Hi guys! I new to the world of laser etching. My company bought a ULS 40 watt C02 last year and i've been the guy running it. It's awesome!! :D:D:D My question is laser lens sizes. We have a 2.0. I know there are other sizes but what's the difference? I come from a photography background and know about Depth of Field and from what I gather the lens number has something to do with how much "in focus area" the lens has. We do a lot of vinyl (no PVC) so our 2.0 is fine for a flat surface, but we're getting into mugs and pens,etc. On some items I have to do two passes and move the table up or down to get a proper etch. We don't have a rotary attachment. So, wouldn't a 4.0 lens give me more focus area and eliminate the need for doing another pass?
Thanks,
