K-Cube™ NanoTrak® Active Auto-Alignment Controllers are a part of Thorlabs' new and growing Kinesis® line of high-end, compact motion controllers. The active auto-alignment controllers are designed to maximize the power throughput of an optical setup, including fiber-to-fiber and fiber-to-free-space systems. By driving a piezo-actuated stage to move the fiber tip in a circular scan pattern, the controller performs a power gradient search to determine the direction of peak power and positions the fiber for maximum throughput. Two high-voltage output channels provide the drive signal for the associated piezo actuators, eliminating the need for external piezo drivers. In combination with a multi-axis, piezo-driven stage, such as our 3-Axis NanoMax and 6-Axis NanoMax stages, a K-Cube active auto-alignment controller creates a complete, compact auto-alignment system (see the Application tab for more details).
The small footprint of this unit (121 mm x 60 mm x 47 mm) and quickly detachable mounting plate allow the K-Cube to be securely mounted to an optical table in close proximity to the system it controls. Each controller comes with a preinstalled detector. The KNA-VIS has a Si detector optimized for the visible spectrum (320 nm to 1000 nm), while the KNA-IR has an InGaAs detector for the infrared (900 nm to 1700 nm). The front of each unit features a power switch that, when turned off, saves all user-adjustable settings. Top panel controls enable convenient standalone operation, and the easy-to-read digital display allows the user to monitor the alignment.
USB connectivity provides easy 'Plug-and-Play' PC-controlled operation, and a suitable cable is included with each K-Cube NanoTrak controller (USB 3.0 type A to USB type Micro-B). Two software packages are available: Kinesis, which features new .NET controls that can be used by third-party developers working in compatible languages such as C, C# and LabVIEW™ to create custom applications, and our legacy APT software. For more details, please see the Motion Control Software, Kinesis Tutorials, and APT Tutorials tabs.
Optical Table Mounting Plate
Each unit comes with a mounting plate that clips onto the base of the module. The plate contains two magnets for temporary placement on an optical table and two counterbores for 1/4"-20 (M6) cap screws for a more permanent placement on the tabletop. Please see the Specs for a mechanical drawing of the table mounting plate and the Mounting Options tab for how to mount the plate.
Power Supply Options
The preferred power supply (multi-channel or hub-based) depends on the end user's application and whether you already own compatible power supplies. To that end and in keeping with Thorlabs' green initiative, we do not ship these units bundled with a power supply.
The TPS002 Power Supply Unit should only be used to power a single KNA-VIS or KNA-IR unit to avoid exceeding current limitations. The KCH301 or KCH601 USB Controller Hubs, available below, are ideal for applications involving multiple K-Cubes and/or T-Cubes. The KCH301 features three controller mounting bays while the KCH601 features six controller mounting bays. These K-Cube NanoTrak controllers occupy two mounting bays, so only the KCH601 hub can be used to power multiple K-Cube NanoTrak controllers. All compatible power supply options can be found below.

K-Cube Mounting Options
Two options are available to securely mount our K-Cube controllers onto an optical table. An optical table mounting plate, provided with every K-Cube, allows for a single controller to be attached to an optical table. Alternatively, three- and six-port USB controller hubs are offered (sold separately) that can mount and power our K-Cube controllers. These options are described in further detail below.
Optical Table Mounting Plate
Each K-Cube unit comes with a mounting plate that clips onto the base of the controller, as shown in the animation below. The plate contains two magnets for temporary placement on an optical table and two counterbores for 1/4"-20 (M6) cap screws for a more permanent placement on the tabletop. Please see the Specs tab for a mechanical drawing of the table mounting plate.
Kinesis USB Controller Hubs
Multiple units can be mounted and connected to a single PC by using the KCH301 or KCH601 USB Controller Hubs. They each consist of two parts: the hub, which can support up to three (KCH301) or six (KCH601) K-Cubes or T-Cubes, and a power supply that plugs into a standard wall outlet. K-Cubes simply clip into place using the provided on-unit clips, while current- and previous-generation T-Cubes require the KAP101 Adapter Plate, shown in the animation below. The hub vastly reduces the number of USB and power cables required when operating multiple controllers.

