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.

Smart Pack

  • Reduce Weight of Packaging Materials
  • Increase Usage of Recyclable Packing Materials
  • Improve Packing Integrity
  • Decrease Shipping Costs

Thorlabs' Smart Pack Initiative is aimed at waste minimization while still maintaining adequate protection for our products. By eliminating any unnecessary packaging, implementing packaging design changes, and utilizing eco-friendly packaging materials for our customers when possible, this initiative seeks to improve the environmental impact of our product packaging. Products listed above are now shipped in re-engineered packaging that minimizes the weight and the use of non-recyclable materials.b As we move through our product line, we will indicate re-engineered packages with our Smart Pack logo.

  • Travel-based emissions reduction calculations are estimated based on the total weight reduction of packaging materials used for all of 2013’s product sales, traveling 1,000 miles on an airplane, to provide general understanding of the impact of packaging material reduction. Calculations were made using the EPA’s shipping emissions values for different modes of transport.
  • Some Smart Pack products may show a negative weight reduction percentage as the substitution of greener packaging materials, such as the Greenwrap, at times slightly increases the weight of the product packaging.

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.

Please provide tolerance on the bottom key which is shown as nominal width of 4.0mm. What's the max/min of that width? -Ken Li 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.

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.

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.

Z-Axis Translation Stage: 12 mm Manual Travel & 160 µm Piezo Travel (Closed Loop)

CT1P Stage Mounting to Table Using CT1PA Adapter
Click to Enlarge

CT1P Mounted to Optical Table Using CT1PA Adapter Plate
  • 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.
