(
) next to the Item # below. A compatible ±15 V power supply (either open frame or enclosed), command cable(s), and optional mounts are sold separately below. For a list of which power supplies, cables, and mounts to use with which galvos, see the Galvo Compatibility tab.
The user must provide a function generator or other analog voltage output device in order to operate the servo drivers. The mirrors are offered with one of three coatings: a custom broadband protected silver coating, a coating for 355 nm, or for 1064 nm, as shown in the table to the right. Additional custom coatings are available upon request. Please contact Tech Support for more details. We also offer dual-axis systems that use the QS series galvos as well as complete scanning systems.
Servo Driver Board
These closed-loop servo drivers interpret the signals from the position-detecting system inside the motor and produce the drive voltage required to rotate the mirror to the desired position. High bandwidth ensures that analog command waveforms are followed with speed and accuracy.
Both drivers feature proportional-integral-derivative (PID) servo driver circuits with advanced current damping for high performance. The drivers incorporate low-noise components to maximize the signal-to-noise ratio for better accuracy and low-drift components to reduce the effects of temperature variation. A notch filter is selected and tuned for each unique mirror-galvo combination to maximize system bandwidth for faster, more accurate scanning. These systems are ideal for use in applications including step-and-hold positioning, vector positioning (e.g., laser marking), and raster positioning (printing or scanning laser microscopy).
Servos are optimized for high-speed, precise positioning for all applications. Servos for scanners with 4 or 5 mm and ≥15 mm maximum beam diameters additionally feature dual-output power amplifiers to keep power supply requirements modest for larger motors without sacrificing performance. Servo driver circuits provide soft start/stop operation, open circuit AGC fail, and over/under-voltage protections. Onboard status LEDs indicate servo status and fault conditions and a diagnostic port provides position, velocity, error, and current information. Each driver-galvo-mirror set is tested and tuned to specification. The unique serial number of the galvanometer is noted on its associated driver board. Note that the X and Y drivers are matched to their respective servos and are not interchangeable.

Galvanometer Motor/Mirror Assembly
The system consists of a galvanometer-based scanning motor with a mirror mounted on the shaft and a detector that provides positional feedback to the control board. The moving magnet design for the QS and QG series of galvanometer motors were chosen over a stationary magnet and rotating coil design in order to provide the fastest response times and the highest system resonant frequency. The position of the mirror is encoded using an optical or capacitive sensing system located inside of the motor housing.
Due to the large angular acceleration of the rotation shaft, the size, shape, and inertia of the mirrors become significant factors in the design of high-performance galvanometer systems. Furthermore, the mirror must remain rigid (flat) even when subjected to large accelerations. All these factors have been precisely balanced in our systems in order to match the characteristics of the motor and maximize performance.
The optics are secured to the motor/mirror assembly by a flexure clamp. The positions of the optical mount are set at the factory and should not be changed by the user.
System Operation
The servo driver must be connected to a DC power supply, the galvanometer motor, and an input command voltage source (the monitoring connection is optional). For continuous scanning applications, a function generator with a sine wave output is sufficient for scanning the mirror over its entire range. For more complex scanning patterns, a programmable voltage source such as a DAQ card can be used. User-generated motion trajectories with smooth acceleration profiles are preferred; uncontrolled steps should be avoided if possible. Please note that these systems do not include a power supply (sold separately below), function generator, or DAQ card. The drivers below are factory configured for a 0.22 V/° (QS series), 0.5 V/° (QG5 series), or 0.67 V/° (QG4 series) ratio between the input voltage and mirror position, as well as an input voltage of ±5 (QS series) or ±10 VDC (QG series). Drivers configured for 0.44 V/° and ±10 VDC are available upon request; please contact Tech Support. The control circuit also provides monitoring outputs that allow the user to track the position of the mirror. In addition, voltages proportional to the drive current being supplied to the motor and the difference between the command position and the actual position of the mirror are supplied by the control circuit.
Closed-Loop Mirror Positioning
The angular orientation (position) of the mirror is measured using an optical or capacitive sensing system, which is integrated into the interior of the galvanometer housing, and allows for the closed-loop operation of the galvanometer mirror system.
The table below illustrates how to assemble a galvo system. After picking the galvo needed, choose the applicable power supply and cable set to match. Open frame power supplies require the cables to be soldered into the system, while enclosed power supplies allow the cables to directly connect to the system. A user-supplied controller will also be needed for this system.

