison of our multi-axis stages is available below.

Half of these rotation stages requires fiber chucks which arent included. It owuld be really helpful if those options were listed on the page next to the compatible rotation stages

Maximum Eccentricity
of the HFR007 is ±5 µm
When Rotated Over 360°
  • 10 µm Maximum Eccentricity Over 360° Range
  • Graduated Knob (5° Increments)
  • Easy-to-Load V-Groove Design
  • Swing Arm with Magnetic Clamping Force
  • Clamps on Fiber Cladding to Minimize Offset Errors
  • Accepts Fiber with Ø125 µm Cladding (with Buffer Removed)
  • Locking Setscew

The HFR007 Fiber Rotator can rotate a single mode fiber about the center of the fiber core with a maximum eccentricity of 10 µm when rotated through 360º. Fibers are easily loaded into the V-groove on the fiber rotator and quickly secured by lowering the swing arm that is magnetically held in place. The force used to secure the fiber is adjustable so that the stress induced birefringence can be controlled. The precision fiber rotator allows for top loading of the fiber and provides smooth, continuous 360° rotation.

An engraved graduated knob with 5° increments allows the angular position to be set with an accuracy of ~2°. Once the position is set, a locking screw can be used to fix the angular position of the fiber core.

The precision fiber rotator is pre-adjusted for fibers with an outer cladding diameter of 125 µm (with the buffer coating removed). The coating, sometimes also referred to as a buffer, serves to protect the cladding of glass fibers from particulates that may land on the surface of the fiber, causing it to become brittle. The coating of certain specialized fibers can have optical properties that allow it to act as a second cladding layer. In these cases, the optical properties of the fiber should be considered before stripping off the coating layer.

The HFR007 has a 3 mm wide key on the base, making it compatible with our entire line of flexure stages, roll, pitch and yaw platforms, and fixed platforms and brackets. We also offer bare fiber clamps and chucks, as well as other Fiber Optomechanics. Flexure stage top plates have a central keyway along one or two axes of the stage. This keyway allows all the flexure stage accessories to be accurately placed along the central axis of the stage so that only fine adjustments need to be made to the optical alignment of the system when an accessory is removed and then replaced.

  • Smooth, Low-Friction Fiber Rotator
  • Designed for 1/4" Fiber Chucks
  • RMS-Threaded (0.800"-36) Mounting Feature Enables Incorporation into Existing Mounts
  • Three M3 Nylon-Tipped Setscrews Secure the Fiber Chuck

The HFR001 Fiber Chuck Rotator rotates a standard 1/4" fiber chuck, such as the HFC005, continuously over 360°. The fiber chuck is secured by tightening the M3 nylon-tipped setscrews with a 1.5 mm hex key. The HFR001 has an external RMS thread, which when mounted in an HCS013 microscope objective mount, can be secured to the top plate of one of our multi-axis flexure stages or fixed brackets.

The phosphor-bronze and PTFE bearing in the fiber chuck rotator provides smooth, low-friction rotation for precise angular orientation of a polarization-maintaining fiber. The lateral offset during rotation is typically less than 20 µm; this relatively small offset allows a single mode fiber at Ø1.5 µm to be rotated by about 90° before requiring compensation with the Y and Z adjustments on the flexure stage. The HFR001 can also be used with the a roll/pitch platform (e.g., AMA027) to launch light into polarization-preserving fibers. This combination provides 360° of initial fiber rotation with 8° of fine rotation.

The photo to the right shows a typical application. The fiber chuck rotator holds the fiber, whose output is aligned with the microscope objective, which is threaded into the objective holder and mounted on a fixed bracket. The HFR001 is held in a HCS013 Objective Holder and mounted to an 3-Axis Flexure Stage.

Please note: the HFC007 fiber chuck should not be used with the HFR001 fiber rotator, as it does not provide sufficient clamping force to prevent rotation of the fiber once placed inside the rotator.
