These high-speed Scanning Galvanometer Mirror Positioning Systems are designed for integration into OEM or custom laser beam steering applications that utilize laser beams smaller than 5 mm in diameter. Each system includes a single- or dual-axis galvo motor and mirror assembly, associated driver card(s), and driver card heatsink(s). A low noise, linear PSU (GPS011) and motor/mirror assembly heatsink (GHS003) are available separately.

Galvo Motor/Mirror Assembly
The galvo consists of a galvanometer-based scanning motor with an optical mirror mounted on the shaft and a detector that provides positional feedback to the control board. The moving magnet design for the GVS series of galvanometer motors was 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 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 galvo systems. Furthermore, the mirror must remain rigid (flat) even when subjected to large accelerations. All these factors have been precisely balanced in our galvo systems in order to match the characteristics of the galvo motor and maximize performance of the system.

The mirrors are available from stock with silver, gold, broadband or high power dual band coatings. Custom coatings (e.g., aluminum) are available on request. Please contact Tech Support for more details.

Scanning Galvo Mirror Assembly and Driver Board
All Thorlabs scanning galvo mirror systems feature a mounted single or dual axis mirror/motor assembly and driver card(s). Shown to the left is the GVS301 1D galvo mirror and driver card with heatsink. The mirror assembly feature multiple mounting holes and a rotatable collar mount for the mirror/motor. These small 5 mm galvo mirrors feature a plug style connector to the mirror assembly. Please see below for additional mounting options and accessories.

Servo Driver Board (All Systems)
The Proportional Derivative (PD) servo driver circuit interprets the signals from the optical position detecting system inside the motor and then produces the drive voltage required to rotate the mirror to the desired position. The scanner uses a non-integrating, Class 0 servo that is ideal for use in applications that require vector positioning (e.g., laser marking), raster positioning (printing or scanning laser microscopy), and some step-and-hold applications. Furthermore, the proportional derivative controller gives excellent dynamic performance. The circuit includes an additional current term to ensure stability at high accelerations. The same driver board is used in all our galvo systems.

System Operation
The servo driver must be connected to a DC power supply, the galvo motor, and an input voltage source (the monitoring connection is optional). For continuous scanning applications, a function generator with a square or sine wave output is sufficient for scanning the galvo mirror over its entire range. For more complex scanning patterns, a programmable voltage source should be used. The ratio between the input voltage and mirror position is switchable, either 0.5, 0.8 or 1. When set to 0.8, the ±10 V input will rotate the mirror over its full range of ±12.5°. 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 optically encoded using an array of photocells and a light source, both of which are integrated into the interior of the galvanometer housing. Each mirror orientation corresponds to a unique ratio of signals from the photodiodes, which allows for the closed-loop operation of the galvo mirror system.

The systems can be driven to scan their full mechanical range of ±12.5° at a frequency of 100 Hz when using a square wave control input voltage or at 350 Hz when using a sine wave. For a single small-angle step of 0.2°, it takes the mirror 300 μs to come to rest at the command position.
The scan frequency range is DC to 1 kHz and the angular resolution is 0.0008° (15 μrad).

JP7 Volts/Degree Scaling Factor Control

JP7

Servo driver cards manufactured after October 2009 have a jumper which is used to set the Volts per Degree scaling factor. The cards are shipped with the scaling set to 1.0 V/°, where the max scan angle is 10°, and is compatible with driver cards manufactured before October 2009.

To set the maximum scan angle to ±12.5°, set the scaling factor to 0.8 V/° by placing a jumper across the pins as shown above. Similarly, the 0.5 V/° scaling factor is provided to allow the full scan angle to be achieved using small input signals. In this case, the input voltage should be limited to ±6.25 V max.

External Enabling of the Driver Board

The drive electronics can be configured for external enabling by placing a jumper across pins 2 and 3 of JP4.

JP4
JP4

Once this has been done, the user can enable or disable the drive electronics by applying a 5 V CMOS signal to J7 pin 4.

If a logic high or no signal is applied, the drive electronics will be enabled. If a logic low signal is applied, then the driver will be disabled.

Response from Tim at Thorlabs: Thank you for contacting us. Please check that the scaling factor is set correctly, check jumper 7 on the driver board (see page 19 of the manual). Also, please check that the correct board is connected to the correct motor, as each board is specifically tuned for each mirror. If they are swapped it may cause them to operate out of spec. We will contact you directly to continue troubleshooting.

