Software
Kinesis Version 1.14.53
The Kinesis Software Package, which includes a GUI for control of Thorlabs' Kinesis system controllers.
Also Available:
- Communications Protocol
Figure 58A Kinesis GUI Screen
Thorlabs offers the Kinesis software package to drive our wide range of motion controllers. The software can be used to control devices in the Kinesis family, which covers a wide variety of motion controllers ranging from small, low-powered, single-channel drivers (such as the K-Cubes®) to high-power, multi-channel benchtop units and modular 19" rack nanopositioning systems (the MMR60x Rack System).
The Kinesis Software features .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 and APIs are included with each install. A Central Sequence Manager supports integration and synchronization of all Thorlabs motion control hardware.
By providing this common software platform, Thorlabs has ensured that users can mix and match any of our motion control devices in a single application, while only having to learn a single set of software tools. In this way, it is perfectly feasible to combine any of the controllers from single-axis to multi-axis systems and control all from a single, PC-based unified software interface.
The software package allows 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 2024-07-24 06:38:49.613) Dear Thorlabs,
I am currently fiddling with integrating a CT1A/M in a setup which has 60 mm cage systems and 30mm ones nested. The main hurdle is the side mounted actuator (I put in a Z925B motor which was available), which collides with the 60mm cage. Maybe a version of the CT1A(/M) with an end-mounted actuator port, like it is on the CT1P, would be a good addition to the product line.
Best

(posted 2024-07-25 01:15:42.0) Thank you for contacting Thorlabs. While you would not be able to simply drop this product into a pre-existing 60 mm cage system, you can include in such a system by either only having three of the four cage rods utilized where this part is mounted, or using an adapter such as our LCP6X and not having the cage rods go all the way through the holes on the 60 mm cage plate corners, essentially having two separate 60 mm cage systems on either side of the CT1A(/M). I have reached out to you directly to discuss this further. Aaron Mueninghoff
(posted 2024-03-09 09:08:34.96) The locking screws included with this are too short. They have to be screwed almost completely out of the threading to actually lock the cage rods. If they were just 1.5 times longer, it would be much better. jdelia
(posted 2024-03-11 02:04:31.0) Thank you for reaching out. We will look into the possibility of incorporating this suggestion in the future with regards to our part CT1A. user
(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?

(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
- Integrated Piezo Actuator and Driver
- 160 µm Closed Loop Piezo Travel Range
- 0.5 µm Resolution (Closed Loop)
- M6 x 0.25 Screw for Coarse Adjustment
- 12 mm Travel
- 250 µm Adjustment per Revolution
- Precision Crossed-Roller Bearings
- Control Piezo with Knob, Kinesis® GUI, or External Voltage
- Adapter Plate for Secure Mounting (Sold Separately)
- Accessories Available for Mounting Optics (Sold Separately)
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.
