FUNCTIONAL DESCRIPTION
4.1
Laser beam deflection unit
The deflection unit can be used to deflect a laser beam in X and Y directions. This produces
an area within which a laser can be directed at any position. This area is known as the "mark-
ing field" and is shown in Fig. 2. Deflection is performed by two mirrors, each of which is
moved by a galvanometer scanner. The deflection unit has a beam input, into which the laser
beam is fed, and a beam output, through which the laser beam is emitted from the unit after
deflection. Only suitable lasers can be fed into the beam input. Refer to the corresponding
data sheet in the Appendix for details. Depending on the version, the beam output is either
open or fitted with an F-Theta lens or glass guard (