There is something in my system that does not make sense. I have a plate ~23 cm from the galvo, and the full range of the scan in each axis is almost 15 cm (from -7.5V to +7.5 V), which corresponds to more than 30 degrees already. The galvo was purchased as a package with all the power supply and heat sinks. The voltage is supplied by a NI DAQ board (max +/- 10 V) and I did not change the factory settings, which should be 1 deg/V. So, I am not sure what I am missing...

Posted Date: 2012-08-06 08:36:00.0

Response from Jeremy at Thorlabs: Depending upon the noise component of the drive, voltage filtering may be required. One will have to check the noise specification on the drive circuitry against the application to see if low pass filtering is needed. To perform closed loop control, one would have to provide a feedback signal which creates the demand drive voltage for each axis. The gain of that loop will have to be determined based on the requirement for steering control. Unfortunately we do not have a write-up for doing this at the moment.

I am thinking about how best to setup the GVS002 for a step and hold app/ Is there any benefit to low pass filtering the DC voltage send to the drive circuit? Also is there any knowledge base on how to operate these closed loop? I presume one can develop a control loop based on the position error and the drive voltage ? Thanks.

Response from Tim at Thorlabs: The inputs only need a few mA to operate. For example, this DAQ card http://sine.ni.com/nips/cds/view/p/lang/en/nid/203224 has two outputs at 2mA or 4mA. This should be sufficient to operate the driver boards. Also, we can offer the GVS012 with gold mirrors as a special.

Response from Javier at Thorlabs to Mathieu: Thank you very much for contacting us. It is certainly possible to fix the position of the scanning galvo mirrors by applying a DC voltage. For example, the GVS001 1D mirror has an angular translation of ±12.5°, with 0.8 V/deg scaling. For 5° translation, you would apply 4 VDC, and if you wanted the galvo to stay at that position, you would continuously apply this voltage. This principle makes the galvo mirrors very useful for steering, scaling, and aligning laser beams. I will contact you directly fir further assistance.

Response from Javier at Thorlabs to magnasco: Thank you for contacting us with your question. You are correct, the full angle deflection of ±12.5° and resolution of 0.0008 ° (15 µrad) gives addressability to 31250 points. Note this is with the GPS011 power supply, only. With a standard switch mode power supply unit this drops to ~6250 points.

Response from Javier at Thorlabs to song31037: The material of the main body of the large galvo mirror systems is aluminum. I will get back to you with information on the exact type.

A response from Oli at Thorlabs to Liam: We can supply the galvo with mirrors for this wavelength as a special. However, unfortunately, if you already have a system with fixed (glued on) mirrors we cannot retrofit these at a later date. With the new galvo systems that have removable mirrors this could be retrofitted. I will email you directly with the specs and details. Many Regards, Oli

Response from Javier at Thorlabs to jripoll: Thank you for your feedback. We currently do not provide software/drivers for our galvo mirror systems. They are controlled through analog input, so it is relatively easy to develop an software application through LabVIEW or LabWindows/CVI, for example. You can then use a data acquisition card to provide the interface. We may be able to provide some examples that you can model your application after. I will contact you directly with more details.

It is not clear how the galvo mirror is controlled. Does it come with labview compatible drivers like the T-cube? Thanks! Jorge

Response from Javier at Thorlabs to n.marty: Thank you for your feedback. We currently do not have a galvo mirror system designed for a maximum beam diameter of 30 mm. I will propose this product to our design engineers.

Your 2 axis galvo mirror system (GVS011/012) looks very interesting, however we are looking for bigger mirror size ( 30mm). Do you have this type of product? Best regards, Nicolas Marty

response from Javier at Thorlabs to alee: Yes we do. Our LSM series scan lenses are M25x0.75 threaded. We offer thread adapters such as the SM1A12 which couple this thread onto our SM1 threaded components. For example, the SM1A12 is perfectly compatible with the GCM002 cage cube adapter for the GVS002. You could then mount any of the LSM scan lenses onto the SM1A12.

does thorlabs make an adapter piece to attach their scan lenses to these scanner assemblies?

A response from Adam at Thorlabs: The Galvo scanners we provide can operate as step controlled or continuous control. The type of control is dependent upon the waveform signal generated, for example, through a DAQ card controlling the Gavlo scanner. I will email you to get more information about your application.
