Features

Packaged Two-Axis Galvo Scan Heads

Protected Silver, Nd:YAG, or CO₂ Mirrors Available
Operate via XY2-100 Digital Signal Input
Compact Housing

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.

High Scanning Speed
Rapid Drive Impulse Computation
Easy OEM Integration or Plug-and-Play Operation
Automatic Tuning Checks When Powered On
Compatible with Analog Scan Heads Using XY2-100 Protocol
Reduced Temperature Drift

These 2-axis scan heads feature digital signal processing for high-performance scanning. The system rapidly computes drive impulses to achieve small mirror movements with the fastest possible acceleration. The unit automatically performs a self-tuning check when powered on, which analyzes and compensates for mechanical wear in the components, thereby extending the unit's effective lifetime and eliminating issues associated with traditional analog servo filters.

The housing includes an attached mount for a scan lens. The scan lens must be purchased separately to use these scan heads. See below for scan lens options.

The compatible power supply (item # GPWR24) and cable set (item # CBLA16F) are sold separately.

SL42085X-Y1	1064 nm	420 mm	Ø411.0 mm	494 mm

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.
