F-Theta lens
The optional F-Theta lens is specially designed for use with 2-axis deflection units. It focuses the laser
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.

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.).
NOTE
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.