Unlike T-Cubes, every K-Cube includes a mounting plate that clips onto the base of the controller. The plate contains two magnets for temporary placement on an optical table and two counterbores for 1/4"-20 (M6) cap screws for more permanent placement on the tabletop.
Kinesis USB Controller Hubs
3- and 6-Port USB Controller Hubs allow multiple controllers to be connected to one PC for multi-axis applications. K-Cubes can be directly attached to the hubs while T-Cubes require a KAP101 Adapter Plate.

Introducing Thorlabs' Kinesis® Motion Controllers
A major upgrade to the former-generation T-Cubes™, the growing K-Cube™ line of high-end controllers provides increased versatility not only through the new Kinesis software, but also through an overhaul and update of their physical design and firmware. Note that the Kinesis NanoTrak controllers can also be controlled using our legacy APT software.
Every K-Cube controller includes a digital display. In addition to basic input and output readouts, this display hosts a number of menu options that include go-to-position commands, homing, velocity control, and jogging. The on-unit velocity wheel and menu button are used to scroll through the available options. Each unit contains a front-located power switch that, when turned off, saves all user-adjustable settings as well as two bidirectional SMA trigger ports that accept or output a 5 V TTL logic signal.
Please see the table to the right for a full comparison of the features offered by our new KNA-VIS and KNA-IR K-Cubes and previous-generation T-Cube fiber alignment controllers.

Kinesis USB Controller Hubs
Complementing our K-Cubes are our Kinesis USB 2.0 controller hubs. With two versions available for three or six K- or T-Cubes, these USB hubs are designed specifically for communication between multiple controllers and the host control PC. These hubs are backward compatible with our T-Cubes.
K-Cubes simply clip into place using the provided on-unit clips, while current- and previous-generation T-Cubes require the KAP101 Adapter Plate, shown in the animation to the below right. The hub vastly reduces the number of USB and power cables required when operating multiple controllers.

3- and 6-Port USB Controller Hubs allow multiple controllers to be connected to one PC for multi-axis applications. K-Cubes can be directly attached to the hubs while T-Cubes require a KAP101 Adapter Plate.
Thorlabs offers two platforms to drive our wide range of motion controllers: our Kinesis® software package or the legacy APT™ (Advanced Positioning Technology) software package. Either package can be used to control devices in the Kinesis family, which covers a wide range of motion controllers 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 .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.
Kinesis GUI Screen
APT GUI Screen
Our legacy APT System Software platform offers ActiveX-based controls which can be used by 3rd party developers working on C#, Visual Basic, LabVIEW™, or any Active-X compatible languages to create custom applications and includes a simulator mode to assist in developing custom applications without requiring hardware.
By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the Kinesis and APT controllers 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 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.
A range of video tutorials is available to help explain our APT system software. These tutorials provide an overview of the software and the APT Config utility. Additionally, a tutorial video is available to explain how to select simulator mode within the software, which allows the user to experiment with the software without a controller connected. Please select the APT Tutorials tab above to view these videos.

LabVIEW
LabVIEW can be used to communicate with any Kinesis- or APT-based controller via .NET controls. In LabVIEW, you build a user interface, known as a front panel, with a set of tools and objects and then add code using graphical representations of functions to control the front panel objects. The LabVIEW tutorial, provided below, provides some information on using the .NET controls to create control GUIs for Kinesis- and APT-driven devices within LabVIEW. It includes an overview with basic information about using controllers in LabVIEW and explains the setup procedure that needs to be completed before using a LabVIEW GUI to operate a device.

