dynAXIS ® XS, dynAXIS ® S, dynAXIS ® M, dynAXIS ® L

system components for integratorssystem components for integratorsdynAXIS ® galvanometer scanners are high-performance rotary motors for optical applications. They consist of a motor section based on moving magnet technology and a high-precision position detector (PD).

The primary area of application is the fast and precise positioning of mir-rors for the deflection of laser beams.

The exceptional dynamics of SCANLAB’s dynAXIS ® scanners are the result of more than twelve years of experience in developing and manufacturing scanners, scan systems and scan solutions for industrial use.

The motor section of each dynAXIS ® is ideally matched to the inertial load presented by the mirror. The optimized rotor design is largely responsible for the favorable dynamic properties and resonance characteristics. Axially pre-loaded precision ball bearings guarantee a backlash-free rotor assembly with high stiffness and low friction. Special attention has been paid to long bearing lifetimes.

The optical position detector system is characterized by high resolution, as well as good repeatability and drift values. The scanners are equipped with heaters and temperature sensors (optional for dynAXIS ® XS). This allows temperature stabilization for further enhancing long-term stability, even under fluctuating ambient conditions.

SCANLAB provides all dynAXIS ® scanners with suitable mirrors and mirror coatings for all typical laser wavelengths. In addition to very good reflec-tion properties, the mirrors are also optimized with respect to inertial load, stiffness and flatness.

The high quality of SCANLAB’s galvanometer scanners enables error-free operation in long-term and continuous use. Comprehensive measurements on custom test benches assure that the highest level of quality is continu-ously maintained.

dynAXIS ® XS dynAXIS ® S dynAXIS ® MdynAXIS ® L

Mounting

The rotationally symmetrical flange facilitates mounting. The scanner hous-ing must be electrically insulated from the machine structure. Mirror stops are already integrated in the scanners. The mirror is directly bonded to the scanner’s shaft; the mirrors of the dynAXIS ® M and dynAXIS ® L are attached via a mir-ror mount to the shaft.

intelliSCAN ® 10

smart scanningThe intelliSCAN® 10 scan head is the first member of a new, digitally con-trolled generation of scan heads.

Newly developed digital servo amplifiers control the industry-proven dynAXIS® S galvanometer scanners. Employing a high-performance control algorithm, these digital servos enable improved dynamics and marking quality as well as extensive possibilities for diagnosis and for communica-tion between the scan system and the customer‘s control computer.

The intelliSCAN® allows real-time monitoring of all important scan system operational states such as mirror positions and speeds, drive currents, sup-ply voltage and temperature. As a result, processing operations can be monitored, protocolled and modified if required – these abilities are espe-cially welcome in safety-critical applications.

The intelliSCAN® creates new remote-diagnosis possibilities. It has the necessary facilities to support software-querying from any location to de-termine accumulated operating hours, serial number, date-of-manufacture and essential operational states. Thus, deviations can be quickly detected and corrected.

The product‘s electronics architecture also enables functionality extensions via firmware modification, such as the planned ability to change scan head dynamics during processing and thereby optimally adapt the scan head to particular task requirements.

maximum-power laser scanningpowerSCANThe scan systems of the powerSCAN series enable positioning multiple kilowatts of laser power onto a workpiece in just a few milliseconds. In combination with a varioSCAN, the laser beam can be dynamically focused within working volumes, thusallowing non-flat workpieces to be processed.

Apertures up to 70 mm allow small spot sizes and therefore high power densities even with large working distances. The XY mirrors and the varioSCAN‘s optics are air cooled, while the scanners, electronics and varioSCAN are water cooled. This ensures reliable operation with excellent long-term stability – even under challenging environmental conditions and with high laser powers.

Each axis of powerSCAN 50 and powerSCAN 70 is individually implemented as a sealed submodule – a calibrated and tuned unit containing a galvanometer scanner with a mirror and the scanner’s driver electronics. Thus, rapid exchangability ofindividual axes is ensured. Located in a separate sealed base module, the modularly-designed main electronics providefunctions such as a digital interface and the power manage-ment system with comprehensive monitoring functions.

new dimensions – optics in motionvarioSCAN, varioSCANFLEX

varioSCAN dynamic focusing devices enable the laser focus to be moved quickly and precisely along the optical axis. This is achieved via an optical element driven by a high-performance, tilt-free linear motor.

In XY scan systems, the varioSCAN can replace costly flat field objectives. The varioSCAN is an exceptionally ideal solution in applications for which standard flat field objectives are unavailable. The varioSCAN can also extend XY scan systems into 3D beam deflection systems. The laser focus is guided along the contour of the workpiece being processed, thus enabling processing in three dimensions. The varioSCANFLEX additionally allows continuously adjusting the image field size and working distance.

Controlling both an XY scan unit and the varioSCAN is easily achieved via SCANLAB’s RTC® interface boards.

SCANLAB offers optical configurations for a wide variety of working distances, image field sizes, beam diameters, wave-lengths and laser powers. For fiber-coupled lasers, SCANLAB offers the varioSCAN FC (see special data sheet).

varioSCAN 20

XY scan systems with apertures up to 20 mm can be extended by the varioSCAN 20 into a 3-axis scan system. The varioSCAN 20 features exceptionally dynamic performance.

Optics are available for laser wavelengths up to 266 nm. For high-laser-power applications, the varioSCAN 20 can be equipped with a water-cooled entrance aperture.

How It Works

The varioSCAN is an opto-mechanical system. Relative to a fixed-position focusing lens, a diverging lens is moved along the optical axis by a tilt-free linear motor (see illustration). This changes the overall system’s focal length. Laser beams of two kilowatts (CO2) or four kilowatts average power (YAG) can be focused.

