Features

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.

Thorlabs introduced the SM Series Threading standards to ensure compatibility over a broad range of product lines. SM-Threaded components offer a simple and efficient solution for building optomechanical structures. The SM-Threaded products available, which include lens tubes and cage system components, fixed and kinematic mounts, irises and diaphragms, and mounted optics, provide flexibility when constructing complex optical systems.

SM1-Threaded Dual Flexure Cage Plate


Click to Enlarge
The CP02F(/M) Cage Plate offers a 1/4"-20 (M6) tap for mounting on our Ø1" Posts.

Click to Enlarge

Cage rod arms can flex to compensate for cage rod misalignment due to tolerance stacking.
  • Self-Aligning Cage Rod Arms Eliminate Cage Plate Binding
  • Tapped with Our Standard SM1 Thread (1.035"-40)
  • Directly Mounts Optical Components Within a 30 mm Cage System Assembly
  • Post Mountable via 8-32 (M4) and 1/4"-20 (M6) Tapped Holes

The CP02F(/M) Flexure Cage Plate features a flexure arm design for locking onto 30 mm cage rods. This design compensates for the tolerance stacking effects common in cage systems, ensuring that the cage plate never binds or sticks within a constructed cage segment. The cage plate's orthogonal flexure arms remain rigid when handled, but will flex slightly to provide compensation for rod misalignment when installed within a constructed cage segment. This unique feature is illustrated in the diagram to the right. In contrast with the standard setscrew retention method of the CP02 Cage Plate, each CP02F arm clamps onto cage rods using a separate flexure clamp that increases holding force and cage plate rigidity.

Like our our CP02(/M) cage plate, it 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 CP02F(/M) can also directly accept a Ø1" optic up to 0.19" (4.8 mm) thick. Two SM1RR retaining rings are included. The cap screw on each flexure cage rod through hole can be tightened using a 5/64" (2.0 mm) hex key or Thorlabs' HKTS-5/64 Hex Key Thumbscrews.

For additional convenience, 8-32 (M4) and 1/4"-20 (M6) tapped holes are provided on opposite sides of the cage plate for post mounting applications. For Ø1" optics thicker than 0.125" (3.2 mm), we offer the CP06F(/M) Cage Plate with a Ø1" Double Bore.

  • Ø1.2" Bore Supports Outside Diameter of SM1 Lens Tubes and C-Mount Extension 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 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 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 (Item # HK050).

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.

Rotating Cage Plate for 30 mm Cage Systems

CPR1 Application
Click to Enlarge

Rotating 30 mm Cage System
  • Rotates an Entire 30 mm Cage System Subassembly Around a Fixed SM1-Threaded Bore
  • Post Mountable via 8-32 (M4) Tapped Hole
  • Rotation Locked with Flexure Mechanism

Thorlabs' CPR1 30 mm Rotating Cage Segment Plate allows an entire 30 mm cage subsystem to be rotated about the optical axis. The CPR1 consists of two plates: one attaches to a fixed cage segment, while the other rotates all attached cage elements. To rotate a cage segment between two fixed cage segments, two CRP1 plates must be used as shown in the image to the right. The rotating cage segment is ideal for rotating multiple optical elements where the rotation of each element must be the same (e.g., using two cylindrical lenses to change the spatial profile of a laser diode or for multi-element polarization applications).

The rotating cage segment plate features a 1" deep, SM1-threaded (1.035"-40) central bore through the part that remains fixed as the plate is rotated. Two SM1RR retaining rings are provided for direct mounting of optics.

Each side of the cage plate has four blind holes for attaching cage rods, and thus, the cage rods must terminate at this cage plate. Each rod is held in place by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key (Item # HK050). An engraved scale with 2° graduations allows for reliable manual positioning. After the rotation is adjusted, a flexure locking mechanism, which is engaged with a 3/32" hex key, secures the rotation. The fixed side of the cage plate is equipped with an 8-32 (M4) tapped hole for mounting with our Ø1/2" posts.

