SM1 Lens Tube Compatible Cage Plates




  • Integrate SM1 Lens Tubes with 30 mm Cage System
  • Version with Ø1.2" Bore for Slide-In Lens Tube Mounting

Features

  • Integrate SM1 Series Lens Tubes with 30 mm Cage Systems
  • Compatible with ER Series Cage Construction Rods

SM1-Threaded (1.035"-40) cage plates and cage cubes allow SM1 Lens Tubes to be integrated into 30 mm Cage Systems by threading the lens tube into the plate. Alternatively, the CP12 cage plate has a Ø1.2" bore through the part, which allows an SM1 lens tube to be slid into it and then locked in place.


SM1-Threaded Cage Plates, Post Mountable

  • Directly Mounts Optical Components Within a 30 mm Cage System Assembly
  • 2 Thicknesses Available: 0.35" and 0.5"
  • Tapped with Our Standard SM1 Thread (1.035"-40)
  • Post Mountable via 8-32 (M4) Tapped Hole

The CP02(/M) is 0.35" thick and provides a center-located SM1 (1.035"-40) threaded bore that is compatible with our popular Ø1" lens tubes. The center-threaded bore of the CP02(/M) can also directly accept a Ø1" optic up to 0.2" (5 mm) thick. Two SM1RR retaining rings are included. Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key.

The CP02T(/M) is 0.5" thick, and allows two cage assemblies to be joined end-to-end. The extra thickness and double locking 4-40 setscrews enable two extension rods to be inserted and firmly locked into place, allowing for a rigid connection of two cage system subassemblies. The center-located SM1 (1.035"-40") tapped hole directly accepts Ø1" optics up to 0.35" (8.89 mm) thick. Two SM1RR retaining rings are included.

 

SM1-Threaded 30 mm Cage Plate, Not Post Mountable

  • Directly Mounts Optical Components Within a 30 mm Cage System Assembly
  • 3 Thicknesses Available: 4 mm, 6 mm, and 8 mm
  • Tapped with Our Standard SM1 Thread (1.035"-40)
  • Not Post Mountable

At 4 mm, 6 mm, and 8 mm thick, respectively, the CP4S, CP6S, and CP8S are the thinnest cage plates we offer. They have a center-located SM1 (1.035"-40) threaded bore that is compatible with our SM1 threaded optomechanical components. These plates allow the close spacing of optical components within a cage system. Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key. Unlike the CP02(/M) and the CP02T(/M) sold above, these cage plates do not offer an 8-32 (M4) tapped hole for post mounting.

 

SM1-Threaded 30 mm Cage Plate with Enhanced Clamping

  • Directly Mounts Bulk Optics Within a 30 mm Cage System Assembly
  • Tapped with Our Standard SM1 Thread (1.035"-40)
  • Post Mountable Via 8-32 (M4) Tapped Hole
  • Thickness: 0.35"

The CP08(/M) improves upon the popular CP02(/M) design providing the same center-located SM1 (1.035"-40) threaded bore and 8-32 (M4) mounting hole, but a more stable clamping mechanism for our standard ER rods. This cage plate uses an enhanced clamping mechanism that increases the surface area in contact with the ER rods. The CP08(/M) uses four side-located 4-40 (M3) cap screws for securing the ER rods. The center-threaded bore of the CP08(/M) can also directly accept a Ø1" optic up to 0.2" (5 mm) thick just like the CP02(/M). One SM1RR retaining ring is included.

 

30 mm Cage Plate with Ø1.2" Bore

  • 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. Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key.

