Chapter 1: Overview
A 2-axis galvanometer scanner is used to deflect a laser beam in the X and Y directions. The laser can
be directed to any position within the two-dimensional area, which is called the “marking field”.
Deflection of the laser beam is accomplished by two mirrors, each of which is actuated by a galvano
motor. Every scan head includes a beam entrance aperture, into which the laser beam is fed, and a
beam exit aperture, through which the laser beam is emitted from the unit after deflection. Only
suitable lasers of the appropriate wavelength, power level, beam diameter, etc., may be fed into the
beam entrance aperture. Contact the factory for mirror and coating details. Depending on the
options selected for the particular scan head, the beam exit aperture may be either open or fitted
with a focal lens.

Functional Principle of a 2-Axis Galvanometer Scanner
The AGV-HP(O) control connections are two 25-pin D-style connectors. The scanner cables can be
oriented in any direction and terminated on the machine to ensure there is no interference with
beam delivery. The AGV-HPO is also available with right-side and left-side input apertures for “mirror
image” machine builds or side-by-side scanner mounting with a single laser beam split to source
both scanners.
