Hi I have just installed a new lens and I am cutting much better

Hi I have just installed a new lens and I am cutting much better now but I see a small 3/4mm faded circle to the side of the beam on the material. Is this normal or is it because my beam isn’t fully aligned, thanks. The second faded circle isn’t a 2nd cut line like you sometimes get.

A reflection in the air assist nozzle?

Not normal. Don has a good suggestion. Definitely check your beam alignment. If that doesn’t fix it then it’s likely a flaw in the lens.

Do you have air assist and what kind of nozzle?

I don’t have an air assist, The alignment seems to be fine, the beam falls in the centre of the mirror in most places. It’s a brand new lens. Shall alter alignment and see it it changes or disapears. Don’t think it is a shadow from anything. Thanks
