V-Mounts Clamps Chucks Rotator

This page contains our selection of accessories for multi-axis flexure fiber stages. These include fiber clamps, fiber holders, and axial force sensors. We also manufacture magnetic clamps that hold fibers in our V-groove fiber holders. We also offer bare fiber chucks and a rotator for Fiber Launch platforms, as well as other Fiber Optomechanics.

The V-groove fiber holders on this page are typically used to clamp fibers with the coating intact. The diagram to the right shows the structure of a typical fiber, which consists of a core, a cladding, and a coating (note that the diagram is not to scale). The coating serves to protect the cladding of glass fibers from particulates that may land on the surface of the fiber, causing it to become brittle. Although this layer may also have optical properties that allow it to double as a second cladding, it is still referred to as the coating layer due to the protective properties. The term “buffer” is often used instead of “coating” when the layer surrounding the cladding is composed of Tefzel, as this material bonds differently to the glass cladding than other common coating materials such as acrylate or TECS. Some fibers may also have an additional jacket, or buffer applied on top of the coating layer. To determine whether one of the clamps available below is compatible with the fiber used in your application, you must know the diameter of the outer layer (coating, additional jacket, or buffer layer). This value needs to be within the range of specified fiber diameters for the clamp.

  • These values are typical and do not take manufacturing tolerances into account.

The fiber holder features a grooved central ferrule with six mounting surfaces, which together accept fibers or other cylindrical objects that have an outer diameter between 125 µm to 2.66 mm. Simply rotate the ferrule to align the correct mounting groove with the clamping arm and secure with the included 4-40 (M3) setscrew. It has been designed to allow rapid mounting and dismounting of a variety of photonic components, including bare optical fibers, optical fibers mounted in ceramic ferrules, and multi-channel waveguides.

To determine whether this clamp is suitable for your application, you must know the diameter of the cylindrical object that you wish to secure in the clamp, such as the outer layer (coating or additional jacket or buffer layer) of your fiber or the size of your ferrule. The table to the right specifies the minimum and maximum diameters a cylindrical object can have in order to be securely held by each groove in the HFF001.

For a simpler clamp for coated fiber, please consider the HFF003 Quick-Release Fiber Clamp listed below.

150 µm 341 µm
  • These values are typical and do not take manufacturing tolerances into account.
  • Precision V-Groove Designed for Ø150 µm to Ø341 µm Fibers
  • Stainless Steel Construction Provides Robust, Wear-Resistant Surface
  • Tapered End Maximizes Access to Fiber in Industrial Coupling Applications

The HFV002 Tapered V-Groove Fiber Holder, which is longer than our HFV001 Fiber Holder sold above, is designed to allow access to smaller devices. When butt-coupling fibers to small waveguide devices (particularly when the device is mounted on a waveguide manipulator), it is often difficult to support and position the end of the fibers close enough to the input ports of the waveguide with standard V-groove holders. The tapered top plate of this mount improves the user's ability to visually observe the fiber-waveguide interface.

The fiber is secured with the two provided HFM001 Magnetic Clamps. These clamps are also available separately below.

  • Actuator Knob Controls Clamping Mechanism and Allows Easy Loading
  • Angled Contact Pads Ensure that the Optical Element Sits Flat on the Support Surface
  • Also Useful for Mounting Rectangular Optics

The HFA001 Fiber Array Holder uses a single actuator knob to simultaneously move both sides of the clamping mechanism. This two-sided mechanism ensures the device being mounted is centered on the support surface. Three angled clamping surfaces provide a slight downward pressure and stable, three-point contact. The third clamping point is located at the end of a spring-loaded flexure rod that allows the holder to adapt to differently sized optical elements.

Multi-Axis Flexure Stage Accessories: Axial Force/Touch Sensor Platform

  • Load Capacity: 30 N (6.7 lb)
  • Sensitivity: 0.03 N (0.0067 lb)
  • 62.5 mm Deck Height with AMA034 Support Post
  • 112.5 mm Deck Height with AMA035 Support Post

The FSC103 Axial Force Sensor is a force-sensing cell that can be used to position an optical fiber with respect to another device in the direction of the optical axis. When the fiber makes contact with the device, a force arises that is detected by a strain gauge. This generates an electrical signal that is sent to the actuator controller to indicate that the desired position has been reached.

These cells mount in the groove of our AMA034 and AMA035 Post Assemblies. The AMA034 delivers a deck height of 62.5 mm (optical height of 75 mm), which is the same as our 3-axis NanoMax, RollerBlock, and MicroBlock platforms. In contrast, the AMA035 delivers a 112.5 mm deck height (optical height of 125 mm), which matches our NanoMax 600 6-axis stages.

The FSC103 sensor is compatible with the other flexure stage accessories sold on this page. The TSG001 T-Cube Strain Gauge Reader is ideal for monitoring the output of the stage's sensor. A PAA622 cable is included with the force sensor for connection to the strain gauge reader.
