Heya!
I have some of those RGB all in one 500mw modules I got surplus. The reds are blown. I've been lazy, but as a weekend project decided to replace one of the reds. Have LPC-840.
The module has a block screwed to baseplate with a round diode holder in it secured with two set screws.
The diode holder has the laser diode in it, a lens on the front and the diode is held in by a brass round thing that has the straight screw thing. So it was put together with a special tool.
In trying to remove said screwed in ring that holds the diode down, I kinda trashed them. Soft brass, and it might have threadlock compound. One still has some hope but I have to make my own tool to remove these, nothing I have works. Security bit came close.
The round thing is 14mm on the outside, and about 20mm or so deep.
When I google diode mounts and checked my box of random laser parts, they are all 12mm
Anyone know a source for these stupid 12mm x 20mm things and the brass rings that go inside to hold the diode down?
I will post picture when I get home.
They're not worth that much it was more of a "Hope this won't take more than half an hour" .... yea....