2D Applications

In an XY scan system, the varioSCAN replaces a flat field objective. During the scan process, the focal length is dynami-cally readjusted in synchronisation with the mirror movement to maintain the laser focus within a flat image field.

3D Applications

A 3-axis system – consisting of a varioSCAN, an XY scan unit and an RTC® interface board – enables processing of non-flat workpieces. The position of the laser focus can be adapted to the contours of the part being processed. Particularly for short focal lengths, the 3-axis scan system can be combined with a flat field objective to achieve the smallest possible spot size and a large focus range in Z direction.

maximum-power laser scanningvarioSCAN FCThe varioSCAN FC is a new type of dynamic focusing unit that can be combined with a powerSCAN to realize a 3D beam deflection system for fiber-coupled multi-kilowatt lasers.

Beam delivery is based on a variable collimator, with optical elements driven by the linAXIS linear axis from SCANLAB. The laser focus can thus be moved quickly and precisely along the optical axis. The beam focus is optimized to remain a virtually constant focus diameter throughout the entire working volume.

Adaptation to various fiber connector types and numerical apertures is possible.

The varioSCAN FC is designed to handle a laser power of up to five kilowatts. To ensure reliable operation also with very high laser powers, the varioSCAN FC is equipped for water cooling.

The varioSCAN FC‘s dynamics and optical layout are designed for use with SCANLAB‘s powerSCAN systems. Both, the varioSCAN FC and the powerSCAN are easily controlled with SCANLAB’s RTC® PC interface boards.

Typical Applications:

Remote welding

Laser materials processing: welding, soldering,surface treatment (hardening, texturing ...)

Rapid manufacturing

3D applications


varioSCAN FC

How it works

The varioSCAN FC is an opto-mechanical system consisting of a variable collimator, a beam expander and focusing optics.

The variable collimator‘s optics is dynamically driven along the optical axis by the linAXIS linear axis. This allows the laser beam‘s divergence, and thus the overall system‘s focal length, to be varied.

In addition, there are provisions for manual adjustment of the nominal working distance.

Two deflection mirrors fold the beam path to keep the total system dimensions of the powerSCAN and varioSCAN FC as compact as possible.

SCANLAB offers a variety of optical configurations for adapting the system to the customer’s particular application. Working distance and field size can be adjusted by the selection of focusing optics. By exchanging the fiber adapter or collimator optics the varioSCAN FC can be adapted to various laser types.

Control

In a 3-axis system, the servo amplifier boards of the varioSCAN and the XY scan system are linked with a SCANLAB RTC ® PC interface board by a common digital interface. The RTC ®’s processor performs vital steps such as micro-vectorization, coordinate transfor-mations and image field correction.

Applications

In 2D applications, the varioSCAN – as a dynamic focusing unit – replaces a flat field objective. During the scan process, the focal length is dynamically readjusted to maintain the laser focus within a flat image field.

In 3D applications, the varioSCAN enables processing of non-flat work-pieces. The position of the laser focus can be adapted to the contours of the part being processed.

control and versatilitySCANLAB’s RTC® PC interface boards provide synchronous, interference-resistant control of scan systems and lasers in real time.

A high-performance signal processor and the supplied DLL simplify pro-gramming under Windows. Alternatively, industry-proven software pack-ages from various third-party vendors are also available for handling a palette of standard applications.

Software instructions are loaded alternately in the RTC®’s two list buffers, processed by the DSP, and output as 16-bit control signals every 10 µs to the scan system. The RTC®’s processor automatically performs vital steps such as micro-vectorization and image field correction. Laser control is synchronized with the scanner movements. Various programmable laser signals are available for vector and bitmap processing (see diagram on reverse side).

The RTC®4 is downward-compatible with the RTC®3. Additionally, the RTC®4 is capable of communicating with the processors onboard SCAN-LAB’s new intelliSCAN ® scan heads – thus, it furnishes to the control PC the real-time stream of scan head axis status parameters and enables extensive scan system diagnosis possibilities. Optimized intelliSCAN ® scan head tuning profiles for diverse processing tasks can be selected via soft-ware commands. Compared to the RTC®3, the RTC®4 offers more memory, faster performance and additional software instructions (e.g. arc com-mand). For controlling external components, the RTC®4 provides 16 digital input ports and 16 digital output ports.

SCANLAB’s RTC® PC interface boards are available with numerous options, providing the extensive flexibility system integrators need for meeting di-verse customer requirements. Furthermore, an I/O extension board is avail-able for controlling additional external components.

independent control RTC® SCANaloneSCANLAB’s RTC® SCANalone Board enables real-time control of scan systems and lasers without requiring a PC. The board’s high-performance signal processor and extensive internal memory make this possible. The only item required for operation is an external power supply.

Marking data can be loaded via a removable MMC memory card or by using the built-in USB 1.1 interface. The board’s internal memory can accommodate up to one million list commands – a capacity that meets the needs of both today’s and tomorrow’s complex applications.

External control signals can be used to start or otherwise influence the execution of applications loaded in memory. For this purpose, the board is equipped with an additional 16-bit digital input and 16-bit digital output.

Control commands to the scan system are issued synchronously every 10 µs as 16-bit digital output signals.

The RTC® SCANalone can also be operated via a PC connected to the board’s USB interface. In this mode, the RTC® SCANalone offers the same functionality as an RTC®4 PC interface board.

The RTC® SCANalone software interface and hardware connection capabilities are largely compatible with those of the RTC®4 PC interface board. All options offered for the RTC®4 PC interface board (e.g. 3D or processing on the fly) are also available for the RTC® SCANalone.
