Thorlabs' K10CR2(/M) Rotation Mount, part of our Kinesis® line of motorized optomechanics, stages, and controllers, is a compact stage designed to rotate Ø1" optics or SM1 Lens Tubes within a fixed 30 mm Cage System. The K10CR2(/M) has four, 4-40 tapped holes for the cage rods on each side of the fixed housing. This allows optics, such as wave plates and cylindrical lenses, to be rotated while leaving the other optics in the cage system fixed. The rotating SM1 bore passes through the mount; optics up to 0.67" (17.0 mm) thick may be secured inside the bore using the two included SM1RR retaining rings.
Rotation is driven via a stepper motor equipped with a high ratio worm gear (120:1), providing a unidirectional repeatability of ±60 µrad and a maximum speed of 10 degrees/s. The integrated controller is USB 2.0 and 3.0 compatible; a USB 3.0 cable is provided for compatibility with most computers. The mount is powered by the host PC via the USB cable, minimizing the number of cables needed during operation. In addition, the mount settings can be adjusted using the software, allowing the mount to be used without a PC; in this case power is provided by a USB hub or charger. A jack is provided for TTL input/output signals, which allows for custom timing control and eases synchronization with other components. For more details on these connections, please see the Pin Diagrams tab.
The mounts can be operated with the user friendly Kinesis software, which allow the user to quickly set up complex move sequences. For example, all relevant operating parameters are set automatically by the software for Thorlabs' stage and actuator products. Advanced custom motion control applications and sequences are also possible using the extensive programming environment described in more detail on the Kinesis Software tab. In addition to software control, pushbutton operation is possible, as shown in the image below and to the left. The button function is software-selectable and can be set to either jog the stage a set distance or to move the stage to a set position. Pressing both buttons for two seconds zeros the stage to the "home" position, which is facilitated by a precision home limit switch.

Control buttons located on the edge of the K10CR2 rotation mount; the functions are set via the software and persist if the stage is disconnected from the PC and powered via a USB hub or charger.
The thumbscrew on the side of the housing can be used for manual rotation adjustment. An engraved vernier scale, with 2° graduations on the main dial and 12 arcmin graduations on the vernier scale, also aids in manual alignment. While this manual adjustment can be useful for visual alignment of mounted components, please note that the positioning data will be lost and the mount will need to be homed in order to use software control.
The K10CR2(/M) can be directly mounted to a Ø1/2" Post or Ø1" Post via 8-32 (M4) taps on two perpendicular edges. As shown in the image to the right, two Ø6 mm rods, such as our cage rods, can be used to align multiple rotation mounts along the same axis in post mounting applications (note that these two bores are not located at the correct spacing for attaching cage plates). Six 4-40 (M3) taps on the front surface of the moving dial allow components to be mounted, such as our K6A1(/M) Prism Mounting Adapter.
Alternatively, several mounting adapters are available below. The K10CR1A1 adapter plate facilitates mounting the K10CR2(/M) horizontally, as shown in the image above. Secondly, the K10CR1A2(/M) plate is secured on the rotating dial to provide a variety of taps and a keyway for our flexure stage accessories. Finally, the K10CR1A3 bracket allows the K10CR2(/M) mounts to be inserted within a 60 mm cage system.

Resolution Calculation
For the stepper motor in the K10CR2(/M), there are 200 full steps per revolution of the motor and 2048 microsteps per full step. The output shaft of the motor goes into a 120:1 reduction gearbox.
The angular displacement of the rotation mount per encoder count is given by
200 x 2048 x 120 = 49,152,000.0 microsteps per revolution of the top platform
49,152,000.0/360 = 136533.33 microsteps per degree of movement.
K10CR2(/M) Pin Configurations
The USB 3.0 port is compatible with a USB 2.0 Micro B connector if the Micro B connector is plugged into the shaded region in the photo above. The I/O port requires a user-supplied 3.5 mm 4-way jack plug and cable; the pinout of the mating plug is shown to the right.

