PRODUCT OVERVIEW
MOVIA scan heads are used as part of a galvanometer-based laser system and
steer optical beams on a XY image field (2D) for all possible laser applications. See

PRINCIPLES OF OPERATION
In a MOVIA scan head, two galvanometers scanners with mirrors synchronize and
rotate to steer the laser beam across the XY field.
The beam enters the scan head through the input aperture and encounters the
X mirror. The mirror-galvo pair is responsible for deflecting the beam, as directed,
along the X axis of the scanning field. The laser beam then encounters the
Y mirror, which deflects the beam along the Y axis.
With the use of a controller like Cambridge Technology’s ScanMaster Controller,
you can accurately steer the laser beam anywhere within the usable field. See
Figure 2.
