I bought a custom laser here from a member here in a group buy. It is a blue 1w laser with a customisable focus that changes the laser from a straight beam to a widened point like a rectangle flashlight.
I accidentally turned the focus passed the furthest wide setting. Ever since the beam is very dim. It's brighter initially ( no brighter then my cell phone flash light ) then within a second gets less bright. I believe i messed up the focal allingment but idk. How do i go about fixing this? Or is there someone on the fourms who does repairs.

I have accidentally destroyed an M140 in a similar manner. The diode is LED'd due to the back reflection. This unfortunately isn't a case of focal alignment issues. The only way to fix it will be to swap out the diode for a new one.

This could have any of the diodes that came in Ca$io projectors, M140 or A140 or A130. None of these diodes are expensive any longer. I used to buy the M140s brand new from Techhood, but still never got the Nichi@ part number for them. About fours years ago I could get them new for $40.00 each if I purchased five, but you can now find harvested ones for $17.00 or less. If it has the less powerful A series diode, it can be replace with either one. I have both in my stock with no plans for either of them. If you can provide photos or a link to which laser this is, that would be helpful.

Hi,
Thats a 501B host and they can be repaired easily. I have made many in other colors. If you need it repaired let me know.

That's a Sci Fi unit also when they used to mark them.
May I ask how long ago you bought it and who was all involved, just curious?
I also think sending it to Lifetime17 is your best best as he's repaired many of these Sci Fi units..
If you need any reassurence with Lifetime as a member to work on it i'm sure everyone on the forum will vouch for him plus there are quite a few threads with his work on them.
He has the best means to make the repair as cheap as possible:)

Yes, this is a typical 501B host and very easy to work on. These were cheap hosts even back in the day when you purchased this laser. It still may need a diode, though. Rich is qualified to work on these as are many other members here. Good luck to you.
