dynAXIS 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. The primary area of application is the fast and precise positioning of mirrors for the deflection of laser beams.
®
The exceptional dynamics of SCANLAB’s dynAXIS scanners are
the result of 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
deflection mirror´s inertial load. 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 (except
dynAXIS ® XS and dynAXIS ® T). This allows temperature stabilization for further enhancing long-term stability, even under fluctuating ambient conditions.
The new scanners of the dynAXIS ® 3 series feature a revised position detector for exceptionally low drift, highest linearity and,
optionally, extended deflection angles.
For all dynAXIS ® scanners, SCANLAB provides suitable mirrors and
mirror coatings for all common laser wavelengths and power levels.
In addition to excellent reflection properties, the mirrors are also
optimized with respect to inertial load, stiffness and flatness.
The high quality of SCANLAB’s galvanometer scanners enables errorfree operation in long-term and continuous use. Comprehensive
measurements on custom test benches assure that the highest level
of quality is continuously maintained.
