3.2.2 F-Theta lens
The optional F-Theta lens is specially designed for use with 2-axis deflection units. It focuses the laser
Optional
beam at maximum quality on any position in the processing area. At the same time, it partially optically
compensates for the barrel-shaped distortion that is unavoidably produced by 2-axis deflection units.
The remaining distortion (see figure) must be compensated by the deflection unit.

3.2.3 Connections
The MINISCAN II has the following connections:
 to a laser system (mechanical and optical)
 to a focusing unit (e.g. F-Theta lens)
The power supply and control use the analogue or digital interface depending on the product version
(see page 19 ff.).
 Controlled deflection is only possible if the specified power supply is connected. In addition
proper control using the specified control commands must be guaranteed at all times.
