Option FlatLense (USC only)
Previous pageReturn to chapter overviewNext page

This option enables the Z data channel of the XY2-100 Interface of the USC card. It is required to control 3 axis scan heads. Even if this is an hardware option, it can be enabled by the FlatLense license for every USC card.

Flat surface marking without F-Theta lens: If the 3 axis scan head is used for marking on flat parts, the third scanner axis is used instead of a F-Theta objective to keep the laser focus constant on a plane surface, the option FlatLense is required and a 3D correction file has to be used which also contains Z bit values for every correction point.

Defocus: If you have a USC card with the option FlatLense (3D UCF correction file, no Optic3D) the software has no factor to calculate mm to bit. That is why the unit of pen defocus is [216 bit / field size] instead of defined unit in SAMLight.

Real 3D vectors marking: If the 3 axis scan head is used for marking on curved parts (real 3D vectors), both options FlatLense and Optic3D are required.

note

If an RTC card is installed Real 3D vectors marking is being enabled with the 3D option on the card and the Optic3D option.
