Cage System Overview
The Cage Assembly System provides a convenient way to construct large optomechanical systems with an established line of precision-machined building blocks designed for high flexibility and accurate alignment.
16 mm, 30 mm, and 60 mm Cage System Standards
Thorlabs offers three standards defined by the center-to-center spacing of the cage assembly rods (see image below). The 16 mm cage, 30 mm cage, and 60 mm cage standards are designed to accomodate Ø1/2", Ø1", and Ø2" optics, respectively. Specialized cage plates that allow smaller optics to be directly inserted into our larger cage systems are also available.
Standard Threads
The flexibility of our Cage Assembly System stems from well-defined mounting and thread standards designed to directly interface with a wide range of specialized products. The three most prevalent thread standards are our SM05 Series (0.535"-40 thread), SM1 Series (1.035"-40 thread), and SM2 Series (2.035"-40 thread), all of which were defined to house the industry's most common optic sizes. Essential building blocks, such as our popular lens tubes, directly interface to these standards.
An example of the standard cage plate measurements determining cage system compatibility.
| Standard Cage System Measurements | |||
|---|---|---|---|
| Cage System | 16 mm | 30 mm | 60 mm |
| Thread Series | SM05 | SM1 | SM2 |
| Rod to Rod Spacing | 16 mm (0.63") | 30 mm (1.18") | 60 mm (2.36") |
| Total Length | 25 mm (0.98") | 41 mm (1.60") | 71.1 mm (2.8") |
| Cage Components | ||
|---|---|---|
| Cage Rods | 16 mm | These rods are used to connect cage plates, optic mounts, and other components in the cage system. The SR Series Cage Rods are compatible with our 16 mm cage systems, while the 30 mm and 60 mm cage systems use ER Series Cage Rods. |
| 30 mm | ||
| 60 mm | ||
| Cage Plates | 16 mm | These serve as the basic building blocks for a cage system. They may have SM-threaded central bores, smooth bores sized for industry standard optics or to accommodate the outer profile of our SM Series Lens Tubes, or specialized bores for other components such as our FiberPorts. |
| 30 mm | ||
| 60 mm | ||
| Optic Mounts | 16 mm | Thorlabs offers fixed, kinematic, rotation, and translation mounts specifically designed for our Cage Systems. |
| 30 mm | ||
| 60 mm | ||
| Cage Cubes | 16 mm | These cubes are useful for housing larger optical components, such as prisms or mirrors, or optics that need to sit at an angle to the beam path, such as beamsplitters. Our cage cubes are available empty or with pre-mounted optics. |
| 30 mm | ||
| 60 mm | ||
| Post and Breadboard Mounts and Adapters | Mounting options for cage systems can be found on our Cage System Construction pages. Cage Systems can be mounted either parallel or perpendicular to the table surface. | |
| Size Adapters | Cage System Size Adapters can be used to integrate components from different cage system and threading standards. | |
| Specialized Components | Thorlabs also produces specialized cage components, such as Filter Wheels, a HeNe Laser Mount, and a FiberPort Cage Plate Adapter, allowing a wide range of our products to be integrated into cage-mounted optical systems.

(posted 2019-09-23 01:41:48.393) there 're some holds in Solidwork file are clear holes and in pdf file, are thread holes. YLohia
(posted 2019-09-24 10:06:45.0) Hello, we only use cosmetic threads on the Solidworks files to save on service space and easy mating of different components. schneider
(posted 2017-09-28 12:29:33.84) I use CM1-BP108 beamsplitters. I also use the CM1-CC cage cube connector. What I miss are additional 0.09in location holes perpendicular to the existing ones. This would give the possibility to rotate the cubes against each other in 90° steps. nbayconich
(posted 2017-10-18 04:15:58.0) Thank you for your feedback. We can provide a quote for this as a custom option. I'll contact you directly with more information. petr.bruza
(posted 2014-05-11 18:25:35.863) Please, was the design of the CM1-4ER cube improved since last feedback? The problem is either that the walls of the cube are too thin, or that the base, when screwed in place, prevents to tighten the SM1 tubes. I damaged two mirrors due to this flaw by tightening SM1 tubes, that caused bending of the base. I need to have the possibility to securely tighten the SM1 tubes. Thank you cdaly
(posted 2014-05-12 10:56:34.0) Response from Chris at Thorlabs: This was modified shortly after the last feedback comment. The current cube design will accommodate the full engagement of the lens tube thread. tcohen
(posted 2012-07-10 11:43:00.0) Response from Tim at Thorlabs: Thank you for your feedback! We are taking a look into this problem and any redesigns that would improve this product. Thank you very much for bringing this to our attention. ppxap3
(posted 2012-07-05 10:36:06.0) I think there is a flaw on the design of this part. The cube base get is the way if one tries to screw in an SM1 tube on the sides. |

CM1-CC Connecting Multiple 1.5" Wide Cage Cubes
- Connect Two 1.5" Wide Cage Cubes Side by Side
- Connect a 1.5" Wide Cage Cube to a 2" Wide Cage Cube
- Compatible with CM1 or CCM1 Series Cage Cubes
The CM1-CC cage cube connector allows two or more CM1 or CCM1 style cubes to be connected as shown in the image to the right. The CM1 and CCM1 series of cage cubes, which are all compatible with this connector, include empty cubes, empty dichroic cubes, mounted beamsplitters, mounted penta prisms, and mounted turning mirrors. The CM1-CC cage cube connector includes four 4-40 button-head screws, two 4-40 flat-head screws, four washers, and a 1/16" hex key.
Two cage cube-mounted turning mirrors cannot be connected using the CM1-CC due to a lack of Ø6 mm cage rod holes on two sides of the cube.
We also offer the C4W-CC to connect two 2" wide 30 mm cage cubes. Both C4W-CC and CM1-CC cage cube connectors can be used to connect one 1.5" wide 30 mm cage cube, such as our CCM1-4ER(/M), with a 2" wide 30 mm cage cube.
Alignment Pins
Please note that because dowel alignment pins are used, the connector requires drilled holes on the cube face between the SM1-threaded (1.035"-40) ports. If you have an older cube and would like it updated to have alignment holes 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 cubes that do not have these alignment holes.
