The Thorlabs CXYZ05A(/M) Translation Mount offers X-, Y-, and Z-Axis travel and holds Ø1/2" (12.7 mm) optics, up to 0.31" (8.0 mm) thick, against the back lip of the optic cell using the provided SM05RR retaining ring. XY functionality allows travel perpendicular to the optical axis, while the Z-axis functionality allows for compensation of focusing errors in applications such as fiber alignment or lens mounting. The optic cell has been designed to offer pure X, Y, and Z translation.

The CXYZ05A(/M) mount can easily be adapted to a 16 mm Cage System using an SP15(/M) 30 mm to 16 mm Cage Adapter Plate.

The optic cell is internally SM05 (0.535"-40) threaded and is translated along the Z-axis by rotating the zoom adjustment dial on the back of the mount. The optic cell does not rotate during translation. An engraving is included on the knurled dial, indicating the direction that it must be turned for translating the optic cell forward and backwards. Laser-engraved tick marks spaced 0.25 mm apart are included on the optic cell for indicating the Z-axis position. The position can be locked using an SM15RR Retaining Ring (sold separately); see the image to the bottom right for more details.

The Z-Axis position can be locked by threading an SM15RR retaining ring (sold separately) onto the internal threads of the rear knurled knob. This can be done using the SPW801 Spanner Wrench.

X and Y translation of the carriage is accomplished using the two 3/16"-100 fine adjusters, which can be locked using the provided nylon-tipped setscrew and 0.035" hex key. Horizontal and vertical witness lines provide a reference for the XY alignment.

The mount has four through holes for use with our Ø6 mm ER cage rods, making it compatible with our 30 mm Cage Systems; it also has side-located M4 x 0.7 setscrews, which use a 5/64" (2.0 mm) hex key, to lock the cage rods in place. The mount can easily be adapted to 16 mm Cage Systems by using an SP15(/M) Cage Adapter Plate, as shown in the image to the left. Two 8-32 (M4) tapped holes are also provided on opposite sides of the XY adjusters for post mounting in right- or left-handed orientations.

Thorlabs also offers a 60 mm cage compatible XYZ translation mount for Ø1" optics, available here.

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 accommodate 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 (2.80")
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
Replacement Setscrews Replacement setscrews are offered for our 16 mm (SS4B013, SS4B025, and SS4B038) and 30 mm (SS4MS5 and SS4MS4) cage systems products.
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.

Need a 30mm system for sm1!!!

Hello, thank you for your feedback. We looked into this during the initial design stages of the CXYZ05 but, unfortunately, the physical constraints inside the unit made this impossible.
