KVS30 Stage Shown in Fully Extended Position
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.
*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. A USB 3.0 type A to type Micro B cable is included with each KVS30(/M) stage.

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.

Thorlabs' Kinesis® software features new .NET controls which can be used by third-party developers working in the latest C#, Visual Basic, LabVIEW™, or any .NET compatible languages to create custom applications.
For a collection of example projects that can be compiled and run to demonstrate the different ways in which developers can build on the Kinesis motion control libraries, click on the links below. Please note that a separate integrated development environment (IDE) (e.g., Microsoft Visual Studio) will be required to execute the Quick Start examples. The C# example projects can be executed using the included .NET controls in the Kinesis software package (see the Kinesis Software tab for details).
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, pitch and yaw platforms, and goniometers. We also offer manual translation stages.
These stages incorporate piezoelectric elements in a variety of drive mechanisms. Our Nanoflex™ translation stages use standard piezo chips along with manual actuators. Our LPS710E z-axis stage features a mechanically amplified piezo design and includes a matched controller. The PD1 stage incorporates a piezo inertia drive that uses "stick-slip" friction properties to obtain an extended travel range. The Elliptec™ stages use resonant piezo motors to push and pull the moving platform through resonant elliptical motion.
Stepper Motor Stages
These translation stages feature removable or integrated stepper motors and long travel ranges up to 300 mm. The MLJ150 stage also offers high load capacity vertical translation. The other stages can be assembled into multi-axis configurations.
DC Servo Motor Stages
Thorlabs offers linear translation stages with removable or integrated DC servo motors. These stages feature low profiles and can be assembled in multi-axis configurations.
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.

This vertical translation stage provides precise, stable height adjustment with smooth, repeatable motion. The large 116.2 mm x 116.2 mm platform is capable of moving loads up to 7.0 kg at speeds up to 8.0 mm/s. When the stage is fully lowered, the platform height is 124.2 mm.
The unit features Up and Down buttons for controlling the stage. When closed-loop control is disabled or when the stage is powered off, a manual scroll wheel can be used for adjustment. The USB connector allows PC control using our Kinesis® software control suite.
Two I/O ports enable external bidirectional triggering (5 V TTL). Mating cables for these ports are available separately below. A power supply with a region-specific adapter plug is included with the stage.
Two cables are available to enable external triggering via the I/O ports on the KVS30(/M) stage. The CA3339 cable features a male BNC termination while the CA3439 has a male SMA termination. Both cables are 1 m (39") long.
