The MLS203/MZS500-E motorized XYZ microscope stage system presents a 3D positioning solution for applications such as Z-axis slicing or 3D image collection, including laser scanning microscopy. It provides active feedback to compensate for thermal changes and other factors that might lead to stage drift. The closed-loop, active feedback ensures correct positioning with submicron repeatability and Z-axis resolution of 25 nm, making the XYZ stage system ideal for applications that require highly accurate focus control. To build a complete XYZ motorized microscopy stage package, purchase both the MLS203 XY Scanning Stage and the MZS500-E Z-Axis Stage along with their respective controllers and the mounting brackets for the MLS203 stage. Optional Z-axis stage accessories can also be purchased below. The table below outlines the items that should be purchased to form a complete XYZ stage package for various microscopes.
XY Scanning Stage
The MLS203 XY Scanning Stage is the first of the two components needed to construct the XYZ microscope stage. This stage has been designed as a drop-in replacement for the manual stage found on select Nikon, Olympus, and Zeiss microscopes or for use with Thorlabs' Cerna microscopes to provide motorized XY positioning of microscopy samples. Characterized by high-speed scanning capabilities and high positional accuracy of <3.0 µm, this stage is ideal for manually or automatically positioning a wide range of specimens and samples in many types of microscopy or imaging techniques and applications. To incorporate the XY stage into a microscope imaging system, you must use one of the mounting brackets provided below; the type of bracket will be dependent on the microscope being used. Alternatively, we also offer adapters to bolt the XY scanning stage to an optical table or breadboard for use in typical photonics applications or in a custom microscope setup.
Z-Axis Piezo Stage
The MZS500-E Z-Axis Piezo Stage is the second of the two components needed to construct the XYZ microscope stage. This low-profile, piezo-driven stage provides 500 µm of travel in the vertical (Z-axis) direction. The stage is sold with a closed-loop, piezo controller; together, the stage and controller provide computer-controlled Z-axis positioning and active location feedback. To incorporate the stage into the microscope imaging system, it must first be mounted to an MLS203 XY scanning stage using the provided cap screws. Please refer to the table below to verify which XY stage can mount the MZS500-E Z-axis stage. Once a compatible XY stage is chosen, select the compatible XY stage mounting bracket to incorporate the XYZ stage into your microscope imaging system.
Specimen Holders and Accessories
We offer a range of adapters to allow the positioning of microscope slides, Petri dishes, and mounted metalurgical specimens. The Z-axis piezo stage accepts a well plate directly. The MJC2 XY-Axis and MJC1 Z-Axis Joysticks are also available for both the MLS203 and MZS500 stages, respectively. Please see the details below.

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.
Software
Kinesis Version 1.14.40
The Kinesis Software Package, which includes a GUI for control of Thorlabs' Kinesis and APT™ system controllers.
Also Available:
- Communications Protocol
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
The following tutorial videos illustrate alternative ways of creating Method and Property nodes:
Create an ActiveX Method (Alternative)
Create an ActiveX Property (Alternative)
Visual C++
Part 1 illustrates how to get an APT ActiveX Control running within Visual C++, and Part 2 goes on to show how to program a custom positioning sequence.

 (posted 2021-09-20 11:20:20.11) Hello,
Our MZS500-E has problem that it couldn't zero-positioning.
When push the Zero positioning button,
The position value is -35.2432 um and Maximum voltage
I thought that this problem comes from positioning sensor calibration (green plate).
But, It doesn't has any feedback even manual file :)
How can I fix this problem? DJayasuriya
 (posted 2021-09-21 03:49:30.0) Thank you for your inquiry. We will get in touch with you directly to troubleshoot. jinjie pan
 (posted 2021-06-01 10:52:56.903) 我们从你们这里购买了MZS500-E这器材,但是我们自己不小心将其附带的接线弄丢了,还希望你们可以提供一下这个器材和控制器的接线的型号,我们好在购买一下,一根电源线我们型号找到了,但是另一根反馈线我们型号找不到,还希望你们可以提供一下,谢谢,希望得到您的回复。 cwright
 (posted 2021-06-02 09:20:55.0) Response from Charles at Thorlabs: Thank you for your query. A member of your local technical support team will reach out to help provide the cables you have misplaced. laura.waller
 (posted 2014-01-07 18:47:01.677) We can only get this working with matlab Active X if we use a 32 bit PC. Who uses 32 bits these days?!? Isn't there a 64 bit automation option that will interface with Matlab? msoulby
 (posted 2014-01-08 04:36:40.0) Response from Mike at Thorlabs: We are currently developing a 64bit software platform to replace our now old APT software which will be 64bit compatible. We are currently in an alpha test phase but hope to have an advanced beta version in the near future that we can send to customers to use. However you can use direct serial communication over a virtual comm port in order to talk directly to the controller on a 64bit machine. I have contacted you directly with details of the USB communication protocols we use and more details on its use. kelvin.wc.poon
 (posted 2013-07-15 15:15:41.773) This is a follow to the question below.
Does the max load for the stage (250g) include the weight of the accessory plates? We have weighed the latter and they are around 200g, leaving only 50g for our samples.
Another concern is the single spring/tension being the only point of contact for the plates. Any rapid XY movement makes the plate shift slightly. Is there a way to improve the stability? pbui
 (posted 2013-07-18 11:39:00.0) Response from Phong at Thorlabs: Thank you for your feedback. The absolute weight limit of the stage is 250g, so your sample should be 50g or less. Regarding the stability, as we mention in a note in the manual on page 13, heavier loads may be unstable. We would recommend using a lower acceleration with a profiled stop to avoid this issue. cbrideau
 (posted 2013-06-24 21:08:06.623) Does the 250g weight limit of the MZS500 stage include the weight of the inserts such as the MZS500P4? bdada
 (posted 2011-11-03 11:33:00.0) Response from Buki at Thorlabs:
We appreciate your interest in our microscopy stages and your positive feedback about our products. We can certainly arrange for you to test our products. We have contacted you to continue this conversation. gcolarus
 (posted 2011-11-02 22:39:11.0) Hi,
I am very interested in purchasing your automated microscope stage (both x,y and piezo z) products as well as your filter wheels/shutters.
I notice that they are compatible with Micromanager from the Vale website. However, I can't seem to track down a group that is using your stages with MM.
Can you comment on the compatibility with MM or put me in contact with groups that have these stage components running in their labs with MM? How about Volocity or Metamorph? If possible, we would greatly appreciate a loaner unit and we could prepare a complete report as we have lots of experience with imperfect automated stages (companies shall remain un-named for now).
I am keen because I have been buying different components from Thor and have not been disappointed.