 

Ø2" Round Cage Plates (30 mm Cage and SM1 Compatible)

  • Compatible with 30 mm Cage Systems
  • CP07 Offers SM1 (1.035"-40) Internal Threading and Smooth Ø2" Outer Diameter
  • CP07T Offers SM1 (1.035"-40) Internal Threading and SM2 (2.035"-40) External Threads
  • Ideal for Mounting Cage Assemblies in Optomechanical Mounts Designed for Ø2" Optics
  • Not Post Mountable

 

The CP07 and CP07T are ideal for mounting small cage subassemblies into optomechanical mounts designed for Ø2" optics (such as our KS2 Ø2" kinematic mirror mount) or SM2-series threads (such as our SM2-series lens tubes). Both plates feature an SM1 (1.035"-40) tapped hole for mounting Ø1" optics up to 0.2" (5 mm) thick. Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key. One SM1RR retaining ring is included. Pictured to the right is the CP07T cage plate being used in a 4-axis alignment system that can be used with laser diode modules and fiber collimators.

The CP07 has a smooth Ø2" outer diameter, which works well with Ø2" mounts with a setscrew, while the CP07T has SM2 (2.035"-40)

 

30 mm Cage to Ø1/2" Post Adapters

  • Mounts Ø1/2" TR Post and Components in a 30 mm Cage System
  • Double-Bored Hole and Locking Thumbscrew Securely Locks Post in Position
  • CP02(/M) Cage-Plate-Style Front Face with SM1-Threaded Through-Hole

 

Thorlabs' 30 mm cage to Ø1/2" post adapters allow the integration of our post-mounted components into our 30 mm cage system. The front face of this clamp is similar to the CP02(/M) cage plate and accommodates our Ø6 mm ER cage rods which are secured using the side-located locking setscews and are 30 mm apart. The center-located SM1 (1.035"-40) threaded bore, which is compatible with our popular Ø1" lens tubes, directly accepts a Ø1" optic up to 0.19" (4.8 mm) thick. Two SM1RR retaining rings are included.

The tail stock of this adapter has a double-bored through-hole and a spring-loaded thumbscrew that provide three-point contact for Ø1/2" posts for secure placement. Two versions are available, providing either 10 mm [CPTR10(/M)] or 20 mm [CPTR20(/M)] separation between the post center and the back of the cage plate

  • Accepts Ø1" (Ø25 mm) Optics up to 0.14" (3.6 mm) Thick
  • SM1 Internal Thread Directly Compatible With Our SM1-Series Components
  • Two Retaining Rings (SM1RR) Included

The QRC1A cage mount is equipped with a spring-loaded dovetail clamp that secures or releases the cage mount to two of the four ER rods in the cage structure. The cage plate has internal SM1 threading that allows for components up to 0.2" (5 mm) thick to be secured with the included SM1RR retaining ring. In addition, components up to 5/16" (7.9 mm) thick (not including length of threaded stub, OD = 1.2" (30 mm)) with external SM1 threading can be attached without sacrificing the ability to remove the cage plate from a closed cage system. For instance, all of the SM1 threaded ND filters can be used with this cage plate.

 

Removable 30 mm Cage Plate

  • 30 mm Cage Systems Compatible
  • Easy Placement and Removal of a Ø1" Optic Within an Assembled 30 mm Cage System
  • SM1 (1.035"-40) Tapped Hole Directly Accepts Optics Up to 0.20" (5.1 mm) Thick
  • Two Retaining Rings (SM1RR) Included

The STK01 cage plate allows Ø1" optics to be inserted or removed from a closed 30 mm cage structure. The cage plate uses two bands that are locked in place with the internal SM1 (1.035"-40) threading Ø1" optics up to 0.20" (5mm) thick to be secured in the cage plate using the included SM1RR retaining ring. In addition, components up to 5/16" (7.9 mm) thick (not including length of threaded stub, OD = 1.2" (30 mm)) with external SM1 threading can be attached without sacrificing the ability to remove the cage plate from a closed cage system. For instance, all of the SM1 threaded ND filters can be used with this cage plate.