Software
Kinesis Version 1.14.50
The Kinesis Software Package, which includes a GUI for control of Thorlabs' Kinesis system controllers.
Also Available:
- Communications Protocol
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.
Legacy Software
Select products are still capable of running the legacy APT™ software package. Information on software compatibility can be found in the product documentation (

Reading a Vernier Scale on a Linear Main Scale
Vernier scales are typically used to add precision to standard, evenly divided scales (such as the scales on Thorlabs' rotation, goniometric, or translation mounts). A vernier scale has found common use in many precision measurement instruments, the most common being calipers and micrometers. The vernier scale uses two scales side-by-side: the main scale and the vernier scale. The direct vernier scale has a slightly smaller spacing between its tick marks owing to the vernier scale having N ticks for every N - 1 ticks on the main scale. Hence, the lines on the main scale will not line up with all the lines on the vernier scale. Only one line from the vernier scale will match well with one line of the main scale, and that is the trick to reading a vernier scale.
Figures 1 through 3 show a linear vernier scale system for three different situations. In each case, the scale on the left is the main scale, while the small scale on the right is the vernier scale. When reading a vernier scale, the main scale is used for the gross number, and the vernier scale gives the precision value. In this manner, a standard ruler or micrometer can become a precision instrument.
The 0 on the vernier scale is the "pointer" (marked by a red arrow in Figures 1 - 5) and will indicate the main scale reading. In Figure 1 we see the pointer is lined up directly with the 75.6 line. Notice that the only other vernier scale tick mark that lines up well with the main scale is 10. Since the pointer lines up with the main scale’s 75.6, the reading from Figure 1 is 75.60 (in whatever units the instrument measures).
That is essentially all there is to reading a vernier scale. It's a very straightforward way of increasing the precision of a measurement instrument. To expound, let’s look at Figure 2. Here we see that the pointer is no longer aligned with a line on the main scale, but instead it is slightly above 75.6 and below 75.7; thus, the gross measurement is 75.6. The first vernier line that coincides with a main scale line is the 5, shown with a blue arrow. The vernier scale gives the final digit of precision; since the 5 is aligned to the main scale, the precision measurement for Figure 2 is 75.65.
Since this vernier scale is 10% smaller than the main scale, moving the vernier scale by 1/10 of the main scale will align the next vernier marking. This asks the obvious question: what if the measurement is within the 1/10 precision of the vernier scale? Figure 3 shows just this. Again, the pointer line is in between 75.6 and 75.7, yielding the gross measurement of 75.6. If we look closely, we see that the vernier scale 7 (marked with a blue arrow) is very closely aligned to the main scale, giving a precision measurement of 75.67. However, the vernier scale 7 is very slightly above the main scale mark, and we can see that the vernier scale 8 (directly above 7) is slightly below its corresponding main scale mark. Hence, the scale on Figure 3 could be read as 75.673 ± 0.002. A reading error of about 0.002 would be appropriate for
this instrument.

Figure 3: The red arrow indicates the pointer, and the blue arrow indicates the vernier line that matches the main scale. This scale reads 75.67 but can be accurately read as
75.673 ± 0.002.
Reading a Vernier Scale on a Rotating Main Scale
The vernier scale may also be used on rotating scales where the main scale and vernier scale do not share units. Figures 4 and 5 show a vernier scale system for two different situations where the main scale is given in degrees and the vernier scale has ticks every 5 arcmin (60 arcmin = 1°). In each case, the scale on the top is the main scale, while the small scale on the bottom is the vernier scale.
In Figure 4 we see the pointer is lined up directly with the 341° line. Notice that the only other vernier scale tick marks that line up well with the main scale are ±60 arcmin. Since the pointer lines up with the main scale at 341°, the reading from Figure 4 is 341.00°.
There are two ways to determine the reading if the zero on the vernier scale line is between two lines of the main scale. For the first method, take the line on the left side of the pointer on the vernier scale and subtract that value (in arcmin) from the value on the main scale that is to the right on the main scale. As an example, in Figure 5 the vernier pointer is between 342° and 343°; using the left blue arrow of the vernier scale results in
As we've seen here, vernier scales add precision to a standard scale measurement. While it takes a bit of getting used to, with a little practice, reading these scales is fairly straightforward. Vernier scales, whether they are direct or retrograde*, are read in the same fashion.
*A retrograde vernier scale has a larger spacing between its tick marks with N ticks for every N + 1 ticks on the main scale.

