Thorlabs offers the popular Ultra-Stable KS1 Ø1" mirror mount in a motorized version. The KS1-Z8 mount comes with two of our Z812 DC Servo Motors and includes a 1/4"-80 threaded adjuster, which allows for greater pitch and yaw adjustment over standard two adjuster mounts. The mount is fabricated from black anodized aluminum.
The two Z812 DC Actuators are equipped with commercial grade internal limit switches to provide over drive protection. The motors also have an encoder to provide 6 arcsec angular resolution. Our TDC001 single channel T-Cube DC servo motor controller is ideally suited for use with this Z812 motorized mount. Appropriate power supplies for the TDC001 are below. Note that if you will be using a Z8 series DC Servo Motor with a previously purchased TDC001, you may need to update your firmware to version 1.0.10 or later. This update is included in the APTServer Software download.
Please refer to the Actuator Specs tab for more information on these motorized actuators.
Calculating the Linear Displacement per Encoder Count
For the Z812, 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 KS1-Z8 features an Ultra-Stable KS1 Ø1" mirror mount and combines it with two Z812 Series DC Motor Actuators. Higher precision adjustments can be made with the motorized actuators than otherwise possible with manual adjusters. The mount also features one 1/4"-80 adjuster, which allows for greater pitch and yaw adjustment over standard two adjuster kinematic mounts, while also providing Z-translation.
The TDC001 DC Servo Motor Controller is the recommended controller for the KS1-Z8. The controller is single channel and provides a control panel on top, which offers Move/Jog buttons to move the actuator's leadscrew in discrete steps and a Velocity Potentiometer to move the leadscrew at various velocities. This T-Cube controller can also be connected and controlled with a computer via USB 2.0. Note that the controller does not include a power supply, but our compatible supplies are below.

A location specific power adapter is shipped with the TPS001 based on your location.
The preferred power supply (i.e., single channel, multi-channel, or hub-based) for your TDC001 DC Motor Controller depends on your application and whether you already own compatible power supplies. Thus, Thorlabs does not prebundle a power supply with your purchase of the TDC001.
The TDC001 T-Cube Controller can be powered using either a TPS001 or a TPS008 power supply or the TCH002 T-Cube Hub and Power Supply. The TPS001 powers a single T-Cube, while the TPS008 can power up to 8 T-Cubes. Both units plug into a standard wall outlet and provide +15 VDC. The TCH002 Hub and Power Supply consists of two parts: the hub, which can support up to six standard-footprint T-cubes, and a power supply that plugs into a standard wall outlet and powers the hub, which in turn powers all the T-cubes connected to the hub.
