Mounts for C-Mount Extension Tubes
Compact Slip Ring
30 mm Cage Plate
Threaded OD Adapter
This slip ring is designed to mount preassembled C-Mount extension tube systems by passing the tube through the mounting ring and securing it with a locking screw. The locking screw is conveniently located along the top surface of the mount for easy access. The slip ring can easily be mounted to any of our Ø1/2" posts via the bottom-located 8-32 (M4) tap. We also offer slip rings for our Ø1/2", Ø2", and Ø3" lens tube systems.
This lens tube clamp is designed to enable easy installation and removal of C-Mount extension tubes from optical systems. To remove an extension tube, simply unscrew the 3/32" (2.5 mm) hex clamping screw, flip the mount open, and lift the tube straight up and out. This feature is useful for users who, because of tight space constraints, do not have the room to slide the entire extension tube out of a mount. The clamp can easily be mounted to any of our posts using the #8 (M4) counterbore on the bottom of the clamp. We also offer clamps for our Ø1/2", Ø2", and Ø3" lens tube systems.
The CP36 cage plate is designed to allow our SM1 Lens Tubes or C-Mount Extension Tubes to slide into the cage plate and be locked in position with a nylon-tipped 8-32 setscrew. This is ideal for situations where it is not desirable to thread the lens tube into one of our threaded cage plates. It will also allow our Ø1.2" free-space isolator packages to be integrated into a 30 mm cage system. A double-bore design gives three points of contact for stable and secure mounting. Each cage rod through hole is accompanied by a side-located locking M4 setscrew, which can be secured using a 5/64" (2 mm) hex key or balldriver.
Please note that this cage plate does not feature a tapped mounting hole, unlike many of our other cage plates. Due to the bore size, there would be interference between the threaded stud on our Ø1/2" posts and the clear aperture of the bore. Therefore, this cage plate cannot be used directly with Ø1/2" Posts, and a cage system utilizing this plate must be supported using a different method. For a post-mountable solution, consider our SM1RC or SM1TC lens tube clamps, but note that these parts are not cage compatible.

The SM2A21 Mounting Adapter allows SM1 Lens Tubes or C-Mount Extension Tubes to be installed within SM2 Lens Tubes or Ø2" optic mounts. The adapter is also compatible with our BE052 Series Beam Expanders. The outer ring surface features external SM2 (2.035"-40) threads that are 0.16" (4.1 mm) long, allowing the adapter to be used with our SM2 Lens Tubes or SM2-threaded mounts, such as the LMR2. The outer surface of the adapter also has a smooth section, measuring 0.31" (7.9 mm) in length, that can be used to secure it in a Ø2" optics mount with a smooth bore such as the KM200. The lens tube or BE052 Series Beam Expander is secured using a nylon-tipped 5/64" (2 mm) hex setscrew.
