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". The
single pivot-point galvanometer scanner directs the beam so that the pivot point for the X direction
is at the same point in space as the pivot point for the Y direction. This is accomplished by rotating 3
turning 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.

The AGV-SPO control connections consist of three 300 mm cables terminated in 25-pin D-style
connectors. These cables can be oriented in any direction and terminated on the machine to ensure
there is no interference with beam delivery.
