F-Theta Scan Lens - Achromatic

 

When a vision system is being integrated into the laser machining system, our achromatic F-Theta scan lenses are colour-corrected between working wavelength and vision wavelength. They can provide accurate vision positioning function and it is very useful for online inspection systems where the operator does not need to have offline inspection on the work piece.

Remark: The spot size is simulation result, it does not reflect the actual spot size on workpiece as the simulation does not consider the material properties and how the laser being absorbed during machining.
