These Two-Axis Galvo Scan Heads provide two-dimensional scanning in a variety of laser applications. Each scan head consists of a dual-axis galvo motor and mirror assembly, two servo amplifiers, and communication electronics. The moving-magnet galvanometers deliver high speed and accuracy while integrated optical position detectors ensure precise control, high linearity, and low drift. The scan head housings are compact and include industry-standard mechanical interfaces for integration into a system.

The DCB Series Scan Heads are designed for OEM integration or easy plug-and-play operation. The system includes advanced digital signal processing (DSP) to rapidly compute and predict the exact drive impulses required to achieve small mirror movements with the fastest possible acceleration. The unit features self-tuning technology that automatically compensates for mechanical wear, extending its lifetime and eliminating issues associated with traditional analog servo filters. A detailed self-diagnosis and system check determine the operating parameters of the individual galvos, ensuring high accuracy and precise, error-free laser marking positioning.

System Control
These scan heads are configured to accept inputs via the XY2-100 communication protocol. This industry-standard digital interface integrates with PC-based hardware and software packages for laser marking and micromachining. We recommend the SAMLight software package from SCAPS; click here for information on this software. Analog input versions are also available. Power supplies and cables are sold separately.

Scan Lenses and Lens Ring Kits
A scan lens and lens ring are required in order to use a scan head. The XG series scan heads require both a scan lens and lens ring kit to be purchased separately; DCB series scan heads include a lens ring kit but require a scan lens separately. See the Scan Lenses and Rings tab to choose an appropriate scan lens and lens ring for your galvo scan head.

I ordered XG210 with GPWR15 power supply. "Specifications and application data" of GPWR15 is the only technical document I received and it is lacking of the following information: 1) Should earth ground be connected to the housing of the power supply? Should the housing be afterwards connected to somewhere else? 2) Where exactly I have to connect +15 V, -15 V and GND cables of the power cable of the XG scanner head? Probably to the pins +OUT, -OUT and COM? 3) Probably -OUT pin must be directly connected to the -S, and +OUT to the +S? 4) Do I need to integrate an electrical fuse?

Thank you for contacting us here at Thorlabs with your inquiries. Regarding your inquiries, I have reached out to you directly to complete the setup and troubleshooting of your galvo system.

Hello, We bought a galvo scan head ( DCB210-Y1HP) and some accessories from Thorlabs but we can not find a suitable angle bracket to connect the galvo scan head to other optomechanical parts. The 4xM5 design on the scan head is not popular. Why aren't they M4 or M6? Their distances are also not familiar with Thorlabs' design (54x15 mm). Another thing is no support documents such as drawings, 3d files for the lens SL16385-Y1 and it group.

Need a wiring diagram for the DB-25 connectorn the galvo head. We are providing our own controller to drive the galvo, but we do not know how to wire to this connector.!!

All 2-axis galvo scan heads above require a scan lens for proper operation. These scan lenses are suitable for scan head item #s that start with XG. For scan lenses compatible with DCB series scan heads, see below.

Scan lenses produce a flat image plane and a spot size that suffers minimal distortion as the angle of the incident beam with respect to the optical axis of the lens is varied; varying the angle of incidence causes the focal spot to scan over the field of view in the image plane.

Each table includes scan lenses that are compatible with a particular galvo scan head model. After selecting a scan lens, see below to choose an appropriate lens ring for mounting the scan lens to the galvo scan head.
