The Pillar Post series is ideal for enhancing our fixed height riser supports. By combining the rigidity of these solid Ø1" posts with our high stability RB2 base (see below), any arbitrary height support structure can be constructed. Each post is machined with a 1/4"-20 tapped hole in both ends for direct mounting to an optical table or standard base and an optical mount. These posts are machined from nonmagnetic 303 stainless steel.

Each Imperial Pillar Post is shipped with an AE8E25E adapter. This adapter has external 1/4"-20 threading and internal 8-32 threading. The adapter can be used with an 8-32 setscrew to attach many of Thorlabs' imperial optomechanical parts to a Ø1" imperial pillar post. In principle, the adapter can also be used to connect two Pillar Posts, but a solid 1/4"-20 setscrew, which is included in our HW-KIT4 hardware kit, is a more stable choice for this.

The Pillar Post series is ideal for enhancing our fixed height riser supports. By combining the rigidity of these solid Ø25.0 mm posts with our high stability RB2 base (see below), any arbitrary height support structure can be constructed. Each post is machined with an M6 tapped hole in both ends for direct mounting to an optical table or standard base and an optical mount. These posts are machined from nonmagnetic 303 stainless steel.

Each Metric Pillar Post is shipped with an AE4M6M adapter. This adapter has external M6 threading and internal M4 threading. The adapter can be used with an M4 setscrew to attach many of Thorlabs' metric optomechanical parts to a Ø25.0 mm metric pillar post. In principle that adapter can also be used to connect two Pillar Posts but a solid M6 setscrew as included in the hardware kit HW-KIT4/M will provide a more stable solution.

• Solid Stainless Steel Construction
• 1/4" (M6) Clearance Hole
• Large Diameter Relief Cut on Top and Bottom for Additional Mounting Stability

These spacers are designed for achieving "in between" heights of our RS-Series Pillar Posts without compromising structural rigidity. The center 1/4" (M6) clearance hole allows threaded studs to pass through to the mating tap of the components on either side of the spacer. Achieving, for example, a total post height of 8.2" is as simple as inserting one RS5M spacer (0.2" thickness) in between two RS4 posts (4" length).

Included with each spacer are two hex-driven set screws. The 1 mm through 5 mm spacers include an M6 x 20 mm setscrew and a 1/4"-20 x 7/8" setscrew; alternatively, the 6 mm through the 10 mm spacers include an M6 x 25 mm setscrew and a 1/4"-20 x 1" setscrew.

• Peel Away Individual Layers as Needed
• Stainless Steel
• Tabbed for Easy Peeling
• Sold in Packs of 5

This Ø25 mm, peelable, laminated shim provides fine height adjustment when using our Ø1" posts. These 1.0 mm ± 10% thick shims come in packs of 5 and have 14 layers, which are each 0.075 mm thick. They have a through hole to accommodate a 1/4"-20 (M6) screw.

Be aware the finish on some shims may appear tarnished due to the manufacturing process. This does not affect form, fit, or function. Only the appearance is altered.

To peel, take a sharp edge like an exacto knife or a box cutter and hold it at a 45° angle to the tab on the shim as shown in the photo to the left. Gently flick the knife upward until the layer begins to lift. In general, you should be able to lift an edge within 5 attempts. If you cannot get an edge to lift, gently tap the corner of the tab on a table until the material begins to flare.

Once an edge is lifted, insert the blade under the layer, squeeze the layer between your thumb and the blade, and roll your wrist down and then up to start peeling (see photo in the upper left). Once the layer has been peeled up enough, you can use your thumb and forefinger to remove it the rest of the way. Repeat this process until you have removed as many layers as desired. Discard all peeled-off layers.

The BE1 can be used to Convert a Post Holder into a Pedestal-Style Mount
(Click to Enlarge)

• Combine BE1 Adapter Converts Standard PH Series Post Holder into Pedestal-Style Mount
• Clamping Fork Secures Pedestal-Style Mount to a Breadboard or Table
• Two Sizes: CF125 (1.25" Counterbored Slot) and CF175 (1.75" Counterbored Slot)
• Swivel Fork ±360° to Pick Up Most Convenient Mounting Hole

Pedestal Base Adapter
The BE1 fastens to the base of our standard PH Series Post Holders (as shown to the right) and RS Series Ø1" Pillar Posts to convert them into Pedestal-Style mounts. This combination provides a high degree of mounting flexibility. Note: Together, the BE1 Base Adapter and PH Series Post Holder provide nearly the same design to that of the PHxE Series Pedestal-Style Post Holder without the magnets in the base and through hole design.

Clamping Forks
Our solid stainless steel clamping forks are designed to provide exceptional clamping force when used with our pedestal-style posts and post holders. Use a 1/4"-20 (M6) cap screw and washer combination to lock down the base/fork combination. Please note that significant overtightening of clamping forks can deform the surface of an optical table, which can cause misalignment of components.
