Adapter Plate for Mounting CT1P(/M) Stage

The CT1P(/M) 12 mm Manual Travel Translation Stage with Integrated Piezo Actuator is designed to be used in 30 mm cage systems that require translating a component along the optical axis of the cage system. This stage incorporates precision crossed-roller bearings to ensure smooth, high-resolution motion. The stage can be roughly positioned using the "COARSE ADJUST" knob, which provides 250 µm of travel per revolution and can be locked using the included 1.5 mm hex key. The piezo actuator integrated in this stage must have power supplied using the included micro USB to USB A cable. The USB cable should be connected to a PC directly or via a powered USB hub. Turning the "FINE ADJUST" knob provides an adjustment of 0.5 µm resolution through 160 µm of travel in closed-loop operation. The piezo can be toggled between open- and closed-loop modes via the "OPEN/CLOSE" button on the front. Holding this button homes the piezo, putting it in the middle of its travel range. The coarse and fine adjustment knobs can be operated using a 2 mm (5/64") balldriver (not included); they should not be operated simultaneously.

The piezo actuator can also be controlled remotely using the Kinesis^® software or by applying an external voltage to the EXT IN port (MMCX, 0 to 10 VDC). The default parameters of the CT1P(/M) stage can be altered using the Kinesis software, and settings such as jog step, PID parameters, and Trigger I/O can be persisted to the hardware as well. The two bidirectional I/O ports (MMCX) are disabled on default, but can be enabled using Kinesis and allow the user to use them either as input or output. Input mode uses TTL logic, while output mode provides a push-pull drive of 5 V, with a maximum current limit of 8 mA. There is also a MONITOR output port (MMCX, 0 to 10 V) which provides a digital representation of the piezo voltage. To download the software, see the Kinesis Software tab.

The moving world of the stage features six 4-40 (M3) holes and a center 4 mm keyway, allowing the accessories sold below to be easily mounted to the CT1P(/M) and exchanged depending on the application. Two 30 mm cage rods can be attached to the fixed world of the stage by positioning them in the slots on each side. The rods can then be secured by tightening the four included cone-ended M4 setscrews using a 2 mm (5/64") hex key or balldriver. If the stage is only mounted to the cage system, the cage rods should be supported near the stage using cage system mounts.

The CT1P(/M) stage features two 8-32 (M4) holes on the bottom which can be used to mount the stage in a variety of configurations. The CT1PA adapter plate, sold separately, offers a quick, low-profile solution to securing the stage, as shown in the image above to the right. Alternatively, the stage can be mounted using our Ø1/2" optical post assemblies or Ø1" optical post assemblies, although care should be taken to accomodate the non-standard hole spacing of 3.11" (79.0 mm). This can be achieved using pedestal posts with clamping forks, pedestal post holders with clamping forks, or a variety of post holder bases.

CXY1A XY Translator Coupled to a CT1A Z-Axis Translation Mount Using an SM1S15 Lens Tube

• Includes 1/2" (13 mm) Travel Micrometer with 0.001" (10 µm) per Graduation 
• Comes with CT101 Ø1" Optic Mount for Optics up to 0.27" (6.9 mm) Thick
• Precision Linear Ball Bearings
• Lockable Design

The CT1A(/M) Manual Translation Stage is designed to be used in 30 mm cage systems that require translation along the optical axis of the cage. This translation stage includes a CT101 Ø1" optic mount, which is also available separately below. Precision linear ball bearings are used to ensure smooth, high-resolution motion. The CT1A(/M) features a graduated micrometer that provides 1/2" (13 mm) of linear translation with 0.001" (10 µm) graduations. A 5/64" (2 mm) hex on the micrometer allows for actuation in space-constrained environments. The smallest incremental movement of the carriage is approximately 1 µm.

The modular design allows the accessories sold below to be mounted to the movable carriage of the CT1A(/M) translation stage. The included CT101 Ø1" Optic Mount has internal SM1 threading (1.035"-40) for mounting Ø1" optical components up to 0.27" (6.9 mm) thick, or externally SM1-threaded components, such as our SM1 lens tubes. One SM1RR retaining ring, two 4-40 cap screws for securing the mount, a 1/16" and a 5/64" (2 mm) hex key, and two removable dowel pins for alignment are also included with the mount.
