Thorlabs offers several component modules that can be used to mount numerous precision optical components. These modules can then be easily integrated into a FiberBench system, and position optics at a consistent beam height of 0.56" (14.2 mm). In each case, the module is designed with two steel dowel pins on its underside that fit into the receiving holes on the FiberBench. Once inserted, the design of the mount ensures that the optic will be at the appropriate height for use within the fiber-optic system.

(posted 2017-05-30 15:40:08.097) FiberBench/FiberPort compatible diaphragm shutter?
We have a optical system supplied by a 3rd party vendor and we'd like to add a diaphragm shutter to the output. The output is via a PAFA-X-4-A FiberPort mounted on a HCA3 end plate on the end of an FT-51X76 FiberBench. Unfortunately there don't seem to be any FibreBench/FibrePort compatible diaphragm shutters. The SHB025 1/4" shutter seems almost ideal, except it is slightly larger than the aperture in the HCA3 and there are no adaptors for attaching it to the FiberBench. Is there a solution using existing parts, or plans to introduce one?

(posted 2016-11-25 16:59:04.833) Hello. I have a question about Kinematic FiberBench Tip/Tilt Rotation Mount for 12.7 mm × 1 mm (W × T) Plate Optics. I'd like to purchase the product for longpass(or shortpass) dichroic mirror mounting.(e.g. DMLP950R) I am using a fiber-bench with two inputs(976nm, and 500-700 nm) and one output, which is a T-shape fiber-bench system, and I want to install DMLP950R into it using this rotation mount. I think the thickness of DMLP950R is suitable to be installed (1mm), but H x W is 36 x 25 mm, which is larger than 12. 7mm. However, I think if the mirror is installed although the mirror size is larger than 12.7mm, I'd like to buy it. Can you advise about this issue? Thanks. tfrisch
(posted 2016-11-30 10:11:04.0) Hello, thank you for contacting Thorlabs. We can offer custom sizes of dichroic mirrors that will fit in our FiberBench compatible mounts. Our Tech Support staff will contact you directly with a quote. |

Zoom- Use for 5 mm Cube or 1 mm Thick Plate Optics
- ±3° Tip/Tilt Adjustment via Three M2.5 x 0.2 Precision Adjusters
- 360° Continuous Rotation with ±12° Fine Adjustment
- Four Locking Collars and a Spanner Wrench are Included
- Additional Locking Collars Available Separately
- Please Contact Tech Support for Custom Mounting Options
These tip/tilt rotation FiberBench mounts are designed to mount either 5 mm cube optics, such as polarizing or non-polarizing beamsplitter cubes, (Item # FBTC) or 1 mm thick plate optics up to 12.7 mm (0.5") wide, such as beamsplitters or mirrors, (Item # FBTP) while maintaining the appropriate beam height. Both versions require epoxy to mount optical components. The circular rotation plate can be rotated a full 360° and is engraved with a scale marked every 5°. Additionally, a Vernier scale provides 1° resolution for fine rotation. These mounts do not suffer from left/right handedness restrictions, and thus can be used in any orientation on a FiberBench.
An engraved dot is present on the FBTP Plate Optic Mount between the 0° and 90° engravings. Beamsplitter optics should be installed with the beamsplitter coating facing this dot. This allows an incident beam to be aligned so that it is split at the center of the mount.
These mounts allow for tip, tilt, and rotational adjustment for precision beam alignment and steering control. Three screws control the tip/tilt of the mount (see Figure 1), yielding up to ±3° of adjustment. Additionally, these screws can also provide some vertical adjustment when all three screws are rotated by the same amount. A physical stop prevents the tip/tilt springs from being overextended. When engaged, the fine rotation adjustment screw (see Figure 1) gives up to ±12° adjustment. All adjustment screws use a 0.05" hex key, which is included with these mounts. Furthermore, they can be locked into position (see Figure 2) with a spanner wrench to prevent accidental movement. The necessary spanner wrench (SPW403) is included; simply insert the included hex key through the spanner wrench, and while holding the adjustment screw static, use the spanner wrench to tighten the locking nut (see Figure 3).
Additional locking collars and spanner wrenches are also available for purchase separately. If desired, two locking collars can be used together to create a hard stop (see Figure 4). Alternatively, a single collar can be epoxied to an adjuster using our G14250 epoxy to create a permanent hard stop.
We also offer post-mountable versions of these mounts with 8-32 (M4) taps for general mounting of optics on Ø1/2" Posts.

- Adapter Plate Mounts an EO Modulator in the Beam Path
- 4 Tapped Holes for Mounting the Modulator (Screws Included)
- Alignment Pins for Mounting to any FiberBench Over 70 mm Long
- Mounting Screws Included
The FT-EOMA is a mounting bracket used to mount an Electro-Optic (EO) Modulator onto a FiberBench. The length of the bench needs to be at least 70 mm in the direction you wish to mount the modulator. Incorporation of the optional EO Modulator optic mount and polarizer (EO-GTH5M) will require a longer FiberBench. The Linear Polarizer modules are well suited for use with an EO Modulator in a FiberBench System. The application picture to the right shows an EO Modulator with an FT-38X100 Multi-Axis FiberBench, one PCB Linear Polarizer, and two PAF FiberPorts.

- Mounts to the Edge of Thorlabs' FiberBenches
- HCA3-CP is Compatible with Thorlabs' 16 mm and 30 mm Cage Systems
- HCA3-SM05 has 4-40 Taps to Accept Cage Rods from Thorlabs' 16 mm Cage System
- SM05 (0.535"-40) Thread for Compatibility with Ø1/2" Lens Tubes
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.