(posted 2024-06-24 15:04:13.903) Dear Sir/Madam,
I need to use LabVIEW to control the K10CR1/M. According to the official tutorial, this can be achieved by using the corresponding .NET controls of Kinesis and the appropriate property nodes to control the rotation. However, considering the development of more complex programs in the future, I do not want the .NET controls to appear during the program execution, as this would occupy my front panel space and affect the program’s running speed.
It seems that I am unable to make the .NET controls disappear simply by hiding the LabVIEW front panel controls. I would like to ask if there are other programming methods, such as using more fundamental subVIs or dynamic link libraries, to ensure that the program does not include .NET controls.
Thank you for your assistance.
Best regards,

I would like to use two rotators in a LabVIEW program. Is it possible to use the same APT for both of them?
(We are now working with one and everything works fine)
Thank you jcater
(posted 2021-05-05 05:05:39.0) Response from Jack at Thorlabs: Thank you for your inquiry. Our APT software can be used to control multiple units at once. In LabVIEW you will have to create a new control for each individual unit. Jose Marticorena

We have a pair of K10CR1, which is part of a testbench system in the lab, where the windows GUI is fine for controlling, them, however, The end product will be a small form factor Linux machine.
A little googling led me to https://www.thorlabs.com/software/apt/APT_Communications_Protocol_Rev_15.pdf
and https://github.com/UniNE-CHYN/thorpy, but nothing specific to the K10CR1 for Linux; What is the best resource for learning to move it programatically from Linux? DJayasuriya
(posted 2019-12-17 08:27:23.0) Response from Dinuka at Thorlabs: Hello, thank you for your query. Unfortunately, neither Kinesis, nor APT, nor their respective APIs are compatible with Linux. KDC10CR1 can be controlled from a Linux system only via serial commands. The documentation of Kinesis' & APT's serial communications protocol can be found on our website. We also have plenty of examples, internally, of scripts written in various languages (C++, Python, MATLAB, LabVIEW) which make use of these commands. If you would like copies of these example scripts, please contact your local technical support office. Andrew Hillier

(posted 2019-12-12 09:23:54.0) Response from Dinuka at Thorlabs: Hello, thank you for your feedback. The unit is designed to for USB 3 connection it can also be powered using a Micro B USB 2 connection. Yes this stage can be controlled using APT or Kinesis software. Hope this helps. user
(posted 2019-10-17 20:32:53.233) This is an amazing product. It provides flexible mounting options along with the utility of rotating optical elements.
However, I think that there should be a version of this product that allows for higher rotation speeds.
One such product (along with a piece of ground glass on an SM-threaded mount) would provide a complete solution for setting up a rotating diffuser, which is necessary in many systems for turning spatially coherent light into incoherent light. This would save customers the need of having to buy everything separetely and building the system from scratch. We would have the option of just buying that high-speed motorized rotation mount along with a piece ground glass -both from the Thorlabs catalog- and get our rotating diffusers without much more trouble.

Though we do not have an equivalent high speed version (with 1” aperture), just to let you know we do offer a high speed compact rotation mount such as the DDR25 that has optical threading which you could use to mount a ground glass and is cage compatible. Please feel free to contact your local tech support office if you would like to discuss further regarding your application and suitability. Richard Grzebieta

(posted 2019-05-29 10:18:50.0) Response from Radu at Thorlabs: Hello, Richard. I am not sure that I correctly understand what configuration you have in mind, but the answer can be found in the information posted in the "Specs" tab. In a nutshell, if that 22 N load will not be applying more than 140 mN*m about the axis of rotation or more than 1.5 N*m about axes located in the plane of rotation, then the stage should operate nominally and meet all of its other specifications. user

