G3 Series 2D Galvo Scanner Models

The G3 Series includes three configurations: G3 Base, G3 STD and G3 ULT. Each model has a different balance of scanning speed, dynamic response, linearity and long-term stability.

G3 Base – Standard 2D Galvo Scanner

The G3 Base is designed for standard industrial laser processing applications requiring reliable beam positioning and consistent scanning performance.

With a marking speed of 5,000 mm/s, positioning speed of 10,000 mm/s and repeatability of less than 2 μrad, G3 Base provides a practical configuration for general laser marking, engraving, cutting and cleaning equipment.

It is suitable for OEM machine manufacturers seeking a balance between scanning performance, system configuration and equipment cost.

G3 STD – High-Speed 2D Galvo Scanner

The G3 STD is designed for applications requiring faster scanning and positioning performance.

Its marking speed reaches 10,000 mm/s, with a positioning speed of 16,000 mm/s. A tracking error of 0.11 ms and 1% full-scale response time of 0.26 ms support demanding dynamic scanning requirements.

The G3 STD is suitable for high-speed laser marking, rapid QR code processing, automated production equipment and applications involving frequent beam movement.

G3 ULT – High-Precision 2D Galvo Scanner

The G3 ULT is designed for applications where linearity, repeatability and long-term scanning stability are important selection criteria.

Compared with G3 Base and G3 STD, G3 ULT provides improved nonlinearity and 8-hour drift performance, with nonlinearity below 0.4% and drift below 0.1 mrad over 8 hours.

It is suitable for precision laser material processing, semiconductor processing, FPC cutting, flexible material cutting and other applications requiring consistent scanning accuracy.

G3 Base vs G3 STD vs G3 ULT: Technical Specifications

Use the following comparison to evaluate the three G3 configurations according to your processing speed, precision and stability requirements.

All three models use a 10 mm standard input aperture and XY2-100 interface. The main differences are their dynamic response, scanning speed, thermal drift and linearity.

How to Choose the Right G3 Galvo Scanner

Selecting a galvo scanner should start with the actual processing requirements rather than the maximum speed listed in a specification sheet.

1. Choose According to Marking Speed

If your equipment requires frequent beam movement and short processing cycles, compare the marking speed, positioning speed and step response time together.

The maximum marking speed does not directly represent actual production throughput. Processing results also depend on marking content, line spacing, laser parameters, material characteristics and optical configuration.

2. Choose According to Precision and Stability

For precision processing, evaluate repeatability, nonlinearity, gain drift and offset drift together.

For applications where repeatability is the primary requirement, all three models provide a published value below 2 μrad. When lower nonlinearity and improved long-term stability are more important, G3 ULT is the preferred configuration.

3. Choose According to the Processing Application

For dedicated high-power laser welding equipment, see our G3 Weld High Precision Welding Galvo Scanner.

For curved surfaces or workpieces with changing heights, evaluate the G3-3D Galvo Scanner, which adds Z-axis focus adjustment.

Dynamic Performance, Repeatability and Thermal Stability

The G3 Series provides several dynamic and precision parameters to help equipment designers evaluate scanning performance.

Dynamic Response and Scanning Speed

The marking speed and positioning speed determine different aspects of galvo movement.

• Marking Speed describes the speed of beam movement during processing.
• Positioning Speed describes the speed of movement between processing positions.
• Tracking Error evaluates the dynamic response of the scanning system.
• Step Response Time measures the response to a commanded change in position.

For high-speed applications, these parameters should be evaluated together with marking content, field size and laser processing conditions.

G3 STD provides the highest published marking speed and positioning speed in the current G3 range, making it suitable for applications with demanding scanning-cycle requirements.

Repeatability and Nonlinearity

Repeatability and nonlinearity describe different aspects of scanning accuracy.

Repeatability indicates the consistency of repeated positioning, while nonlinearity describes deviations from the expected linear scanning relationship.

The G3 Series provides repeatability below 2 μrad across all three configurations. G3 ULT further improves the published nonlinearity specification to below 0.4%.

For applications requiring more demanding precision targets, customized scanning configurations can be evaluated according to the required optical and mechanical design.

Thermal Drift and Long-Term Stability

Temperature changes can affect the positioning behavior of a galvanometer scanner during continuous operation.

The G3 Series provides gain drift, offset drift and 8-hour drift specifications for evaluating its thermal stability.

G3 ULT is the preferred option when lower long-term drift is a key requirement.

For customized projects, JCZ can also configure enhanced thermal management, cooling arrangements and performance targets according to the operating environment and application requirements.