 

30 mm Cage Plate with Quick-Release Magnetic Plate

  • 30 mm Cage Compatible Back Plate
  • Magnetically Coupled Mounting Carriage
  • Accepts Ø1" (25.4 mm) Optics up to 0.20" (5.1 mm) Thick
  • Angular Repeatability Better than 1 µrad
  • Lateral Repeatability Better than 10 µm in X, Y, and Z
  • Back Plate and Mounting Carriage Have Internal SM1 Threading
  • One Retaining Ring (SM1RR) Included

The CP90F consists of a back plate compatible with the 30 mm cage system and a mounting carriage (front plate) that is magnetically coupled with pairs of rare earth magnets to the back plate. For stability, precision, and repeatability, the mounting carriage contacts the back plate at three points. Each point of contact is a ball bearing on the mounting carriage resting in the groove formed by two parallel steel pins. Since the axes defined by the three sets of pins share a common point of intersection, the system is properly constrained (kinematic). The mounting carriage can be easily inserted or removed from the fully assembled cage system by separating it from the back plate, rotating it sideways, and then extracting it from the cage.

The internal SM1 threading allows components up to 0.20" (5.1 mm) thick to be secured in the mounting carriage with the included SM1RR retaining ring. Components with external SM1 threading, like the SM1A7 alignment guide, can be threaded onto the mounting carriage. However, components mounted in this way (OD = 1.2" (30 mm)) cannot extend more than 3/16" (4.7 mm) beyond the face of the mounting carriage without sacrificing the ability to remove the mounting carriage and component from a closed cage system. The lateral repeatability specification (10 µm) indicates that the X, Y, and Z position of the mount will not vary by more than
10 µm after being removed and replaced, while the 1 µrad angular repeatability refers to the rotation of the optic not changing by more than 1 µrad.

Both the CP90F and CP90F-B cage rod through holes have side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key.

 

30 mm to 60 mm Cage Plate Adapter

  • Couples 30 mm and 60 mm Cage Systems
  • Centered SM1 (1.035"-40) Tapped Hole Directly Accepts Ø1" Optics up to 0.35" (9 mm) Thick
  • 8-32 (M4) Tapped Hole for Post Mounting

The LCP02(/M) cage plate provides a convenient means for coupling 30 mm and 60 mm cage assemblies via our Ø6 mm ER Cage Rods. The centered SM1 (1.035"-40) tapped hole directly accepts optics up to 0.35" (9 mm) thick (SM1RR retaining rings sold separately). Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key. The LCP02(/M) also has an 8-32 (M4) tapped hole for post-mounting.

Additionally, two of these cage plates can be used to straddle a 30 mm cage subassembly in such a way that the entire assembly [LCP02(/M), 30 mm subsystem, and LCP02(/M)] can slide along the 60 mm cage rods as a single optomechanical unit. A 16 mm cage assembly can also be easily integrated by utilizing the SP05 cage plate adapter (sold above).

 

30 mm Cubes

  • Two Models for 30 mm Cage Systems
  • Two Sides with Ø1.75" (44.5 mm) Through Holes
  • C4W: Four Sides with Four 4-40 Tapped Holes Around an SM1-Threaded Hole
  • C6W: Two Sides with Four 4-40 Tapped Holes and Two Sides with Ø6 mm Clearance Through Holes Around an SM1-Threaded Hole
  • Compatible with Ø6 mm ER Series Cage Rods
  • Compatible with all Accessories Sold on this Page

The C4W offers four planar cube faces with 4-40 tapped holes for mounting cage system rods centered on an SM1 (1.035"-40) threaded hole. The "top" and "bottom" faces of the cube are machined with Ø1.75" (44.5 mm) holes and tapped holes designed for mounting our Cage Cube Plates (featured below).

The C6W offers the same machined face options as the C4W with the exception of two opposing faces machined with Ø6 mm through-holes rather than 4-40 tapped holes. This allows cage rods to pass through the cube, rather than be fastened to it. This unique feature allows the cube to be translated along the cage rods, and then locked in place with the included setscrews.

These cage cubes are compatible with a range of 30 mm Cage Components, including port hole covers and cage cube platforms.
