So I was using my dual power 40mW/180mW laser today and I was setting the focus to burn some stuff. I like to set the focus with the low power so I don't have to worry about overheating. I was using a black piece of rubber about 3" away from the lens so I could see the dot well.
When I got the dot down to little pin-prick of light it started smoking the rubber @ only 40mW.
Just to see the differnece... I hit the high power button and boy did it start burning & smoking the rubber.
Is it normal that a well focused 30-40mW 405 beam can smoke soft rubber?
Maybe I'm pushing more than 40mW on the low setting?? (unlikely @ 65mA with Aixiz glass)
