Thorlabs' Z-Axis Translation Stages can be fixed to two cage rods in a 30 mm cage system while allowing the translation along the optical axis of a component secured to the moving world of the stage. The CT1P Translation Stage with Integrated Piezo Actuator features 12 mm of manual travel as well as at least 160 µm of piezo travel with 0.5 µm resolution in closed-loop operation. The CT1 Manual Stage features a 1/2" travel micrometer with 0.001" graduations and includes a CT101 optic mount. Both stages are fully compatible with all the optic mounts sold on this page.
We offer optic mounts that are specifically designed for both the CT1 and the CT1P(/M) stages, as well as our 1/4" Translation Stages. These mounts include a fixed optic mount, an X-Y translation mount, a rotation mount, and a blank plate for custom machining. See below for details.

Thorlabs' Kinesis® software can be used to control devices in the Kinesis or APT family, which covers a wide range of devices ranging from small, low-powered, single-channel drivers (such as the K-Cubes and T-Cubes) to high-power, multi-channel, modular 19" rack nanopositioning systems (the APT Rack System).
The Kinesis Software features new .NET controls which can be used by 3rd party developers working in the latest C#, Visual Basic, LabVIEW® or any .NET compatible languages to create custom applications. Low level DLL libraries are included for applications not expected to use the .NET framework. A Central Sequence Manager supports integration and synchronization of all Thorlabs motion control hardware.
The software packages allow two methods of usage: graphical user interface (GUI) utilities for direct interaction with and control of the controllers 'out of the box', and a set of programming interfaces that allow custom-integrated positioning and alignment solutions to be easily programmed in the development language of choice.

(posted 2020-09-16 13:19:20.33) I suggest adding an option for imperial or metric micrometer (as the included micrometer) YLohia
(posted 2020-09-16 03:48:25.0) Thank you for your feedback. We will consider adding this to our stock catalog. Please note that the CT1 can be ordered with a metric micrometer as a special item by emailing techsupport@thorlabs.com. Alternately, you may purchase the 148-801ST (metric micrometer) separately and install it in your CT1. Ken Li
(posted 2020-08-21 22:03:39.79) Please provide tolerance on the bottom key which is shown as nominal width of 4.0mm. What's the max/min of that width?

510-410-4283 YLohia
(posted 2020-08-24 10:27:57.0) Hello Ken, thank you for contacting Thorlabs. The tolerance on the bottom key for the CT102 is 0.157" +0.000"/-0.001". Eric Mueller
(posted 2020-05-28 12:54:57.197) No metric version of the CT1 available (incl. a metric micrometer)?
Cheers,
Eric llamb
(posted 2020-05-28 05:14:27.0) Hi Eric, thank you for your feedback. The imperial micrometer included with the CT1 may be switched out with a metric micrometer (Item # 148-801ST) as needed. We can also provide a custom CT1 with a metric micrometer already included. I have reached out to you directly to discuss this option. akastengren
(posted 2018-08-29 10:46:00.683) Is there a way to put a stepper motor actuator on this product? YLohia
(posted 2018-08-29 11:48:38.0) Hello, thank you for contacting Thorlabs. Yes, it is possible to install a stepper motor actuator (such as the ZST213B) in the CT1 since it has a 3/8" mounting barrel. acable
(posted 2007-12-31 08:28:00.0) The description in the price box for the CT1 reads: 1/2" Cage Translation Stage. Please consider: 1/2" Travel 30mm Cage translator with CT101. |

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.

- Includes 1/2" Travel Micrometer with 0.001" per Graduation
- Comes with CT101 Ø1" Optic Mount for Optics up to 0.35" (8.9 mm) Thick
- Precision Linear Ball Bearings
- Lockable Design
The CT1 Manual Translation Stage is designed to be used in 30 mm cage systems that require translation along the optical axis of the cage. This translator 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 graduated micrometer provides 1/2" (12.7 mm) of linear translation and has 0.001" graduations. The smallest incremental movement of the carriage is approximately 1 µm. The included micrometer (Item # 148-811ST) may be switched out with a metric micrometer (Item # 148-801ST) with 10 µm graduations.
The modular design allows the accessories sold below to be mounted to the movable carriage of the CT1. As shown in the image, the CT1 stage includes the CT101 Ø1" Optic Mount, which has internal SM1 threading (1.035"-40) for mounting Ø1" optical components up to 0.35" thick, or externally SM1-threaded components, such as our SM1 lens tubes. One SM1RR retaining ring, two 4-40 and two M3 cap screws for securing the mount, and two removable dowel pins for alignment are also included with the mount.
