XY Translation Mounts for 30 mm Cage Systems
Stainless Steel Construction
SM05 (0.535"-40) Compatible
0.5 mm Range in X and Y Directions
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. The center of the plate is tapped through with an SM05 (0.535"-40) thread to allow the integration of our extensive SM05 threaded family of products. The stainless steel adjustment plate is vacuum compatible to 10-5 Torr.
±1 mm Travel in X and Y
The CXY1 XY Translator provides ±1 mm of travel perpendicular to the optical axis of a 30 mm cage system. The movable carriage is internally SM1 (1.035"-40) threaded and directly accepts Ø1" optics up to 0.39" (10.0 mm) thick when secured using the included SM1RR retaining ring. The fixed back side is also threaded to allow SM1 lens tubes to be attached. The center carriage has been designed to offer pure X and Y translation. The translation is actuated by two 3/16"-100 lockable adjusters. The mount features vertical and horizontal tick marks to help maintain alignment of the mounting carriage.
The ST1XY translation stage utilizes hardened tool steel components on all moving parts to ensure long-term, drift-free operation. The ST1XY is designed to connect with our extensive line of Ø1" SM1 Lens Tubes as well as our 30 mm cage assemblies to offer great flexibility when building optical systems. Three 8-32 (M4) tapped holes are provided on the bottom surface to allow direct mounting on our Ø1/2" Posts.
The ST1CP is a bolt-on adapter designed specifically for use with the ST1XY-series of XY translators. Like our ERSCA adapter, this plate can be used to connect two internally threaded cage components with ER rods. First thread the four included 4-40 screws through the ST1CP through hole and into the internally bored side of the ER rod (as shown in the figure to the left). Then, remove the back plate on an ST1XY stage and secure this adapter plate in its place using the four outer 2-56 counterbored through-holes. Once attached, this adapter plate keeps the cage and any SM1-threaded component attached to the adapter plate stationary, while enabling an optic inside the ST1XY stage to move relative to these fixed components.
Alternatively, this adapter can also be attached to the front side (i.e., the side without the removable mount) of an ST1XY stage using the included 4-40 screws. In this case, the front side of the ST1XY stage will no longer be cage compatible (although the back side still is). However, the advantage of this configuration is that two SM1-compatible components can be attached to the ST1XY stage (one on each side) and an optic inside the stage can be moved relative to these fixed components.
The two locking screws can also be threaded through counterbores in the back plate of the SPT1T (shown here) or SPT1.

The SPT1(/M) and SPT1T(/M) Slip Plate Positioners are designed to provide coarse XY positioning of optical components within our 30 mm Cage Assembly System. This design provides for manual adjustment only and is best utilized in conjunction with an alignment laser to monitor centricity. The front plate can be locked into position against the fixed plate via two locking screws, which can be threaded from either the front or back side of the mount.
The SPT1(/M) accomodates Ø1" optics up to 0.08" (2.03 mm) thick, while the thicker front plate on the SPT1T(/M) can hold Ø1" optics up to 0.34" (8.6 mm) thick. Unmounted optics can be secured with SM1RR Retaining Rings, two of which are included with the SPT1T(/M). The center-located SM1 (1.035"-40) tapped through hole also directly accepts externally SM1-threaded components.

The CPA1 and CPA2 Alignment Plates are convenient tools for aligning cage-based optical systems. These drop-in plates feature a small through hole at the exact center of the 30 mm cage assembly that is used for aligning visible beams. For easy alignment, the through hole is surrounded by engraved rings, which indicate Ø4 mm, Ø7 mm, Ø10 mm, and Ø12 mm. The CPA1 provides a Ø1 mm through hole, while the CPA2 provides a Ø5 mm through hole.
The VRC4CPT Alignment Plate is specifically designed to align IR beams in a cage-based optical assembly. The front is identical to the CPA1 (shown to the left), and the back (shown to the right) includes a non-rotating IR-sensitive fluorescing alignment disk made of the same material used in our VRC4 Viewing Card. This disk has a centered Ø2 mm through hole, while the plate has a Ø1 mm centered through hole. See the table below for more information.
