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 free-space subsystem.

Figure 1: Vernier scale measuring 76.0
Click to Enlarge

Figure 1: An example of how to read a vernier scale. The red arrow indicates what is known as the pointer. Since the tick mark labeled 10 on the vernier scale aligns with one of the tick marks on the main scale, this vernier scale is reading 75.60 (in whatever units the tool measures).

Reading a Vernier Scale

Vernier scales are typically used to add precision to standard, evenly divided scales (such as the scale on Thorlabs' rotation mounts). A vernier scale has found common use in many precision measurement tools, the most common being calipers and micrometers. The direct vernier scale uses two scales side-by-side: the main scale and the vernier scale. The vernier scale has a slightly smaller spacing between its tick marks (10% smaller than the main). Hence, the lines on the main scale will not line up with all the lines on the vernier scale. Only one line from the vernier scale will match well with one line of the main scale, and that is the trick to reading a vernier scale.

Figures 1 through 3 show a vernier scale system for three different situations. In each case, the scale on the left is the main scale, while the small scale on the right is the vernier scale. When reading a vernier scale, the main scale is used for the gross number, and the vernier scale gives the precision value. In this manner, a standard ruler or micrometer can become a precision tool.

The 0 on the vernier scale is the "pointer" (marked by a red arrow in Figs. 1 - 3) and will indicate the main scale reading. In Figure 1 we see the pointer is lined up directly with the 75.6 line. Notice that the only other vernier scale tick mark that lines up well with the main scale is 10. Since the vernier 0 lines up with the main scale’s 75.6, the reading from Figure 1 is 75.60 (in whatever units the tool measures in).

That is essentially all there is to reading a vernier scale. It's a very straightforward way of increasing the precision of a measurement tool. To expound, let’s look at Figure 2. Here we see that the pointer is no longer aligned with a scale line, instead it is slightly above 75.6, but below 75.7; thus the gross measurement is 75.6. The first vernier line that coincides with a main scale line is the 5, shown with a blue arrow. The vernier scale gives the final digit of precision; since the 5 is aligned to the main scale, the precision measurement for Figure 2 is 75.65.

Since the vernier scale is 10% smaller than the main scale, moving 1/10 of the main scale will align the next vernier marking. This asks the obvious question: what if the measurement is within the 1/10 precision of the vernier scale? Figure 3 shows just this. Again, the pointer line is in between 75.6 and 75.7, yielding the gross measurement of 75.6. If we look closely, we see that the vernier 7 (marked with a blue arrow) is very closely aligned to the main scale, giving a precision measurement of 75.67. However, the vernier 7 is very slightly above the main scale mark, and we can see that the vernier 8 (directly above 7) is slightly below its corresponding main scale mark. Hence, the scale on Figure 3 could be read as 75.673 ± 0.002. A reading error of about 0.002 would be appropriate for this tool.

As we've seen here, vernier scales add precision to a standard scale measurement. While it takes a bit of getting used to, with a little practice, reading these scales is fairly straightforward. All vernier scales, direct or retrograde, are read in the same fashion.

Hello, I have a question about FBTP. Let me inform what are the maximum and minimum thickness of which a plate can be mounted. I'd like to mount a 1.05 mm thick plate object, is it possible?
llamb  (posted 2019-12-03 10:24:44.0)
Thank you for your feedback. Since the FBTP requires epoxy to mount a plate optic, there is no minimum thickness requirement. The slot is manufactured to a minimum width of 1.092 mm, so we would recommend 1.09 mm as a very maximum thickness. Your 1.05 mm thick plate will indeed fit.

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? Photo of the system into which we want to add the shutter: https://drhotdog.smugmug.com/Other/Laser-comb/n-nj2wRX/i-sRGGrj3/A (the output is on the right)

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.

Kinematic Tip/Tilt and Rotation Mounts

Kinematic FiberBench Mount Features
  • 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.

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.

  • Quick-Release Snap-In Flexure Mechanism for Integration Into 30 mm Cage Systems
  • Post Mountable via 8-32 (M4) Tap

This 30 mm Cage System Mount for FiberBench Components allows integration of our line of FiberBench Components with our 30 mm cage system. It includes two through holes that fit the dowel pins on our FiberBench optic mounts. Once the dowels have been inserted, they can be locked in position using a 0.035" balldriver or hex key to tighten the setscrew on the front face of the mount.

The mount includes two snap-in flexure clamps for attaching our Ø6 mm cage rods, which can be locked with a 5/64" (2.0 mm) hex key. This snap-in feature allows components to be easily inserted and removed without disassembling the entire cage system. When this mount is used in a cage system that is attached to a FiberBench with the HCA3-CP cage plate, the beam height for all optical components is the same. An 8-32 (M4) tapped hole on the bottom of the CPFB mount can be used to secure it to a Ø1/2" post. Please note that this cage system mount cannot be used with FiberBench optic mounts that are more than 0.75" (19.1 mm) wide in the direction perpendicular to the optical axis.
