Yes, I was disappointed when I received my PL520, I expected it to produce a round dot, not!
Oh I didn't know that. It would make sense.No direct diode laser gives TEM00 modes. They don't produce a Gaussian beam. Even single mode diodes have a rectangular emitter that becomes the dot when collimated.
I'll have to take another look at mine, because mine appears to have a nice round dot, but I could be wrong.Yes, I was disappointed when I received my PL520, I expected it to produce a round dot, not!
