Lens Tube Mount Specifications

  Slimmer Body Size to Conserve Space
  Flat Sides for Ease in Use of Multiple Occurrences
  Slip Rings to Mount Ø1/2", Ø1", Ø2", and Ø3" Lens Tubes to 1/2" Posts

These new and improved slip rings are designed to mount preassembled optical lens tube systems by passing the lens tube through the mounting ring and securing it with a locking screw. Their small body design and flat sides make these parts more versatile than the old SMR*C series slip rings. The locking screw is conveniently located along the top surface of the mount for easy access. The SM slip rings can easily be mounted to any of our posts using the 8-32 (M4) mounting hole on the bottom of each slip ring.

  Drop-In Installation and Removal of Lens Tubes
  3-Point Contact When Mounted
  Standard Lens Tube Sizes: Ø1/2" (SM05), Ø1" (SM1), Ø2" (SM2), and Ø3" (SM3)

These lens tube clamps are designed to enable easy installation and removal of lens tubes from optical systems. To remove a lens tube, simply unscrew the 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 lens tube out of a mount.

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

• Ø1.2" Bore Supports Outside Diameter of SM1 Lens Tubes
• Compatible with 30 mm Cage Systems
• Nylon-Tipped Setscrew and Double Bore Securely Hold Lens Tubes
• Not Post Mountable

The CP12 cage plate is desinged to allow our SM1 Lens Tubes to slide into the cage plate and be locked in position with a nylon-tipped 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.

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.

• Ø2.2" Bore Supports Outside Diameter of SM2 Lens Tubes
• Compatible with 60 mm Cage Systems
• Nylon-Tipped Setscrew and Double Bore Securely Hold Lens Tubes
• Not Post Mountable

The LCP09 Cage Plate is designed to allow our SM2 lens tubes to slide into the cage plate and be locked in position with a nylon-tipped setscrew. This cage plate is ideal for situations where it is not desirable to thread the lens tube into one of our threaded cage plates. A double-bore design gives three points of contact for stable and secure mounting.

Please note that this 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.

• Ø1.2" Smooth Central Bore Accepts SM1 Lens Tubes and BE052 Series Beam Expanders
• Compatible with Mounts for Ø2" Optics
• Nylon-Tipped Setscrew to Hold Housing

The SM2A21 Mounting Adapter fits Ø2" optic mounts. The adapter was designed for the BE052 Series Beam Expanders but is also compatible with Thorlabs' SM1 Lens Tubes. The outer ring surface features 0.16" wide SM2 (2.035"-40) external threading, allowing the adapter to be used with SM2-threaded mounts, such as the LMR2. The outer surface of the adapter also has a smooth section, measuring 0.31" in width, that can be used to secure it in a Ø2" optics mount with a smooth bore such as the KM200.

  Compatible with the SM1 and SM2-Series Lens Tubes
  Build Compact 3D Structures
  Easy Assembly of Extended Structures

These building blocks are compatible with our SM1 and SM2-Series Lens Tubes. These precision machined components (square and parallel to better than 0.002") can be used in conjunction with our extensive line of SM1- or SM2-threaded components.

  Mounting Plates for Ø1" and Ø2" Lens Tubes (SM1 and SM2)
  Lens Tube Threads for Rigid Mounting

These right angle brackets have threaded clear apertures and are rigid mounting structures that can be used directly within the beam path. Precision machining with the six surfaces from one solid extruded shape provides maximum rigidity, with parallelism and perpendicularity within 0.002" (0.05 mm).
