I just got my first HeNe laser and the beam diameter is approximately 10mm or 3/8'' at the aperture.
Is this normal? I baught it off of Ebay and the seller didn't have any specs in the description. I just assumed it would be around 1mm.
Don`t get me wrong. It's a great laser. I even think that it's brand new.
Also, I turned it on for about an hour, and it seemed to really heat up. I expected to get warm, but it got pretty hot.
It wasn't too hot to touch or anything but I don't want a fire hazard.
Any answers would be appreciated.
