Introduction
This manual covers the installation and use of
Thorlabs’ QS15 & QS20 Series 1- & 2-Axis Galvanometer Scanners.
These galvo scanners are specifically designed to rotate optical scanning mirrors at a high bandwidth and then
settle to a high degree of accuracy and repeatability. They are designed to carry a balanced inertial load, matched
to the size of the stator and rotor combination. The exact inertia that can be driven depends on the application,
which in turn specifies a speed and settling accuracy requirement.
WARNING
Safety precautions should be taken to avoid exposure to laser radiation. During system shutdown or
malfunction, the scanner can point the beam anywhere within its range of rotation. It is up to the user
of these scanners to limit the exit aperture of the laser beam in order to provide laser safety.
CAUTION
This manual contains all the information necessary to install and operate the the galvo scanner. Servo
drivers are factory tuned with a matched galvanometer and mirror. Do not adjust the servo driver in
the field. Only factory trained service technicians should adjust any of the potentiometers on the
board. If it becomes necessary to return a servo driver board to the factory, the matching
galvanometer and mirror should be returned along with it. Any unauthorized attempt to adjust the
servo by an untrained individual could result in serious damage to the scanner, mirror, and
electronics.
CAUTION
Galvanometer bearings are delicate and prone to damage if not handled with care. Never apply
excessive axial or radial force to the galvanometer rotor. Dropping the galvanometer could damage
the mirror, rotor, bearings, or position detector.