I'd like to use the K19CR1/M motor with an extension cable (1.8m) and the cable (1.5m) included in the delivery. Unfortunately the control software doesn't work properly anymore like this. Jogs still work but when I try to move to a defined angle I get a timeout error. Do you have an idea for a solution? user
(posted 2019-03-28 12:00:46.0) Response from Radu at Thorlabs: The fact that jogs run successfully while moves result in timeout errors tells us that the messages sent by K10CR1/M to your PC are not seen, even though K10CR1/M successfully reads the messages coming from your PC. That might be a consequence of high unidirectional losses at the junction between the two cables. I suggest that you replace them with a cable that is long enough to connect the two devices directly. There is significant variation in the quality of USB cables available on the market. A couple of the companies that we know to provide USB cables of consistent quality are CIE Group & Space Shuttle Hi-Tech, so it might be worth trying to source them from there. naveenballa

I have a labview related query. I am trying to use this motor to rotate my polarizer in steps and measure my signal after each rotation step. I am using APT controls with labview. I want to make sure the motor has stopped before I measure the signal. If anyone has an example code on how to implement this, please share. I can use a waiting step after each rotate command but I am looking for an alternative solution. Thanks! rmiron
(posted 2019-04-09 05:13:33.0) Response from Radu at Thorlabs: The "MoveRelative (int waitTimeout)" and "MoveAbsolute (int waitTimeout)" methods return upon the completion of the demanded move, provided that the waitTimeout parameter is larger than the time it takes the move to complete (in ms). Therefore, I suggest that you place one of these commands and the command for measuring the signal, in separate frames of a flat sequence. That will ensure that the stage is not moving when a measurement is taken and vice-versa. ckwjp327

I would like to ask if there is any difference using the USB2.0 and USB3.0 cable for K10CR1? Sometimes "FT_IO_ERROR" will be shown. the powered USB 3.0 hub is used to drive the K10CR1, also the mobile phone and USB relay board are also connected to the same hub?
Or any standard on the USB cable? As sometimes the power LED flashes but do not rotate.
Thank you very much! AManickavasagam
(posted 2018-08-24 05:42:50.0) Response from Arunthathi @ Thorlabs: Thanks for your query. For data exchange the K10CR1 would be USB 2 compatible, the unit has USB 3 port for providing sufficient power without the need for using external power supply. FT_IO_ERROR suggests that an error has occurred while reading the data from the device, like a USB disconnect has occurred.

(posted 2018-05-22 08:17:41.0) Response from Ben at Thorlabs: Thank you for your feedback. In future, I would recommend directly emailing your local Tech Support teams to resolve this issue.
You will need to ensure that you have called SetMoveAbsolutePosition(position) & assigned a 'position' value. This will then enable you to wire an Invoke Node for a MoveAbsolute(waitTimeout) command whereby the Timeout is a finite amount of time in which the move should return a MoveComplete message.
I will contact you to ensure this is working for you. mailfert

(posted 2017-05-11 18:48:39.027) I'm using the communication protocol to send commands to the K10CR1. Some of the messages are useful(such as home and jog), but I can't get some other messages work, such as MGMSG_MOT_MOVE_RELATIVE on pg.55 and MGMSG_MOT_MOVE_ABSOLUTE on pg.58. I think I have read the protocol carefully but can't figure out why. Can you send me an example(long version) on either of these commands with K10CR1？Thank you very much! bwood
(posted 2017-05-12 05:59:35.0) Response from Ben at Thorlabs:Thank you for using our feedback feature. The easiest way to generate serial communications examples is directly through Kinesis, our motion control software. Firstly, download the software and begin controlling the stage. If you can then open "File" then "Options". On the "Application Options" tab press Ctrl+APT on your keyboard. This will allow you to expose the serial commands Kinesis is using to control the K10CR1 in real time. From this point, you can effectively generate example messages for any possible function of the stage. I hope this methodology helps, but feel free to contact me at techsupport.uk@thorlabs.com, if you have any difficulties or further questions. joos