Optical Configuration and Wavelength Compatibility

The optical configuration of a galvo scanner must match the laser source, beam diameter, mirror aperture and focusing lens.

The G3 Series supports four standard wavelength options, with additional optical configurations available for customized projects.

Laser Wavelength and Mirror Configuration

The mirror substrate and coating should be selected according to wavelength, laser power density, pulse characteristics and scanning requirements.

For example, a 355 nm UV system requires optical components designed for UV transmission and reflection, while a 1064 nm fiber laser system needs a compatible infrared optical configuration.

JCZ can configure optical components according to the selected laser source and processing requirements.

View the JCZ Laser Source Range to compare compatible laser technologies.

Input Aperture and Beam Compatibility

The standard G3 configuration uses a 10 mm input aperture. Customized scanner configurations can be supplied with different aperture sizes to accommodate different beam diameters and optical designs.

When selecting an aperture, consider:

• Laser beam diameter at the scanner entrance.
• Beam quality and beam expansion configuration.
• Mirror clear aperture.
• Laser wavelength and mirror coating.
• Required scan angle and optical field.
• Compatibility with the selected F-theta lens.

A larger aperture does not automatically produce a larger marking field. The final working field also depends on the optical design and focusing lens.

Scan Angle and Optical Design

The standard G3 Series provides a scan angle of ±0.35 rad.

Customized scan-angle configurations can be developed according to the required optical geometry, including options up to ±0.393 rad.

For OEM equipment, scan angle should be evaluated together with focal length, working distance, beam diameter and required processing field.

Mirror Displacement and Optical Customization

For projects requiring specific optical-axis positioning or mechanical integration, JCZ can customize:

• Beam displacement.
• Optical-axis height.
• Mirror dimensions.
• Mirror substrate and coating.
• Scanner housing.
• Optical entrance and exit arrangements.
• Mounting and alignment structures.

Provide the existing optical drawing or machine layout so the scanner configuration can be evaluated against the complete beam path.

F-theta Lens Matching and Working Field Selection

The galvo scanner and F-theta lens form an integrated optical system. Selecting a scanner without considering the lens may result in an unsuitable beam diameter, working distance, scan field or spot size.

JCZ provides both flat-field and telecentric F-theta lens configurations for different industrial laser processing requirements.

JCZ’s flat-field F-theta lens range covers UV to IR wavelength configurations, with focal lengths from 63 mm to 1450 mm.

View the available options:

• Flat-Field F-theta Lens
• Telecentric F-theta Lens

Information Required for Lens Matching

For example, a larger scan field generally requires a different focal length and optical design. The resulting spot size and working distance must also be considered.

Send your optical parameters to JCZ for a matched scanner and lens configuration rather than selecting the lens by focal length alone.

Electrical Interface and Controller Compatibility

The G3 Series uses the XY2-100 interface as its standard communication configuration.

For customized equipment, alternative communication and control configurations are also available according to the selected scanner and controller architecture.

Matching the Galvo Scanner with a Laser Controller

A compatible controller is essential for coordinating the laser source, scanner movement, processing data and external machine signals.

For EZCAD3-based systems, the DLC2-V4 Laser Controller supports mainstream laser types and galvo control protocols, including XY2-100 and other supported interfaces.

For compatible EZCAD2-based systems, the LMCPCIE Laser Controller provides PCIe-based laser and digital galvo control.

For large-format continuous laser processing requiring coordination between the galvanometer and motion platform, the ZEUS Intelligent-Continuous Laser Processing Controller is another system-level option.

Before ordering, confirm the following:

1. Galvo scanner model and communication protocol.
2. Controller model and firmware configuration.
3. Laser source interface and control requirements.
4. Required motion axes and encoder feedback.
5. Electrical connections and I/O requirements.
6. Software and calibration configuration.

The controller should be selected according to the complete machine architecture, not solely according to the scanner interface.

Mechanical Design, Cooling and Environmental Customization

For OEM equipment manufacturers, mechanical compatibility is as important as optical performance.

The standard G3 models have different weights and electrical requirements. Additional mechanical and thermal configurations can be customized for machine integration.

Customized mechanical configurations can include:

• Scanner housing dimensions.
• Mounting hole positions.
• Optical entrance and exit positions.
• Connector direction.
• Beam displacement.
• Cooling connections.
• Cable routing and installation space.

For projects requiring water cooling or air flushing, the cooling arrangement should be defined together with the mirror configuration, laser power and operating environment.

Provide a mechanical drawing or available installation space when requesting an OEM configuration.