(posted 2024-07-29 10:55:25.0) Thank you for reaching out to us with this inquiry. You asked the following: Do you have a detailed test report (QC report) for the galvanometer motor? Include parameters such as repeatability, linearity, temperature drift, etc.
This is likely something we can get for you, as each galvo is tested for these types of parameters. I have contacted you directly to inquire about which specific tests you need, and whether or not we can provide all of them. cdolbashian
(posted 2024-06-04 02:02:55.0) Thank you for reaching out to us with the following inquiry: Hello, I bought the QS20X-AG galvanometer. I would like to ask, if I want to place it directly on the optical table vertically and rotate it around the vertical z-axis during work, what kind of mounting base do I need? I have reached out to you directly to recommend some parts which would potentially work for your application. user
(posted 2024-06-03 10:56:01.51) Can you help to mount and tune a custom optics on the QS20X-AG rotor? Hongrae Kim
(posted 2024-04-29 13:28:32.56) I'm using a galvo mirror from Thorlabs, QS7X-AG, and I found that QS7X-AG has a slight vibration about +- 10 micro radians even when at rest.
I found that the stated repeatability for this model is 10 micro radians according to Thorlabs website.(https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=14115&pn=QS7X-AG#14129)
Does the term "repeatability" mean that its vibration is about 10 micro radians?
And is 10 micro radians a minimum value for "repeatability"? (My galvo's vibration is about 20 micro radians. So I wonder whether this value is within an acceptable range...) cdolbashian
(posted 2024-05-06 10:49:41.0) Thank you for reaching out to us with this inquiry. I would not expect you to see such vibrations (corresponding to uV of signal). When we measure stable vibrations in the lab, our measured values are consistently lower. Perhaps this has to do with your power supply. I have contacted you to troubleshoot your issue. WeiChi Hung

2. 請問此振鏡是否只能使用Analog Output來控制電壓以控制旋轉角度? cdolbashian
(posted 2024-03-18 11:24:26.0) Thank you for reaching out to us with the following, translated, inquiry:
1. What is the unit and range of Pin1-Galvo Position Output in the J-12 area in Section 7.3 of the Servo Amplifier Manual
2. what is the meaning of the angle or position represented by its value and what is the value of the Galvo Position in the initial state?
4. Can this galvanometer only use Analog Output to control the voltage to control the rotation angle?.
The answers to your questions are as follows:
1. +/-5V with the scaling of 0.22V/°Optical
2. The voltage output of the diagnostic pin is +/-5V corresponding to 0.22V/° optical. The optical angle is twice the mechanical angle (due to the law of reflection, whereas a beam reflecting will have an equal incident and outgoing angle).
The initial state corresponds to 0V. The mirrors are set to a nominal factory set zero position, such that that a beam input parallel to the mounting surface will be reflected and output as a parallel beam which has been turned 90° and displaced vertically, as shown here: https://www.thorlabs.com/_sd.cfm?fileName=MSTN000971-E0W.pdf&partNumber=QS15XY-AG
3. Yes, the galvonometer moves linearly with analog input voltage following the relationship of 0.22V/°
I have contacted you directly with more information here. Byung-Jin Lee
(posted 2023-12-08 15:57:50.31) I have a question about QS30X-Y1 motor. I want to rotate an attachment with an inertial load of about 10g*cm^2 from 0 to 2 degrees quickly and accurately. The input signal is DC, and the increment is basically a square wave, but could be sin or exponential. How fast and accurately can I rotate it using this motor? A delayed or slightly smaller actual motor rotation angle compared to the input signal is not a problem for us as long as it is constant from input to input. ksosnowski
(posted 2023-12-11 10:39:20.0) Thanks for reaching out to Thorlabs. Each galvo driver card is tuned to be specifically paired with the same motor/mirror at all times. A special load like this would require special tuning during production. Since a square wave's rising slope is quite steep, most voltage sources can switch the square wave faster than the galvo driver's max slew rate. When this happens, the galvo will draw the max possible current it can, and will experience increased error while the galvo catches up to the command point. This leads to a constant velocity or triangular wave position output. The choice of waveform and associated slope of the waveform strongly effects whether or not you'll hit a point where your waveform changes voltage faster than the galvo driver can. We do specify a small step response which is limited by the circuit settling time however above 0.4 degrees the magnitude of the command may require enough driving current to place something like 2 degrees at the start of the large signal regime which is slew-limited. Changing the waveform may change the settling time at this magnitude however the performance is in any case still stable and repeatable. Andrew Chuang
(posted 2023-08-22 22:24:47.64) Do you offer longer length cable?
What's the gauge size of the line you are using ? ksosnowski
(posted 2023-09-13 11:05:52.0) Hello Andrew, thanks for reaching out to Thorlabs. Each of the QS series galvos comes with a spare connector kit for creating custom length cables. Longer command cables may pick up additional noise and using too long of a power cable could pose a higher impedance and reduce the supply power. Depending on the noise a filter might be used on the command cable to eliminate this or a higher current power supply may be used to overcome power losses. The power cable uses 24AWG and the command cable uses 22AWG conductors. I have reached out directly to discuss your application in further detail. Andrew Chuang
(posted 2023-03-16 19:55:29.277) Hello...

