Ø1" and Ø1.5" Posts can be Secured to an Optical Table Using Post Base Adapters and Clamping Forks

Features

  • Convert Ø1" Post Extensions and Ø1.5" Posts into Pedestal-Style Posts
  • All Bases Provide Large Bottom Relief Cuts for Exceptional Stability
  • Clamping Forks Offer Exceptional Positional Mounting Flexibility

Ø1" Post Bases
The BE1(/M) and BE1R(/M) fasten directly to a Ø1" post extension or a Ø1/2" post holder via the provided 1/4"-20 (M6) stud, converting a standard post or post holder into a pedestal-style mount. For additional stability in temporary setups, the BE1R(/M) base provides a high-strength magnet in the base. Ø1" pedestal configurations are directly compatible with our CF038-P5, CF038C(/M)-P5, CF125, CF125C(/M), CF175, and CF175C(/M) solid stainless steel clamping forks, which provide for the greatest overall positional flexibility when mounting to an optical table.

Ø1.5" Post Bases
The PB1 and PB2(/M) fasten directly to a Ø1.5" post via 1/4"-20 (M6) cap screws placed through the bottom-located counterbores in the base. The PB1 offers four top-located 1/4" (M6) counterbores located on 1" centers for compatibility with both imperial and metric optical tables and breadboards. The PB2 provides four 1/4" (M6) counterbored slots for additional positional freedom where alignment on an optical table does not conform to standard table mounting hole spacing.

The PB4 provides even greater positional flexibility by fastening directly to a Ø1.5" post via the provided 1/4"-20 (M6) stud, converting a standard post into a pedestal-style post. This pedestal configuration is directly compatible with the PF175B clamping fork, which provides high positional flexibility when mounting to an optical table.

Clamping Forks: Tip for Maximizing the Holding Force

Clamping force applied by the CL2 clamping fork
Click to Enlarge

Figure 2: More than half the total applied force (FTotal) holds the object, since L1 > L2. The height of the left leg of this CL2 clamp is variable to compensate for the object's height. This allows the clamp's top surface and the mounting surface to be made parallel.**
Clamping force applied by the CLA5 clamping fork
Click to Enlarge

Figure 1: Less than half the total applied force (FTotal) holds the object, since L1 < L2. The clamp illustrated above is the CL5A.

Clamped objects can be fairly easy to move when the torqued screw in the clamp's slot is positioned too far from the object. Correct positioning of the screw protects clamped objects from being knocked out of position.

To maximize the clamping force, position the screw as close as possible to the object.**

This works since clamps like CL5A and CL2 (Figures 1 and 2, respectively) divide the torqued screw's applied force (FTotal) between two points.

Clamping force F2 is applied to the object. The value of F2 is a percentage of FTotal and depends on L1 and L2, as described below. The remainder (F1) of the total force is applied through the opposite end of the clamp.

The following equations can be used to calculate the two applied forces.

Force Applied to
Object:
Force Applied to
Other Contact Point:

These equations show that the clamping force on the object increases as the distance between the object and screw decreases. The force supplied by the torqued screw is evenly divided between F1 and F2 when L1 and L2 are equal.

**Note that maximizing the clamping force also requires both the top surface of the clamp and the area it contacts on the object to be parallel with the mounting surface, as depicted in Figures 1 and 2.

If the tangent at the interface between the clamp and object is not parallel to the mounting surface, the force applied to the object will be divided between pressing it into and pushing it across the mounting surface. The force directed along the mounting surface may, or may not, be sufficient to translate the object.

To accommodate different object heights, clamps like the CL2 have one threaded, variable-length leg, which is shown on the left in Figure 2. The number of threads between the clamp and mounting surface should be adjusted to compensate for the height of the object and to keep the clamp's top surface level with the table.

Optical Tables: Clamping Forks and Distortion of the Table's Surface

Optical table composite construction
Click to Enlarge

Figure 3: The construction of a Nexus table / breadboard includes a (1) top skin, (2) bottom skin, (3) side finishing trim, (4) side panels, and (5) honeycomb core. The stainless steel top and bottom skins are 5 mm thick.

Clamping forks are more rigid than the mounting surface of composite optical tables. It might be expected that the spine of the clamping fork would bend with the force exerted by the screw as the torque is increased. Instead, the screw will pull the skin of the table up and out of flat before the clamping fork deforms. Due to this, clamping forks should be used with care when securing components to optical tables. Clamping arms, which are discussed in the following, are alternatives to clamping forks that are less likely to deform the table's mounting surface.

Optical Table Construction
Optical tables and breadboards with composite construction (Figure 3) are designed to be rigid while providing vibration damping. The 5 mm thick, stainless steel top skin is manufactured to be flat, but a localized force can deform it. When the top skin is deformed, optical components will not sit flat, and optical system alignment and performance can be negatively affected.

Clamping Forks
Standard clamping forks are installed with one edge placed on the table's surface and the opposite edge on the object (Figure 4). Between these two edges, there is clearance between the bottom of the clamp and the surface of the table. This bridge makes it possible to use a single screw to both secure the clamp to the table and exert a holding force on the object.

When the clamp is secured by torqueing the screw, the screw pulls up on the top skin of the table (Figure 5).

As the torque on the screw increases, the top skin of the table rises. Not only does pulling up on the table surface risk permanently damaging the table, this can also disturb the alignment of the optical component the clamp is being used to secure. By lifting the table's skin, the mounting surface under the clamped object tilts.

