Features

  • Slip Ring Mounts and Clamps for Cylindrical Components
  • Tube Clamps for Easy Installation and Removal
  • Mount SM05, SM1, SM30SM2, and SM3 Lens Tubes
  • Mount Cylindrical Components with Diameters from 0.59" to 3.2" (See Table Below for Available Sizes)

Thorlabs' Slip Rings and Clamps are both designed to enable post mounting of cylindrical components. With slip rings, lens tube systems and other cylindrical components can be mounted by passing them through the clear aperture of the ring and then securing the flexure lock. In contrast, the clamps enable drop-in installation and removal of cylindrical components, as shown in the image to the right. These clamps and slip rings can be attached to any of our Ø1/2" posts or other rigid construction components. They are available to hold SM05-, SM1-, SM30-SM2-, or SM3-threaded lens tubes, or C-Mount extension tubes, as well as cylindrical objects with a variety of other diameters (see table below).

Thorlabs also offers a variety of other fixed mounts, including a series of threaded fixed lens mounts.

A minor suggestion for this page: in your component compatibility table you could add a row for the accepted component diameter in millimeter for convenience.

Hello, thank you for your feedback. We will look into updating the presentation with this information.

These Slip Rings are designed to mount cylindrical components using a flexure mechanism that is actuated with a locking screw. In particular, the SM05RC(/M), SM1RC(/M), SM30RC(/M), SM2RC(/M), and SM3RC(/M) are ideal for mounting SM05-, SM1-, SM30-SM2-, and SM3-threaded lens tubes, respectively. The C05RC(/M), SM087RC(/M), C1RC(/M), and C2RC(/M) are designed to mount cylindrical components with outer diameters of 1/2", 0.865", 1.00", and 2.00", respectively.

The small body design and flat sides of these slip rings make them versatile and easy to integrate into existing systems. The locking screw is conveniently located along the top surface of the mount for easy access. Refer to the table to the right for locking screw hex sizes. These slip rings can easily be mounted to any of our Ø1/2" posts via the bottom-located 8-32 (M4) tap.

  • Drop-In Installation and Removal of Cylindrical Components
  • 3-Point Contact Provides Stable Mounting
  • Hold Outer Diameter of  SM05, SM1, SM30, SM2, or SM3 Lens Tubes as well as C-Mount Extension Tubes
  • Mount Ø0.59", Ø1.27", Ø1.50", and Ø1.74" Cylindrical Components

These clamps are designed to enable easy installation and removal of cylindrical components from optical systems. In particular, the SM05TC, SM1TC, SM30TC, SM2TC, and SM3TC are ideal for mounting SM05-, SM1-, SM30-SM2-, and SM3-threaded lens tubes, respectively. The C127TC, C15TC, and C174TC are designed to mount cylindrical components with outer diameters of 1.27", 1.50", and 1.74", respectively. The C059TC is designed to hold our Multimode Fiber Optic Rotary Joint and our Optogenetic Rotary Patch Cables. To remove a cylindrical component, simply unscrew the locking screw, flip the mount open, and lift the tube straight up and out. This feature is useful for users who do not have the room to slide the entire component out of a mount due to tight space constraints.

This series of clamps can easily be mounted to any of our posts using the #8 (M4) counterbore on the bottom of the clamp. The SM05TC can also be secured to a mini-series post via a #4 washer and 4-40 cap screw (not included).
