The KVS30(/M) Motorized Vertical Translation Stage is a DC servo-driven linear stage with integrated drive electronics. This stage provides precise, stable height adjustment over the full translation range. The stage motor is capable of moving loads up to 7.0 kg on a large 116.2 mm x 116.2 mm mounting platform with minimal pitch and roll deviation. Crossed-roller bearings and a steel scale linear encoder ensure accurate positioning with high repeatability. See the Specs tab for complete specifications.
The top plate has twenty-five 1/4"-20 (M6) taps and sixteen 8-32 (M4) taps for mounting optomechanical subassemblies. The base of the unit has four through holes that accept 1/4"-20 or M6 screws for mounting to a breadboard or optical table; the holes are spaced such that both imperial and metric breadboards are compatible. The unit is supplied with a region-specific power supply with an input of 100 to 240 VAC. The power connector on the unit includes a locking mechanism to avoid accidental removal of the cord. Note that the power supply unit (PSU) should be connected to the stage before connecting the PSU to a power outlet. A USB cable for controlling the stage via PC is also included.
Local Control
Up and Down buttons on the side of the unit can be used to translate the stage when the motor output is enabled. Alternatively, a manual scroll wheel on the side of the unit can be used to adjust the stage height when closed-loop position control is disabled or the stage is powered off. If the stage is connected to a PC running the Kinesis software while using the manual adjustment wheel, any adjustments will be reflected in the position window of the Kinesis GUI. To enable or disable closed-loop position control, either hold the Up and Down buttons simultaneously until the Status LED flashes or change the setting in the Kinesis software when the unit is connected to a PC.
External Control
A USB port on the side of the stage allows it to be connected to a PC and controlled using our Kinesis® software suite. This software package features new .NET controls that can be used by 3rd party developers working in the latest C#, Visual Basic, LabVIEW, or any .NET compatible languages to create custom applications. Parameter settings can be adjusted on the PC and stored in non-volatile memory within the unit itself. When the unit is next powered up, these settings are applied automatically. Please see the Kinesis Software and Kinesis Tutorials tabs for more details. External bidirectional triggering is possible using the two I/O ports on the unit.

Thorlabs' Kinesis® software can be used to control devices in the Kinesis or APT™ 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 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.
By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the APT and Kinesis 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 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.

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.

 (posted 2024-04-04 08:58:23.103) Hello,
Why this product has way better repeatibliity (0.12microns) than M30XY/M? I thought they have same technology spolineni
 (posted 2024-04-10 05:31:47.0) Thank you for your inquiry. The better repeatability of the KVS30 is a result of its unique design and construction, which includes features such as crossed-roller bearings and a high-resolution linear encoder. I will personally contact you to offer more detailed information on this topic. Ludo
 (posted 2021-03-11 06:27:52.253) I'll (partially) answer my own question: "can this stage be used with Linux?" It seems that yes (see Charles' answer to feedback from "user" below), but the Kinesis software provided by Thorlabs is only Gate$' Micro$oft compatible. Using this stage with Linux requires the end user to first understand the APT communication protocol (nice from Thorlabs to provide this documentation) and write the code to implement the protocol, adjust PID parameters and perform tests. This prompts a new question: the APT protocol documentation doesn't list the KVS30, which is the equivalent controller one should refer to? cwright
 (posted 2021-03-12 11:03:59.0) Response from Charles at Thorlabs: Hello Ludo and thank you for your feedback. I will forward this on and ensure that the command protocol is updated. I will also contact you directly to give you a list of commands which can be used. This is a DC servo driven stage so the commands will typically align with those of the TDC/KDC. Mikkel Bregnhøj
 (posted 2020-10-03 03:21:54.373) Dear Thorlabs
Your KVS30/M Z-stage looks to be the perfect platform for reflection SFG measurements, and other multi-beam nonlinear optic techniques where dynamic control of the sample height is essential.
However, the minimal platform height of 12.5 cm is a little too heigh for the physical space on our tightly packed optical table.
Could you consider designing a version that is somewhat lower, but with approx. the same dynamic travel range and specs? One can always raise the platform, but lowering it is impossible.
Kind regards
Mikkel Bregnhøj DJayasuriya
 (posted 2020-10-06 08:34:33.0) Hello Mikkel, Thank you for getting in touch with us. Reducing the platform height with the current design would be a bit tricky due to the motor and bearing limits. I will get in touch with you directly top discus your application. user
 (posted 2020-02-29 12:53:25.613) Too bad these motorized instruments are not OS agnostic, which means I cannot put it into a system where OS is dictated by DUT. Make your products like the FW102C, built-in FTDI RS232 controller, so I can send text commands from any OS to operate the equipment. cwright
 (posted 2020-03-03 06:01:47.0) Response from Charles at Thorlabs: Thank you for your feedback. While this device does not have a dedicated port for such communication, you can control this device with text commands via the RS232 standard.
There are FTDI drivers which allow for interfacing with a virtual COM port, which allows for OS agnostic operation through our communication protocal document. You can view this communications protocol here:

Motorized Linear Translation Stages
Thorlabs' motorized linear translation stages are offered in a range of maximum travel distances, from a stage with 20 µm of piezo translation to our 600 mm direct drive stage. Many of these stages can be assembled in multi-axis configurations, providing XY or XYZ translation. For fiber coupling applications, please see our multi-axis stages, which offer finer adjustment than our standard motorized translation stages. In addition to motorized linear translation stages, we offer motorized rotation stages and goniometers. We also offer manual translation stages.
Piezo Stages
These stages incorporate piezoelectric elements in a variety of drive mechanisms. ORIC® stages incorporate piezo inertia drives that use "stick-slip" friction properties to obtain extended travel ranges. Our Nanoflex™ translation stages use standard piezo chips along with manual actuators. Elliptec® stages use resonant piezo motors to push and pull the moving platform through resonant elliptical motion. Our LPS710E z-axis stage features a mechanically amplified piezo design and includes a matched controller.

Direct Drive Stages
These low-profile stages feature integrated brushless DC servo motors for high speed translation with zero backlash. When no power is applied, the platforms of these stages have very little inertia and are virtually free running. Hence these stages may not be suitable for applications where the stage's platform needs to remain in a set position when the power is off. We do not recommend mounting these stages vertically.
