• Multi-Purpose V-Groove Insert Features 5 Different V-Grooves and 1 Flat Surface
• Accommodates Fibers or Cylindrical Optical Elements with Diameters from 125 µm to 2 mm
• Fiber Clamping Arm with Adjustable Knob Provides 0.25 - 2.0 N (0.06 - 0.45 lb) of Holding Force

This quick-release, adjustable-force fiber clamp has many features that make it our most versatile fiber clamp. The top knob is used to adjust the force that the clamping arm exerts on the fiber. This feature is useful when working with specialty fibers, such as highly birefringent fibers, photonic crystal fibers, or exotic glass fibers containing fluoride or tellurite.

The fiber holder features a grooved central ferrule with six mounting surfaces, which together accept fibers from 125 µm to 2 mm in diameter. 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.

For a simpler clamp designed for Ø250 µm fiber, please consider the HFF003 Quick-Release Fiber Clamp listed below.

• Securely Clamps Ø250 µm Jacketed Optical Fiber
• Magnet Holds Clamping Arm in Place
• Simplified Mechanical Design

This fiber clamp is intended for applications that do not require the extra features offered by the HFF001 Fast-Release Fiber Clamp listed above. The clamping arm is designed to swing approximately 120° from the clamping surface to allow easy loading of the fiber into the V-groove. A rare earth magnet is used to hold the clamping arm in place once it is lowered onto the fiber. A magnetic set screw is also embedded in the arm to provide a simple means of adjusting the clamping force.

• Secures 900 µm or 3 mm Diameter Cables
• Mounts Directly on the Deck of Our Popular Multi-Axis Stages
• Prevents Accidental Misalignment

This strain relief accessory ensures that disturbances to the fiber cable are not translated into unwanted movement of the fiber end face, saving time while setting up and running experiments. It is especially useful for large-diameter fibers.

• Precision V-Groove Designed to Hold 125 µm Diameter Fibers
• Nickel-Plated Steel Provides Robust, Wear-Resistant Surface
• HFM001 Magnetic Clamps Feature a Soft Elastomer Pad to Protect Fiber Cladding from Damage

For ease of mounting and experimental flexibility, the HFV001 Standard V-Groove Fiber Holder is an ideal solution for securing bare, single mode fibers. The fiber is held in the precision V-groove by two magnetic clamps. The clamps have a special elastomer pad that locally distorts around the fiber to provide a secure but delicate grip. The base of the holder is made of anodized aluminum, and the top plate is made of nickel-plated magnetic steel.

For a longer holder optimized for fiber coupling to smaller devices, please consider the HFV002 Tapered V-Groove Fiber Holder sold below. The HFM001 Magnetic Clamps are also available separately below.

• Precision V-Groove Designed for 125 µm Diameter Fibers
• Nickel-Plated Steel 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.

• Soft Elastomer on Bottom Surface Protects Exposed Fiber Cladding
• Sold in Packages of Six

These magnet assemblies are used to securely hold fibers to our V-groove style fiber holders. Please note that two of these fiber clamps are included with each V-groove style fiber holder. We offer these magnetic clamps as replacement parts. They are also useful for customers building customized fiber optic assemblies.

• Accepts Rectangular Fiber Arrays up to 12 mm Wide
• 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.

• Holders for Connectorized Fibers:
  • HFB001: SMA-Connectorized Fibers
  • HFB004: FC/PC-Connectorized Fibers
  • HFB005: FC/APC-Connectorized Fibers
• 12.5 mm Optical Axis Height

These connectorized fiber holders are compatible with the mounting platforms of our multi-axis flexure stages. Each holder is designed to securely hold the center of the connector 12.5 mm (0.49") above the flexure stage platform. The design virtually eliminates fiber tip motion when the fiber cable is moved and significantly improves the repeatability of the positioning of the fiber tip.

• 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.

• Load Capacity: 30 N (6.7 lb)
• Sensitivity: 0.03 N (0.0067 lb)
• Clamps Ø250 µm Jacketed Fibers
• Two Magnetic HFM001 Fiber Clamps Included

This force-sensing cell uses the same principle as the FSC103 Axial Force Sensor sold above, but is used to position a bare optical fiber with respect to another device. 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 available for the actuator controller to indicate that the desired position has been reached.

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

These clamps are used to attach accessories to the grooved top plate of the NanoMax, MicroBlock, or RollerBlock stages.

The AMA010(/M) Cleats have a flat milled along one side. To lock an accessory along the center alignment groove, rotate the cleat so that the flat is facing the accessory, and secure the accessory between two cleats. The cleats can be rotated without needing to remove the locking screws. They are sold in packs of 15, together with 6-32 UNC (M3) locking screws and washers.
