C15QR(/M) Quick-Release Handle Being Used in Place of the 1/4"-20 (M6) Clamping Screw

Features

  • Mounting Clamp for Ø1" RS-Series Posts
  • 2" x 2" (50.8 mm x 50.8 mm) Mounting Plate
  • 1/4"-20 (M6) Tapped Holes (Qty. 24)
  • 8-32 (M4) Tapped Holes (Qty. 25)

The C1001 Ø1" Post Mounting Clamps are an integral part of our Ø1" Post Assemblies, providing rigid, general-purpose mounting surfaces. These mounting clamps 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 a 3/16" (5 mm) hex key or balldriver.

The C1001 offers a removable 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.

A quick-release handle is also available that allows for a simple and reliable way of securing the C1001 Post Mounting Clamp to a post. It is easily installed by replacing the 1/4"-20 (M6) locking screw in the post clamp. The 2.03" (51.4 mm) long handle contains a 1/4"-20 (M6) threaded stud that engages the part by simply rotating the handle.

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.

Quick-Release Handle

Left: Handle Being Attached to the Former Generation C1501 Post Mounting Clamp
Right: Pull Back to Rotate the Position of the Handle
  • Quick-Release Handle for Fast and Repeated Positioning of Post Clamps
  • Compatible with Ø1" (Ø25.0 mm) or Ø1.5" Post Clamps that Incorporate a 1/4"-20 (M6) Clamping Screw
  • Provides More Control and Feel when Locking and Unlocking a Clamp
  • Handle can be Rotated Without Actuating the Locking Screw
  • 1/4"-20 (M6) Threads

The C15QR(/M) Quick-Release Handle provides a simple and reliable way of securing a flexure-based Ø1" (Ø25.0 mm) or Ø1.5" post clamp. In many cases a cap screw is used to lock a flexure-based clamp in place on a post, which requires a balldriver for adjustments. Depending on the mounted load, using a balldriver can be difficult, or even unsafe. This quick-release handle mitigates this problem by allowing the clamp to be hand-tightened, ensuring better control over the amount of torque applied to tighten or loosen the clamp. This also decreases the amount of time needed for basic setup and alignment by eliminating the need for additional balldrivers and allowing for a quick way to secure a clamp.

Easily installed by replacing the 1/4"-20 (M6) locking screw in a post clamp, the 2.03" (51.4 mm) long handle contains a 1/4"-20 (M6) threaded stud that engages a part by rotating the handle. Once the handle is tightened to secure a clamp to a post, the internal ratchet-type mechanism allows for the handle's rotational position to be adjusted without actuating the mounting stud. Simply pull the handle outwards to disengage it from the mounting stud, as shown in the image to the right, then rotate it to a more convenient position. This feature ensures that the handle will always be accessible to the user.
