Re: O-like 400mw green - Review
Well with my o like the actual module itself came out with no pressure force at all, i only screwed the lens housing back in and it went in to far as the module came out like a penny from a bubblegum machine lol.
So mine never made a good solid contact with the host itself , it never even became warm in the hand only after 2 minutes or more.
So i might say , check yours if the module inside comes out easy...:thanks:
Thanks for the pics! +1
You gave me the motivation to take mine apart to see if I could fix the beam.
You can see how off center the white plastic lens is in mine.
The glue is semi-hard and can be cut with an exacto knife.
Carefully removed the lens.
Thought I was a hot shot by now, so I just centered the lens, glued it on,
and fired it up.
OOPS! Lens practically blocked the beam. Turns out the whole module is not straight. You have to offset the white lens to compensate. Except O-Like didn't get mine right.
Had to mount the laser perfectly vertical in a vise and mark a spot on the ceiling with a plumb bob. The very slightest movement of the lens made a big difference in the beam angle. Put a dab of glue down and used tweezers and long toothpicks to adjust it just so. Then put another dab of glue on the other side to fix position. Here's the finished module. You can see the whole module is not centered in the host.
Oh, and here's a shot of the pot (MUST... RESIST... TURNING... POT
)
And the results?

I'm a happy camper now.
Of course, if you screw up doing this, you void your warranty.
Susie is not going to warranty these for crooked beams either.
Here's her comments (read from the bottom up):

This is the best I can get it. You can never focus it round:
The power is OK now.
