Default My laserpointer doesn't make a DOT, but a strange wave, who can help me?

As my title sais, my laserpointer have to make a dot, but it isn't a dot at all. i think it is a 650nm red laser with visible beam. I have added a picture of my strange problem.

What laser host is it? (do you have a picture?) Is the lens the correct way round?

Can you take the lens off and show us the raw output of the red laser ?

That is just an Aixiz acrylic lens. There are notches in the black barrel. Can you unscrew it ? Only if the barrel isn't glued to the host.
The dot looks like the laser beam isn't hitting the lens straight but at an angle.

As Blord said, can you show us a picture of the laser pointed to a wall without the lens on.

By the way, between laser en lens there was also a spring.

The raw output looks very good. It is perfect centered.
I think you have a crooked lens. Do you have another lens ?

Yeah I would say that the little black lens inside is squint. Try unscrewing it and putting it back in.

spring won't have anything to do with it i don't think.

It has something to do with the actual lens. Look in the lens housing and see if the lens is laying straight or if it's crooked.
