Hi all,
we are making one head laser die cutting machine, sample machine is 300w combined laser tube(3 pcs 120w laser tube combined together). Now we want to make 400w (3pcs 150w laser tube combined). But for 300w machine, we tried many times for different focus lens, say F120, F100, F70, but seemed cutting result is not perfect, for whole 18mm thick board 110*90cm, about 5-7 section is not cut through. The image is for cigaret box, very complicated, say picture atttached.

So any one knows better about the right focus lens?
