    Default 9mm 445 amazing

    After hitting my PS limits with TEC cooling, I decided to give this a go with no TEC, with the TEC I was able to get near 3.4W at 8C.

    My goal here was to find stability at ambient temperature for continuous duty as this will end up on a beam rail, and perhaps another scanner hey the rail has holes in each end. lol

    For my needs I feel I won;t need to TEC cool this as one I don;t like the weight of the linear supply for the TEC and another damn it heats the baseplate.

    I found that setting the current for an output after correction lens of 2.65W, that as the diode warmed over the first 5 minutes power dropped to 2.52W it then stayed stable at this power for over 2 hours. Could I push it harder, you bet it still makes more power when giving more current, but i'll be happy st 2.5W corrected it is a nice beam. This is more power than my dual m-140 after all optics. Hmm maybe time to swap it out, nah i'll just add scanner to this next build.

    wow, 2.5W of 445 out of one corrected diode

    I don't think I could have even imagined that a couple years ago

    Great work. Glad to see these are working out so well.

    At what current is this thing running? Somewhere like 2 amps?

    Sounds like these guys are terribly efficient. Cranking out 2,5W stable without even a fan, just an aluminum block.... what?

    Nice!!! Need to build a 5 watt with these then Would fit nicely in my new green/blue projectors


    Interested in a system or modules? Feel free to contact us directly!

    Parts & vendor list, please!

    One of these would be perfect for a single-color beam projector I'm itching to put together, and the less parts required, the better!

    I think I could make do with a single-diode at 2 watts + ...

    Diode from DTR
    Copper Barrel DTR
    405-G2 Lens DTR
    AIXIZ type mount Laserman532
    Driver P3
    Correction Dr Lava Cylinders
    Lens Mounts custom Machined (not sure of availability as there a big loss time : price ratio)

    you could just as easy use Dave's mount, but i like the centering (left right adjust hole spacing) on Pat's mounts and also the machined hole that you can mount a TEC into.
