SM05-Compatible Translation Mounts
16 mm Cage
30 mm Cage XY
16 mm Cage
XYZ Translation Mount
Precision XY Translation
The products available below all contain internal SM05 (0.535"-40) threads, which are ideal for constructing complex, rigid optomechanical systems. SM05-threaded products available include: lens tubes and cage system components, fixed and kinematic mounts, and irises and diaphragms.
SM05-threaded (0.535"-40) components are designed to mount or integrate Ø1/2" (Ø12.7 mm) optics into systems. These SM05-threaded mounts translate the mounted optic perpendicular to the optical axis in both the X and Y axes. The CXYZ05 also offers 3 mm of Z-axis adjustment along the optical axis.
This page contains our SM05-compatible optic translation mounts; for a full selection of available optic translation mounts, please see here.
Usage of the Light-Tight SCP05T Translation Mount

SCP05 and SCP05T
Thorlabs' SCP05 and SCP05T XY translating lens mounts provide ±1.0 mm (±0.04") of travel perpendicular to the optical axis of a 16 mm cage system. The adjusters feature 100 threads per inch and provide 250 μm of translation per revolution. The adjusters may be actuated by hand or using a 5/64" (2.0 mm) hex key or balldriver and the setscrews for mounting cage rods offer a 0.05" (1.3 mm) hex.
The SCP05 and SCP05T mounts both contain internal SM05 threads suitable for mounting Ø1/2" (12.7 mm) optics up to 0.23" (5.8 mm) thick using the included SM05RR retaining ring. The optic is held in place by the retaining ring and the retaining lip built into the SM05-threaded carriage. Additionally, the SCP05T mount contains internal SM05 threads on the front and rear faces of the housing (as illustrated in the diagram above), allowing light-tight connections to our Ø1/2" lens tubes. (The SCP05 is only threaded on the rear face.)
To remove/install the SM05RR retaining ring or an optic, the adapter retaining ring on the front of the mount must first be removed using an SPW801 Spanner Wrench. For reference, please see the animation above and to the right.
This mount utilizes M3 x 0.25 fine adjustment screws to provide ±1 mm of travel perpendicular to the optical axis. The adjustment screws provide 250 µm/rev, and there is a 5/64" hex socket in the back end of each screw. A hex key may be used to achieve small incremental movements. The movable carriage is internally SM05 (0.535"-40)-threaded and directly accepts Ø1/2" optics held in place by an SM05RR Retaining Ring (included). This also makes the mount compatible with any internally SM05-threaded component.
Please note that the moving SM05-threaded world may be manually rotated and may also rotate during translation.
The CT102 has an internal SM05 (0.535"-40) threading for mounting Ø1/2" components up to 0.39" (9.9 mm) thick or externally SM05-threaded components. The CT102 allows for ±1 mm of travel in the X and Y direction using M3 x 0.25 fine adjusters. The mount is directly compatible with the CT1 30 mm cage Z-axis translation stage and the MS1(/M) Translation Stage when it is used with the MS103(/M) adapter plate. One SM05RR retaining ring, which secures a component by sandwiching it between the ring and the back lip on the mount. Two 4-40 and two M3 cap screws for securing the mount are included with each unit.
The CP1XY offers ±0.25 mm of XY travel manipulated by M2.5 x 0.20 fine pitch adjusters. The stainless steel flexure design provides excellent long-term stability and is ideal for fiber coupling applications or experiments that use spatial filters or pinholes, which require fine positioning. The 0.35" (8.89 mm) long center bore is tapped through with an SM05 (0.535"-40) thread to allow the integration of our extensive SM05-threaded family of products. The CP1XY is vacuum compatible to 10-5 Torr. We recommend using two POLARIS-SM05RR vacuum-compatible, stainless steel retaining rings (sold separately) to secure an optic in the bore while under vacuum conditions. Alternatively, for non-vacuum applications, we offer SM05RR anodized aluminum retaining rings.
Thorlabs' SSP05 16 mm Slip Plate Positioner is designed to provide coarse XY positioning of optical components within our cage assembly system. The component that provides position adjustment is the movable carriage, which moves along the surface of the other plate for small XY adjustment. The movable carriage provides manual adjustment only and is best utilized in conjunction with an alignment laser to monitor centricity.
Adjustment is achieved by first loosening the two 2-56 button-head adjustment screws with a 0.05" (1.3 mm) hex key or balldriver, manually adjusting the movable carriage in the desired position, and then tightening the screws to lock the carriage in place. The movable carriage is internally SM05 threaded and compatible with our Ø1/2" lens tubes, which can be used to hold Ø1/2" optics. Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" (1.3 mm) hex key or balldriver.

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.

Translation of the Z-Axis Carrier Achieved by Rotating the Engraved Adjustment Dial
The Thorlabs CXYZ05(/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 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 right for more details.
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. Each cage rod mounting hole has a side-located 4-40 locking setscrew, which uses a 0.05" hex key. The mount can easily be adapted to 16 mm Cage Systems by using the SP05 Cage System Size Adapter, 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.