I am currently interfacing the K10CR1 with python using the APT.dll of the APT User version 3.3.6064.16307. I am assuming the hardwaretype HWtype is 50 because it is the only one to work but can you confirm me this please. I am also facing the following problem that the velocity parameters after initialisation with InitHWDevice() are too low (typically 0.017 °/s instead of 10°/s even though MOT_GetVelParams() returns good values) and I have to explicitly specify them using MOT_SetVelParams().
I don't have the problem with the controller TDC001 interfaced as HWtype 31. Can you help me on this ?

https://www.thorlabs.de/Software/Motion%20Control/APT_Communications_Protocol_Rev_18.pdf
Checking the details of this method on pg.38 this may stem from the conversion factors used in the Get/SetVelParams method for the K10CR1. Within pg.16 & 17 of the communications protocol we outline the conversion between microstep counting & 'real world' units of position, velocity & acceleration for various stepper-actuated stages. We unfortunately have not updated this document to include conversions for our K10CR1 stage. We will update the document to include these conversions & I will send you a copy directly. frolovtsev

Both serial numbers are recognized, however the command TLI_GetDeviceInfo always returns the TLI_DeviceInfo struct filled with information of the first device, only, independent if the given serialNo is the one from the first or second device. However, serialNo which does not correspond to any device lead to an error. Might this be a bug in the Kinesis software (1.6.0)?

Zoom- Full Bidirectional 360° Rotation
- SM1 (1.035"-40) Threading for Mounting Ø1" Lens Tubes
- Four 4-40 Tapped Holes for 30 mm Cage Systems on Each Side of Housing
- Compact Size: 4.21" x 2.60" x 0.84" (107.0 mm x 66.0 mm x 21.5 mm)
- Two SM1RR Retaining Rings Included
Adapters are available that allow the user to mount the K10CR2(/M) mount directly to a table, add a tapped platform, or integrate it into a 60 mm cage system. These adapters are sold separately below.
Table Mounting Adapter
The K10CR1A1 Mounting Plate is designed to mount the K10CR2(/M) rotation mount horizontally to an optical table or breadboard for use as a rotation stage. The plate comes with three 8-32 and three M4 button head screws for attaching an imperial or metric stage, respectively. Four slots accept 1/4" or M6 screws, which are ideal for securing the stage to a breadboard.

The K10CR2 attached to a K10CR1A1 Mounting Plate, with a K10CR1A2 adapter plate attached to the moving world.
Rotating Platform Adapter
When the stage is mounted horizontally, the SM1 mounting feature may not be needed. In these cases, the K10CR1A2(/M) adapter plate attaches to the surface of the rotating dial with two included 4-40 (M3) button head screws. This Ø1.81" (Ø46.0 mm) plate provides a central 3.0 mm groove and 6-32 (M3) taps for attaching Thorlabs' flexure stage accessories. In addition, an array of six 2-56 (six M2), six 4-40 (two M2.5 and four M3), eight 6-32 (four M3 and four M4), and one 1/4"-20 (M6) taps allow for a variety of optomechanical components to be attached, including GN05 (GN05/M) Goniometers, PM3 (PM3/M) Prism Clamping Arms, and T12X (T12X/M) and MS1 (MS1/M) Translation Stages.
60 mm Cage System Adapter
The K10CR1A3 is a bracket that attaches to the edge of the K10CR2(/M) mount and allows the rotation mount to be integrated into 60 mm Cage Systems. The K10CR1A3 comes with three 8-32 and three M4 button head screws for attaching the bracket to both imperial and metric stages.
Once the bracket is attached to the stage, one cage rod is slid through the Ø6 mm bore in the bracket. Slots on the other edge of the bracket allow the rotation mount to pivot outside of the cage system for installation of optics or other components, as shown in the photos to the right. The design limits the number of cage rods used in a cage segment containing the rotation mount to three. A 0.050" hex key is included for tightening the locking setscrews onto the cage rods.
Please note that the K10CR1A3 bracket mounts the stage inside the 60 mm cage system at a 7° angle. While a fixed 30 mm cage system can still be attached to the front and back faces of the K10CR2(/M), the 30 and 60 mm cage system rods will not be aligned, although the optic axes will be collinear.
