This Motorized Pitch and Yaw Platform provides ±2.5° of adjustment in pitch and ±4.0° in yaw. It is designed for use with loads up to 2.0 kg (4.40 lbs), such as lasers, cameras, and 3-axis stages. The actual maximum load will depend on the positioning of the load on the platform (see the table to the right or the Specs tab for more details). The 112.0 mm x 115.0 mm (4.41" x 4.53") top platform is equipped with an array of 1/4"-20 (M6) threaded mounting holes on 1" (25 mm) centers.
The base of the pitch and yaw platform is provided with eight through holes for attachment to metric or imperial optical tables and breadboards. The through holes allow the tapped holes on the unit to be in line with the optical table hole pattern or midway off the optical table hole pattern. The unit can also be secured at any arbitrary position by using two CL6 table clamps (sold separately).

Engravings on the platform indicate the pitch axis and yaw center to help minimize crosstalk.
Included and Compatible Actuators
The two included Z812B DC servo actuators feature a 0.5 m
(1.6') cable length. They provide a minimum achievable incremental movement of 7.13 arcseconds in pitch and 15.71 arcseconds in yaw. The actuators attach to the stage using a flexure clamp that tightens around the Ø9.5 mm (Ø3/8") barrel. If desired, the Z812B actuator can be replaced by any manual or motorized 13 mm (0.47") actuator that includes a Ø9.5 mm (Ø3/8") barrel, including stepper motor actuators and manual micrometers.
Controller Options
Thorlabs recommends using two KDC101 T-Cube™ Motor Controllers, available below. Each KDC101 provides control for a single axis, with or without a PC. It is compatible with Thorlabs' APT™ software, which supplies out-of-the-box stage control from a PC and enables support for common programming interfaces like LabVIEW, LabWindows, and ActiveX. A USB cable is included with each KDC101. For more information or to download our APT™ software, please see the APT Software and APT Tutorials tabs.

How to Calculate the Linear Displacement per Encoder Count
For the Z812B, there are 512 encoder counts per revolution of the motor. The output shaft of the motor goes into a 67:1 planetary gear head. This requires the motor to rotate 67 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm.
The linear displacement of the actuator per encoder count is given by
512 x 67 = 34,304 encoder counts per revolution of the lead screw,
whereas the linear displacement of the lead screw per encoder count is given by
1.0 mm / 34,304 counts = 2.9 x 10-5 mm (29 nm).

The APT™ (Advanced Positioning Technology) family covers a wide range of motion controllers ranging from small, low-powered, single-channel drivers (such as the T-Cubes) to high-power, multi-channel, modular 19" rack nanopositioning systems (the APT Rack System).
All controllers in the APT family share a common software platform, the 'APT System Software', which is available on our APT software download page. A support package, containing a wealth of information on using and programming these Thorlabs products is also available.
By providing this common software platform, Thorlabs has ensured that users can easily mix and match any of the 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 the low-powered, single-axis to the high-powered, multi-axis systems and control all from a single, PC-based unified software interface.
The APT System Software allows two methods of usage: graphical user interface (GUI) utilities for direct interaction 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 are 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, which are also available on the software cd included with the controllers.
Software
APT Version 3.21.6
Includes a GUI for control of Thorlabs' APT™ system controllers, as well as a wealth of support information in the form of handbooks, help files, tutorial videos, and FAQs.
Also Available:
- Communications Protocol

APT GUI Screen
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 2022-09-02 09:52:07.84) Hi,
This product is great; however, something we came across in a recent design review for our specific application is whether the motorized actuators must mount in this specific orientation with respect to stage movement.
More specifically - our application would benefit from the pitch and raw actuators ability to mount vertically such that they are perpendicular rather than parallel with the pitch axis.
Is something like this a possibility? Perhaps there is an alternative product which satisfies this need?
Thanks!
Jesse cwright
 (posted 2022-09-06 10:51:33.0) Response from Charles at Thorlabs: Thank you for contacting us. We are happy you have found the product useful and welcome the feedback. Unfortunately it is not possible to adapt this stage such that the adaptors are vertical and we do not currently have another stage which could serve as an alternative with this configuration. chf7
 (posted 2018-09-18 14:17:29.77) Is this product vacuum compatible? AManickavasagam
 (posted 2018-09-19 04:40:01.0) Response from Arunthathi @ Thorlabs: Thanks for your query. PY004Z8 is not vacuum compatible as the stage is made of Aluminium and it is anodised. Also, the grease used is not suitable to use in vacuum conditions. |
