Help me determine if this laser module still works

This should be very simple I need to know if this laser module still works. I have a power supply. What I'm wary of doing is disassembling the module itself. For one there could be a alignment issues and there are too many unknowns.



I need to know how I can get to the electrical contact points in the module. I'm guessing I need to the remove the screws there (top picture there are 4 of them)? Either that or remove the epoxy (I think that was used to for alignment) which is why I ask.

I could take this apart easily but I want it intact as well.



The back is not helpful at all. Pity it wasn't labeled or I wouldn't have this issue.

Thanks,

Your pictures are way too blurry to give you any
ideas or help...:cryyy:

This reminds me my Crown's 500mW module...the thing is that mine
had a cable coming out of the holes...:thinking:

This is slightly larger.



I should ask what area do would you need to see pictures of to get an idea? The one thing I'm fairly certain of is that alignment is fine. The person who put this together used so much epoxy.

I believe it is a 500mW module from o-like around 3 years old. The holes I see in the back are drilled, so I don't think there was wiring from the manufacturer just whatever the builder was doing.

I'd like to sell this off actually. What's the recommendation here? I'm worried about messing it up, and leaving myself with a few hundred dollar paperweight. It can't that hard to get to the contacts and test the module with a power supply though? I'm just afraid of removing the epoxy.

Thank you,

*facepalm

A large blurry image is no more helpful than a medium blurry image.
We can't see what is in the photos, and that defeats the purpose of a photo.

I appreciate your thorough explanation of why the photos are useless. When I have $500 to blow on a camera capable of micro-imaging perhaps I can correct that problem.

At this point I'll need to dig up whatever documentation exists on module dis-assembly. I'd appreciate any tips that aren't stating something obvious.

"A poor carpenter blames his tools."

Even if your camera was bad enough to not have any focus adjustment at all, you can hold a lens in front of it or simply move the subject further away until it is in focus. Even $500 cameras will take blurry pictures if you don't know what you're doing.

From the blurry picture I see a IR filter so I assume it is a green DPSS laser with a IR diodepump. All 808nm diodes are case positive. You must find the diode pin in the assembly. Hook it up on negative pole.
So you have now both poles and use the power supply to test it.

I bought the camera used years ago. I don't have a manual for and I don't know how to prevent the auto-focus that ruins the pictures.

Regardless, yes its a green DPSS. The problem with disassembly is the epoxy used all over the assembly. Also the 4 screws are put in at a horrible angle. Since they aren't straight this is difficult.

I will take a look at the camera, maybe the blurriness can be dealt with. This camera has always been a problem with the lack of autofocus. 12 megapixels.

I've had that camera about 4 years, never knew it had a macro button... I learned something so thanks. :beer:

Much better pictures this time:





Also a gallery of more if these aren't enough: higher resolution (not blurry) gallery

As you see from the pictures the way the screws are recessed so it makes hard to get them out. Next is that epoxy, I'm correct in that it needs to be removed? I'd appreciate any tips/advice/help once again.
Thanks
