    Default New C-mount for cheap green?

    I have an old noname 80-100mW 532nm module with a suspected faulty IR diode, it only outputs about 20mW when fed with 450mA!
    It used to give out 90mW but a spike from a bad driver might havedamaged it I think.
    The diode is a C-mount and it is surprisingly easy to get into the module, cheapies are usually glued shut but this one is different.
    What power do you think the diode is (was), 500mW?
    Is there any cheap sources for this kind o diode, snoctony on ebay wants 60USD, propably more than the entire module is worth when working!
    I want to try to align and get the module working as a learning experience... but not for 60 bucks!

    Try Aixiz lasers...may have a diode on the cheap....best to to just pick up another. 532nm is cheap now.

    Try e-mailing some of the manufacturers in china. They will have cheap pump diodes but you're still probably looking at $30 at the very cheapest for a 1W 808nm c-mount, and probably the same for a 500mW.

    The problem here is that shipping will likely be expensive...

    he usually has 1w cmount 808nm, a little more expensive than the ones from china but they are guaranteed good and he very reputable

    I got a beautiful C mount from junktronix, easy to deal with. Yeah, a bit more expensive then china, but he has them to like 5 watts.

    And I usually cut PL members a better than average deal

    I'd guess the diode was 1/2W since a 1.2W diode is barely at threshold at 450mA. I'm not sure if I have any 1/2W c-mounts, but I'll check if you're still looking for something.

    Sorry Kevin...I too soon forgot that you are a great source for parts. Kevin has the good diodes.....he tests each one and sees that you get actually more than a good deal !

    yup, i revived my original 50mw (first dpss laser) with one of his diodes. worked wonderfully.