The APT video tutorials available here fall into two main groups - one group covers using the supplied APT utilities and the second group covers programming the APT System using a selection of different programming environments.
Disclaimer: The videos below were originally produced in Adobe Flash. Following the discontinuation of Flash after 2020, these tutorials were re-recorded for future use. The Flash Player controls still appear in the bottom of each video, but they are not functional.
Every APT controller is supplied with the utilities APTUser and APTConfig. APTUser provides a quick and easy way of interacting with the APT control hardware using intuitive graphical control panels. APTConfig is an 'off-line' utility that allows various system wide settings to be made such as pre-selecting mechanical stage types and associating them with specific motion controllers.
APT User Utility
The first video below gives an overview of using the APTUser Utility. The OptoDriver single channel controller products can be operated via their front panel controls in the absence of a control PC. The stored settings relating to the operation of these front panel controls can be changed using the APTUser utility. The second video illustrates this process.
APT Config Utility
There are various APT system-wide settings that can be made using the APT Config utility, including setting up a simulated hardware configuration and associating mechanical stages with specific motor drive channels. The first video presents a brief overview of the APT Config application. More details on creating a simulated hardware configuration and making stage associations are present in the next two videos.
APT Programming
The APT Software System is implemented as a collection of ActiveX Controls. ActiveX Controls are language-independant software modules that provide both a graphical user interface and a programming interface. There is an ActiveX Control type for each type of hardware unit, e.g. a Motor ActiveX Control covers operation with any type of APT motor controller (DC or stepper). Many Windows software development environments and languages directly support ActiveX Controls, and, once such a Control is embedded into a custom application, all of the functionality it contains is immediately available to the application for automated operation. The videos below illustrate the basics of using the APT ActiveX Controls with LabVIEW, Visual Basic, and Visual C++. Note that many other languages support ActiveX including LabWindows CVI, C++ Builder, VB.NET, C#.NET, Office VBA, Matlab, HPVEE etc. Although these environments are not covered specifically by the tutorial videos, many of the ideas shown will still be relevant to using these other languages.
Visual Basic
Part 1 illustrates how to get an APT ActiveX Control running within Visual Basic, and Part 2 goes on to show how to program a custom positioning sequence.
LabVIEW
Full Active support is provided by LabVIEW and the series of tutorial videos below illustrate the basic building blocks in creating a custom APT motion control sequence. We start by showing how to call up the Thorlabs-supplied online help during software development. Part 2 illustrates how to create an APT ActiveX Control. ActiveX Controls provide both Methods (i.e. Functions) and Properties (i.e. Value Settings). Parts 3 and 4 show how to create and wire up both the methods and properties exposed by an ActiveX Control. Finally, in Part 5, we pull everything together and show a completed LabVIEW example program that demonstrates a custom move sequence.
Part 1: Accessing Online Help
Part 2: Creating an ActiveX Control
Part 3: Create an ActiveX Method
Part 4: Create an ActiveX Property
Part 5: How to Start an ActiveX Control

K-Cube™ NanoTrak® Active Auto-Alignment Application
A K-Cube™ NanoTrak® Active Auto-Alignment Controller can be used in conjunction with a NanoMax Flexure Stage to create a continuous active fiber alignment system. Light from a K-Cube laser source is transmitted through the input fiber to the fiber end attached to the moving world of the stage. An output fiber is fixed to the stationary portion of the stage, and the light transmitted through the second fiber is fed into the power sensor on the NanoTrak controller.
The NanoTrak controller looks for the gradient in the power signal to determine the direction of peak power. This is achieved by scanning the stage in a circular path. As the input fiber is driven in a circle, the optical power coupling between the two fibers will fluctuate. The NanoTrak samples the power at multiple points around the test circle and then directs the piezos to move the stage in the direction of the highest signal. This process is continued until the highest power lies in the center of the circle and the power at every point on the circle is equal.
Continuous active alignment (Tracking Mode) can be used to maintain alignment in a setup, or the gradient search can be halted (Latched Mode) for next step assembly or R&D operations. The setup below can be used for fiber characterization and testing. If the output fiber is replaced with one of our Fiber Optic Couplers, the same setup may be used to maintain high power throughput to an entire fiber-based setup.

(posted 2020-09-01 11:22:30.513) This is a great system for aligning our pulsed laser into an optical fiber but, on it's own, the NanoTrak alignment algorithm doesn't work with our pulsed laser. We solved the problem by using a lock-in detector to convert the pulsed signal from the alignment photodiode to a CW signal.
It would be nice if you could build this functionality into the NanoTrak controller. I'm imagining a "Sync" BNC port on the controller that takes a sync signal from the laser. cwright
(posted 2020-09-03 08:19:44.0) Response from Charles at Thorlabs: Hello Andrew and thank you for your feedback! We understand there is increasing interest in using our alignment devices with pulsed sources and your suggestion is something I will present on our internal engineering forums for future design considerations. klee
