We have a 4000w hankwng and we are trying to do engraving on stainless. the quality is not good.
We are using a 5" focal lens do you think a smaller focal length will help in a better quality.like a 3.75" focal lens?
any tips please?
We have tried various vendors but Ophir and IIVI are the ones you need to go with.
we use the black magic lens on our trumpf lasers and they have lasted longer than the standard lens.they are a bit cheaper in price than the II-VI MP5 and ophir's clear magic.
you will not see a difference between...
