Achromatic Telecentric Scan Lens

 

When a vision system is being integrated into laser machining system, our achromatic telecentric scan lenses are colour-corrected between working wavelength and vision wavelength. the achromatic telecentric scan lens offers the benefits as same as the normal telecentric lens yet able to provide accurate vision positioning function. 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.
