Did I lose a piece of my laser optics?

[SomeOtherDude]

Hi, recently I bought this laser module - https://www.banggood.com/405nm-50mW...r-Generator-Diode-p-960448.html?rmmds=myorder
And I did a few modifications, like replacing the provided power supply. In the process, I unscrewed the optics and it popped out, because of the spring loading.
After reassembling, my laser cannot be focused to a dot anymore, this is the best focus that I can get - http://i.imgur.com/xhcjwkv.jpg
This is the current state of the laser optics - http://i.imgur.com/KmefCKb.jpg

Am I missing a piece of the optic assembly? Or did I just somehow destroyed the laser?

Looks like your laser might be dead there bud Kind of looks LED'd. Someone else with more experience could tell you better though

Your window looks cracked, is it?

Good job noticing that, going by the image of the dot OP provided that looks like a likely cause.

Can you give us closer up pictures of the LD window OP?

or by any chance if the diode window isnt broke try the lens backward.maybe after you remove it you placed it wrong

That looks like the bar in the window of most LDs that is part of the diode holding the emitter. I was thinking the same thing about the lens being in backwards.

Could be an image artifact, but that window at the least doesn't look clean.

I can see the mount for the LD chip too, but I don't think that's causing the window to look dirty/damaged.

There looks to be some kind of shmutz all over the module and diode. Can't tell if it is real or just the camera.

Get a pic of the other side of the lens.
