Features

  • Mounting Clamp for Ø1" RS-Series Posts
  • 2" x 2" (50.8 mm x 50.8 mm) Mounting Plate
  • Array of Mounting Holes
    • 1/4"-20 (M6) Tapped Holes (Qty. 8)
    • 8-32 (M4) Tapped Holes (Qty. 37)
    • #8 (M4) Counterbores (Qty. 4)
  • Quick-Release Handle Included

The C1011(/M) Ø1" Post Mounting Clamp is an integral part of our Ø1" Post Assemblies, providing a rigid, general-purpose mounting surface. This mounting clamp can be used for fastening our wide array of Optomechanical Mounts in much the same way breadboards are commonly used.

The clamping mechanism is directly compatible with our Ø1" RS-Series Posts. Vertical positioning is achieved by sliding the rear clamping mechanism along the length of the Ø1" post. Once the desired vertical position is achieved, the clamping mechanism is actuated with the included quick-release handle. The 1.44" (36.5 mm) long handle contains a 1/4"-20 (M6) threaded stud that engages the part by simply rotating the handle.

This post clamp offers a front plate, held in place with four 8-32 (M4) cap screws, that provides an array of 1/4"-20 (M6) and 8-32 (M4) tapped holes and #8 (M4) counterbores. Removing the front plate exposes a blank surface that can be used for custom mounting designs.

Would RM1B clamp fit under C1001 and allow C1001 to rotate freely on top of the clamp? Wondering if the clamp would interfere with the plate or the quick release handle.

Thank you for your feedback. No, the RM1B clamp would not allow the C1001 to rotate freely on top of it. When the RM1B is mounted flush underneath the Ø1" post clamp of the C1001, there can be about <30° of rotational freedom before the extended mounting plate of the C1001 interferes with the RM1B.

I had to build systems with this part (C1001), and the problem is, it would be great if some of the holes in the matrix were counterbore. Because it would allow ultra-rigid locking of optical mounts like the KC1-T without any intermediate pillar or plate, without the random angle that you have with a headless screw. Basically, when I had to use this part, I machined a custom matrix plate with couterbore holes myself!

Response from Chris at Thorlabs: Thank you for your inquiry. I'm not sure how useful it would be though to have couterbores on the C1001. You would need to remove the front plate to mount anything, and would need to have it at the correct angle before putting it back on the post mounted back piece. If you are mounting only one item with an 8-32 tap, perhaps it would be more useful to use something like the RM1A or RM1C, each found here. The RM1A has a counterbore for an 8-32 cap screw. The RM1C has a rotating 8-32 threaded piece to allow for adjustment while mounted. http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=2012

Instead of the mounting plate with all the holes, would an angle bracket like the AP90 be possible for this mount? I could see it being useful for mounting small instrument shelves for low-weight applications.

Response From Chris at Thorlabs: Thank you for your feedback. At this time, there is no way to mount an angle bracket like the AP90 to the C1001. The slot size is too wide for the current mounting holes, so a new bracket would need to be introduced. I will see if we can add this to our product line, but in the meantime, if you would be able to use the 1.5" posts series, the C1505 seems to match your description pretty well.

Response from Tim at Thorlabs: Thank you for your feedback! In much the same way a breadboard provides a general mounting surface, the C1001 provides this feature utilizing our 1" diameter posts. They were designed, with a large array of ¼”-20 and 8-32 tapped mounting holes, to allow versatility to adapt to the user's mounting needs.