(posted 2023-04-03 05:54:39.0) Thanks for reaching out to Thorlabs. As the GPWR15's operating instructions are engraved on the device front panel, we have not traditionally had a manual for this unit. However we are currently working on additional documentation to support this. I have contacted you directly to discuss this application in more detail. Daniel Brown

(posted 2021-10-12 23:13:07.867) Hi,
I need a galvo motor like QS20Y-AG.
What will be the step response for 2 optical degrees?
Can I send a desired motion and ask if it possible with your galvo motor and driver?
Thanks,
Ofir Kalif cdolbashian
(posted 2021-10-28 04:16:07.0) Thank you for reaching out to us at Thorlabs, Ofir! The speed of the step depends on the driving current. I have contacted you directly to discuss the particular motion you are attempting. Following our discussion, we have determined that with the proper ramping function applied to the current (rather than an uncontrolled step function), you are able to easily achieve the motion desired! Jaeyong Kim
(posted 2021-09-02 17:19:13.7) I want to use this one for a laser external shutter.
What is the full angle moving time? cdolbashian
(posted 2021-09-10 11:12:23.0) Thank you for contacting Thorlabs! We would never recommend using a galvo as a replacement for a shutter. A shutter should have a safety feature where the unpowered state is in the closed position. These galvos would simply stop moving if unpowered, and would not reset to any particular state.
Regarding the "full angle moving time", this would depend on the drive current. I have contacted you directly inquiring about your particular configuration. |

- Dowel Hole/Slot Design for Repeatable Precision Mounting on MT Translation Stages
- Compatible with GHS003(/M) Heat Sinks
Thorlabs' QSMx(/M) mounts provide a convenient solution for mounting the QS and QG single-axis galvo systems sold above. The holes available for mounting on our posts or translation stages in either verical or horizontal orientations are shown in the diagrams below. The galvo is secured using a two-piece clamp, allowing it to be installed without passing the sensitive mirror through the mount. For applications with highly variable drive signal waveforms that require additional heat dissipation, all mounts are compatible with the GHS003(/M) heat sinks. Refer to the table above to select the compatible mount for each single-axis galvanometer.
A plastic insulating shim (0.002" thick) is included with QSM3(/M) mounts to protect the capacitive position detector from electrical noise. It is recommended that users wrap the shim around the galvo prior to mounting for electrical isolation.
