Default My dot is surrounded by other very small dot and light, is that normal ?

Hi

My dot is surrounded by other very small dot and light
The raw output looks normal but it has a few black holes in it and has like () around it

Edit: 9mm diode, 9mm stick lens

This the smallest I could get, and it surrounded by unfocused light.

More information is useful. What laser diode ? Lens ? Picture of the "problem".

How did you put the lens in ? The flat side must be towards the diode and the round side to the front.

I know thats what I did, I even turned around many time to make sure
Is my raw output normal ?

The raw output looks good. You have a dirty diode window.

What lens barrel are you using ? Some barrels aren't deep enough to get the lens close to the diode in order to focus.

Is there anything I can do to my dirty window ? and does its effect the power by how much ?

I am using the one DTR's sells
But its deep enough, because it get very focused then less focused when I get near the diode.