Clamping arms do not create a bridge over the mounting surface
Click to Enlarge

Figure 6: The POLARIS-CA1/M clamping arm has a slot that accepts a mounting screw, a separate screw that applies a clamping force to an installed post, and identical top and bottom surfaces. Since a nearly continuous track around the surface of the clamping arm is in contact with the mounting surface, clamping arms cause negligible bridging effects.

Click to Enlarge

Figure 5: Torqueing the screw creates a force that pulls up on the table's top skin. The lifted skin tilts the mounting surface and can induce angular deviation of the object. This effect is exaggerated in the above image for illustrative purposes.
Bridge created by clamping fork
Click to Enlarge

Figure 4: A standard clamping fork, such as the CL5A, contacts the table along only one edge. The opposite edge is in contact with the object to be secured. A bridge forms between the two. The screw that applies the clamping force is not shown.

Clamping Arms
Clamping arms, such as the POLARIS-CA1/M, shown in Figure 6, are designed to secure a post while minimally deforming the mounting surface.

The clamping arm in Figure 6 differs from clamping forks in two significant ways. One is the surface area that makes contact with the optical table, which is highlighted in red, and the other is the method used to secure the post.

The area in contact with the optical table makes a nearly continuous loop around the base of the clamp. The contact area is flat and flush with the table when the clamp is installed. The only break in the loop is a narrow slot in the vise used to grip the post. 

This design uses two screws, instead of the clamping fork's single screw. One screw (not shown) secures the clamp to the table, and the other (indicated) is tightened to grip the post. Since one screw is not required to perform both tasks, it is not necessary for this clamping arm to form a bridge between the clamped object and the optical table.

Although the contact area is a loop, and not a solid surface, this clamp causes negligible distortion of the mounting surface. This is due to the open area inside the contact surface being narrow and surrounded by the sides of the clamp, which resist the force pulling up on the table.

Hello, I have a suggestion: a counterbored version of your magnetic pedestal base (BE1R) so that it could be used for both M6 and 1/4"-20 by the user providing the appropriate screw.

Pedestal Base Adapters
The BE1(/M) and BE1R(/M) pedestal base adapters feature a 1/4"-20 (M6)-threaded stud that fit into the bottom of our standard Ø1/2" post holders or Ø1" posts to convert them into pedestal-style mounts for added stability. The BE1R(/M) adapter features a magnet in the base that is sufficiently strong to securely hold the base in place without clamping to an optical table (see photo at the top right). Made from solid 303 stainless steel with a 1.25" (31.8 mm) outer diameter, these adapters allow standard Ø1" posts to be used with the clamping forks sold below.

The BE1(/M) base adapter is available in a pack of five for ease of ordering.

Clamping Forks
These clamping forks are designed to provide exceptional clamping force when used with our Ø1/2" post holders and Ø1" posts that have been adapted using the BE1(/M) or BE1R(/M) to pedestal-style mounts. They can also be used with our pedestal-style Ø1/2" post holders or Ø1" pedestal posts without any need for the BE1(/M) or BE1R(/M).

Fabricated from solid 303 stainless steel, all of these clamping forks create three points of contact with the table for high stability. For flexibility in the positioning of post assemblies, the CF038-P5 and CF038C(/M)-P5 forks offer 0.38" (9.5 mm) long counterbored slots, the CF125 and CF125C(/M) forks offer 1.24" (31.5 mm) long counterbored slots, the CF175 and CF175C forks have 1.75" (44.4 mm) long counterbored slots, and the CF175C/M fork has a 1.76" (44.8 mm) long counterbored slot. The counterbored slots on the CF038-P5, CF125, and CF175 forks are designed for user-supplied 1/4"-20 (M6)-threaded cap screws. For further convenience, the CF038C(/M)-P5, CF125C(/M), and CF175C(/M) forks each include a 1/4"-20 (M6)-threaded captive screw. Please note that significant over tightening of clamping forks can deform the surface of an optical table, which can cause misalignment of components and decrease stability.

Our clamping forks are also available in packages of five for ease of ordering (note: the CF038-P5 and CF038C(/M)-P5 clamping forks are only available in packs of five).

Post Position Retainers

  • Mark the Position of Ø1" and Ø1.5" Posts within an Optical System
  • Realignment Based on Two Contact Points
  • Third Contact Point for Realigning Square Components
  • Swivel Head Retainer Available with 200° of Rotation

Thorlabs' Position Retainers can be used to realign posts that have been removed from an optical system. They act as markers on the breadboard or optical table in the event that you need to remove a post from your setup. The two dots near the ends of the outer arms of the retainer mark the two points of post contact. The third dot, located within the V-groove, is for retaining the position of a square base or other squared-off component. For more information on using our retainers with square components, click here.

The RSPC Fixed Retainer is a compact solution for use with Ø1" and Ø1.5" Pedestal Posts. The post should be independently clamped down before aligning the RSPC retainer. After the retainer is mounted in place, the post can be removed from the setup and then later placed back into the same position.

The RSPCS(/M) Swivel Retainer features a swivel head for 200° of rotational adjustment. This allows for access to additional mounting holes on the breadboard. The post should be independently locked before aligning RSPCS(/M) retainer. Partially loosen the tension adjuster screw and then mount the retainer to a breadboard tap while maintaining contact with the post. Lastly, tighten the tension adjuster screw. After this the component can be removed from the setup and then later placed back into the same position.
