Accessory Mounting Posts for ScienceDesk™ Workstations

• Two Lengths: 750 mm (29.5") or 1000 mm (39.4")
• Ideal for Monitor Mount, Overhead Shelves, or Instrument Shelves
• M16 Bolt Attaches to Outside Rails of ScienceDesk Frame

These 750 mm (29.5") and 1000 mm (39.4") tall posts are used to attach ScienceDesk™ accessories, such as our Monitor Mount, Overhead Shelves, or Instrument Shelves, to the frame of our ScienceDesk Workstations. Each post has a diameter of 1.5", making them compatible with our Ø1.5" post platforms, mounting plates, construction accessories, and V-mounts. A provided M16 bolt is used to attach the post to the frame of the ScienceDesk.

We offer the TA2 Post Adapter below for mounting these posts onto the optical table or breadboard surface. 

The TA2 Post Adapter allows a Ø1.5" ScienceDesk post to be fitted to an optical table or breadboard. With this adapter, post-mounted ScienceDesk accessories such as monitor mounts, keyboard rests, and shelves can compliment nearly any standard breadboard or table, increasing usable workspace.

The adapter features elongated slots and is supplied with a replacement post stud, together with M6 and 1/4"-20 bolts to fit to either metric or imperial work surfaces. Two adapters are necessary to attach the two posts required for fitting an overhead shelf unit. The adapter is fitted to the ScienceDesk posts via an M16 counterbore.

The BD8A and DP14A Feature an Engraved Top Cap Indicating the Item # as well as a 1/4"-20 Tapped Hole

• Dynamic Damping Provides Fast Ring Down
• Nickel-Plated Steel with Matte Finish for Long Life
• Permanent Mounting Base with Four 1/4" (M6) Counterbores
• 8" and 14" Long Versions Available

These dynamically damped Ø1.5" mounting posts provide a vibration-limiting alternative to using a Ø1.5" mounting post with a TA2 adapter. These posts feature optimized damping that outperforms other damped post designs. Damped posts are ideal for use in applications where vibrations must be limited, such as beam steering and imaging. Ring down testing was performed on both of these posts. The results for the DP8A are shown below, for DP14A results and information about the testing click here.

A 1.1 lb (0.50 kg) load was mounted approximately 2" from the top of the Post. The post was then struck approximately 0.5" from the top with an impulse hammer, oscillations were measured with an accelerometer mounted to the top of the post, and the time for the amplitude to return to 0 was noted. For complete test results please click here.

Our Dynamically Damped Posts are fabricated from steel with a nickel-plated matte finish and utilize internal damping weights containing no lead. They have an engineered passive vibration dampening design. An internal suspension system allows weights inside the post to move independently from the post's outer body, thus allowing vibrational energy to quickly be absorbed and dissipated. The permanently attached mounting base has four 1/4" (M6) counterbores, appropriately spaced for securing it to breadboards with taps on 1.00" (25.0 mm) centers. The top cap is engraved with the part number for identification. The posts also feature a top-located 1/4"-20 (M6) tapped hole to allow components to be secured to the top of the post.

Locking Clamp Positioned Under Our PSY321 Breadboard Mounting Bracket, Holding it in Place and Allowing for Free Rotation of the Bracket

• Retain the Position of Ø1.5" Post Mounted Accessories
• Hinged Clamp Design Allows for Installation Without Removing Existing Shelves

Thorlabs PSY322 Hinged Locking Clamps are the ideal solution for preventing the unwanted movement of accessories along the axis of the post. Locking the clamp in place (5 mm hex key included) directly under a post-mounted accessory, as shown to the right, prevents the accessory from sliding down the post when it is loosened for adjustments. This also allows mounted shelving or brackets to be freely rotated around the axis of the post to a needed position at any time.