These Motorized XY Scanning Stages are required when using the MZS500-E Z-Axis Piezo Stage (sold below). When combined with the Z-axis piezo stage, it forms a versatile 3D translation stage for scanning across a sample with high precision in the X, Y, and Z axes. The MLS203-1 Stage is compatible with inverted and upright microscopes from Nikon and Olympus, as well as with upright Thorlabs Cerna microscopes; mounting brackets are required (sold below). The MLS203-2 Stage is directly compatible with Zeiss Axio Observer and Axiovert 40 microscopes; mounting brackets are not required.
The recommended controller for the XY scanning stages is the BBD302 Two-Channel Controller, which features Thorlabs' Kinesis® control and programming interface, enabling easy integration into automated microscopy applications. This controller is ideal for applications demanding operation at high speeds (hundreds of mm/s) and high encoder resolution (<100 nm). For greater flexibility, communication with the PC is supported using either a USB or RS232 interface.
The controller is supplied with a software development kit (SDK) in order to also support automated PC control of the MLS203 stages. This is useful to system integrators and other automation specialists who need to combine operation of the stage with other microscopy automation accessories. The fully documented SDK supports all major development languages running on Windows, such as LabVIEW, C++, and MATLAB, and comes in the form of ActiveX libraries or a conventional dynamic link library (DLL). Multiple units can be connected to a single PC using a USB hub; for example, the BBD302 Controller for the MLS203 XY stages and the controller supplied with our MZS500-E Z-Axis Stage Kit can be controlled simultaneously with a single PC. Please click here to view the full presentation for these Brushless DC Motor Controllers.

Please note that the MLS203-2 is directly compatible with Zeiss Axio Observer and Axiovert 40 microscopes. Mounting brackets are not required.
Additionally, there are two options for attaching an MLS203 stage to an imperial or metric breadboard to support home-built microscopes or general photonics applications. The MLSA01 Riser Plates, compatible with stage Item # MLS203-1, will raise the height of the stage by 1.24" (31.5 mm). The MLSA04 Adapter, compatible with stage Item #s MLS203-1 and MLS203-2, connects to the base of the stage, blocking the central aperture; however, it raises the height of the stage by only 0.03" (0.7 mm), making it well suited for height-limited applications.

The MZS500-E Z-axis stage and controller bundle includes a Z-axis stage and a closed-loop piezo controller. The piezo-driven stage provides 500 µm of vertical (Z-axis) travel, 25 nm of resolution, and a 0.5 lb (0.25 kg) max load capacity. The bundle includes everything needed for computer-controlled, Z-axis positioning and active location feedback. Please see the Specs tab for more information on the Z-axis piezo stage.
To incorporate the Z-Axis Stage into a system, it must first be mounted to an MLS203 series XY stage (shown to the upper far right). These two products combined present a versatile 3D solution for translating samples over a long range or across a sample with high precision. The stage can also be directly fitted with a multiwell plate (shown to the upper right); additional accessories can be found below.
The controller included with the stage is a single-channel, high-power (150 V, 500 mA), benchtop piezo controller for open- and closed-loop nanometer position control. Flexible software settings make this controller suitable for driving a wide range of third-party piezo products. In addition, USB connectivity provides easy plug-and-play PC operation; multiple units can be connected to a single PC via a standard USB hub for multi-axis motion control applications. Coupling this with the user-friendly APT™ software allows the user to quickly get up and running. Advanced custom motion control applications and sequences are also possible using the extensive ActiveX® programming environment. These ActiveX Controls can be incorporated into a wide range of software development environments including Labview, C++, and Matlab. Please see the Specs tab for more information on the Z-axis stage controller.

The MJC2 Joystick Console has been designed for microscope users and provides intuitive, tactile, manual positioning of the MLS203 Stages and other XY translation stages. The console features a two-axis joystick for XY control. In most applications, the default parameter settings saved within the controller allow the joystick to be used out-of-the-box, with no need for further setup, thereby negating the requirement to be connected to a host PC and allowing true remote operation. Parameter settings can also be reprogrammed and saved to a paired controller using a PC, allowing the controller to be disconnected from the computer and remote operation continued.
The MJC2 Joystick is compatible with our Benchtop Brushless DC Servo Controllers, Rack-Mounted Brushless Controller, and Stepper Motor Controllers. The joystick has both a Mini-DIN and a USB Type-C port and is shipped complete with two cables, a 6-pin Mini-DIN plug to plug cable and a USB 3.1 Type-A to Type-C cable, for use with these controllers as well as setups utilizing the USB HID class. For more information about configuring and setting up the joystick over USB HID, please see the manual by clicking on the red Docs icon () below. If you intend to use the joystick with a legacy BBD10x series unit, please contact Tech Support for a compatible cable.
