2 6 lens
2 6 lens
(OP)
I have recently switched to 2-6 focusing lenses due to cost. The first lens was troublesome to begin with. The second ran great until it got dirty. The third was good for two days, then suddenly it started acting up. No spots or apparent stress, put back in old dirty lens and it out preformed the new clean lens. Has anyone experienced this from 2-6 before? By the way, the lens case said it wasn't made in the U.S.

We have been using II-VI lenses for years. They last months.
We have received optics from Amada that say II-VI on them.
It is my understanding that II-VI supplies Amada all of their optics.

You mentioned on your post that you checked the lens for stress. Did you check this with a couple of polarizing lenses? Can you also define the lens getting dirty?
I find it hard to believe you are having trouble with these lenses because they are the best in the industry.

Are the lenses you talk about 5" FL or 7.5"? If you are using 5.0" FL on thin material, are you going shutterless or pierce on the fly? What are you cutting that is causing a lot of spatter on the lens? Stainless? Aluminum? SS with PVC (Laser Film)?
