4.1
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 for details. Depending on the version, the beam output is either open or fitted with
an F-Theta lens or protection glass ( page 15, F-Theta lens).