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 Mounting to Ø1/2" Posts

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 Ø1/2" post mounting. The surface with the 8-32 (M4) tap is not wide enough to support Ø1" posts.

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 Cage Plate with Quick-Release Magnetic Plate

application image of the quick release cage mount
  • 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.

Cylindrical Lens Mount for 30 mm Cage Systems

This animation depicts various mounting options of the CYCP Cylindrical Lens Mount.

  • Rectangular Optic Mount for 30 mm Cage Systems
  • Two Manually Positioned Arms Hold Optics up to 0.66" (16.8 mm) Tall Within the Cage System
  • Internal SM1 (1.035"-40) Threads Compatible with Ø1" Lens Tubes
  • Graduations at 1 mm Intervals Help with Centration and Repeatability

Thorlabs' Cylindrical Lens Mount for 30 mm Cage Systems is designed to orient a cylindrical lens or another rectangular optic horizontally or vertically within a 30 mm cage system. The lens is effectively clamped between the two sliding arms, each of which is lined with a 1.51" (38.3 mm) long rubber pad and has a lip for resting the plano side of the lens against. The manually positioned arms can hold optics from 0.16" to 0.66" tall (4.0 mm to 16.8 mm) before the arms begin to obscure the through holes for the cage system.

Each arm is secured to the side-mounted 2" long cage rods (Item # ER2) using two 4-40 setscrews that accept a 0.05" (1.3 mm) hex key. The cage plate is tightened to these cage rods by two additional 4-40 setscrews. The cage plate and arms can be moved and locked independently. Hence, by loosening the cage plate while keeping the arms tightened, the user may translate a lens parallel to the cage rods (i.e., in a transverse direction) without disturbing the rest of the cage system. The arms can also be relocated from the front of the cage plate to the back of the cage plate.

  • 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.

CM1-4ER with Penta Prism (Optic Sold Separately)

These 1.5" wide cage cubes directly accept a 1" square optic, such as a beamsplitter cube or right-angle prism, with adapters available here for mounting a 5 mm (0.20"), 10 mm (0.39"), 12.7 mm (0.50"), or 20 mm (0.79") beamsplitter cube. The base of the cube has an 8-32 (M4) tap to attach to Ø1/2" Posts. The M4 tapped hole on the CCM1-4ER/M is located on the base of the cube providing increased mounting stability. Therefore, the optical beam height of the CM1-4ER and CCM1-4ER/M is 0.94" and 0.75", respectively. Shown to the far right is a 12.7 mm (0.50") beamsplitter cube being mounted in the CM1-4ER using the BS127CAM Beamsplitter Cube Adapter. Two cage cubes can be connected using ER rods and ERSCA Cage Rod Adapters.

The optic is clamped within the cube by tightening three hex screws of a tension plate (see image above), allowing the user to replace the optic with any other compatible optic when necessary. The optic must sit flush against the three corners of the cube base. Do not over tighten the tension plate, this can damage the optic. The image above shows a penta prism mounted in a CM1-4ER with the outer housing removed.

C4W-CC Connecting Two 2" Wide Cage Cubes
  • Connect Two 2" Wide Cage Cubes Side by Side
  • Connect a 2" Wide Cage Cube to a 1.5" Wide Cage Cube
  • Compatible with C4W and C6W Cage Cubes

The C4W-CC allows our 2" wide 30 mm cage cubes to be connected together as shown in the image to the right. Our C4W and C6W cubes are both compatible with this connector. This connector can also be used to connect one 2" wide 30 mm cage cube, such as our C4W or C6W, with a 1.5" wide 30 mm cage cube.

We also offer the CM1-CC to connect two 1.5" wide cage cubes.

Alignment Pins
Please note that this connector requires drilled holes on the cube face next to the SM1-threaded ports, as the cube connector has alignment pins. If you have an older cube and would like it updated for free, please contact Technical Support. Alternatively, the alignment pins are press-fit inside their mounting holes and can be pressed out for use with un-drilled cubes.
