RAYLASE SUPERSCAN IIE

RAYLASE SUPERSCAN IIE is a two-axis galvanometer-based scanner system developed for demanding industrial laser applications where high dynamics, precision and low drift are important.

The scanner system is available with several apertures and can be configured for different laser wavelengths, power levels, optical systems and working fields. SUPERSCAN IIE is suitable for applications including laser marking, laser ablation, laser welding and other fast and precise laser processes.

LMI AB supplies RAYLASE SUPERSCAN IIE and can assist with the selection of scanner configuration, optics, control and integration into industrial laser systems.

Designed for high precision and stability

SUPERSCAN IIE is designed for applications where scanner accuracy and long-term stability are important to the process result.

RAYLASE uses a twin-shell design to minimise thermal drift. For applications with even higher stability requirements, an Enhanced version is also available, which according to RAYLASE provides approximately 50% improved long-term drift performance.

Long-term drift can be reduced further by using water-based temperature control, which can be particularly valuable in precision applications or under varying thermal loads.

Applications

RAYLASE specifies SUPERSCAN IIE for a wide range of industrial laser processes, including:

laser marking
laser engraving
laser ablation
laser welding
cutting
perforation
micromachining
processing-on-the-fly
ITO structuring
Ag patterning

The appropriate configuration depends on factors including laser wavelength, laser power, beam diameter, aperture, mirror substrate, optics and required working field.

Several apertures for different applications

SUPERSCAN IIE is available in several versions with different input apertures. This makes it possible to adapt the scanner system to different beam diameters, laser sources and optical requirements.

Available apertures include, depending on version:

7 mm
10 mm
15 mm
20 mm
30 mm

RAYLASE also offers special versions, such as SUPERSCAN IIE-20 L, for specific mechanical and optical configurations.

Galvo mirrors and wavelengths

SUPERSCAN IIE can be configured with different mirror substrates and optical coatings depending on laser wavelength and application.

RAYLASE offers configurations for a wide range of common laser wavelengths, including UV, green laser wavelengths, fiber and YAG wavelengths as well as CO₂ lasers.

Depending on version, mirror substrates such as fused silica or silicon may be used. The choice influences factors including dynamics, thermal properties and the optical load that the scanner system can handle.

High dynamics and fast beam positioning

The galvanometer-based design enables the laser beam to be positioned very rapidly across the working field.

Dynamic performance varies between different apertures and mirror configurations. Smaller apertures generally result in lower moving mass and therefore higher acceleration and scan speed, while larger apertures make it possible to handle larger beam diameters and more demanding optical requirements.

For the SUPERSCAN IIE-20, for example, RAYLASE specifies typical processing and positioning speeds of up to 35 rad/s depending on mirror configuration.

Thermal stability and drift

Thermal drift is an important parameter in scanner systems because changes in temperature can affect the position of the laser beam over time.

RAYLASE specifies values for SUPERSCAN IIE including:

maximum gain drift < 15 ppm/K
maximum offset drift < 10 µrad/K
repeatability 2 µrad RMS
long-term drift over 8 hours < 150 µrad
long-term drift with water-based temperature control < 100 µrad

For particularly demanding precision applications, the Enhanced version and water-based temperature control can be used to further improve stability.

Control and interface

SUPERSCAN IIE uses digital control and is compatible with the XY2-100 protocol.

The scanner can be controlled using, for example, RAYLASE control boards and integrated with the laser source, optics and machine control as part of a complete industrial laser system.

Depending on the application, system integration may also include laser triggering, digital I/O, encoder signals, processing-on-the-fly, vision systems and other automation.

SUPERSCAN IIE-20

The 20 mm version is particularly interesting for many industrial fiber and YAG laser applications where a larger beam diameter needs to be combined with high dynamics.

For SUPERSCAN IIE-20, RAYLASE specifies a weight of approximately 3.3 kg without objective and a beam offset of approximately 26 mm, depending on mirror substrate.

The 20 mm version is available with both fused silica and silicon mirror configurations. Processing and positioning speeds of up to 35 rad/s are specified for these versions.

For high-power applications

SUPERSCAN IIE is designed to support configurations for high laser powers. However, the permissible power depends on the complete combination of laser wavelength, beam diameter, mirror substrate, coating, cooling and laser process.

The scanner system should therefore not be selected solely based on aperture or basic model designation. The complete optical and thermal configuration must be matched to the application.

Water-based temperature control and air purge

For applications with demanding thermal stability requirements, SUPERSCAN IIE can be equipped with water-based temperature control for the electronics and galvanometers.

RAYLASE also offers air purge for certain configurations. This helps maintain stable operating conditions and can be particularly relevant at high laser powers and in demanding industrial environments.

Replacing an existing SUPERSCAN IIE

SUPERSCAN IIE is available in many different versions, and units with the same basic model name may differ in areas such as:

aperture
mirror substrate
optical coating
mechanical configuration
connections
cooling and temperature control
optical configuration

When replacing an existing scanner, the part number, serial number and complete configuration should therefore be checked.

Photographs of the unit and its identification plate, together with information about the laser source and application, can help identify the correct version. LMI AB can assist in identifying the existing configuration and specifying a suitable replacement.
