Thread: ML520G72 638nm 500mw Diode Group Buy list

  1. #1

    Default ML520G72 638nm 500mw Diode Group Buy list

    “The Mitsubishi ML520G72 is a high-power, highly efficient semiconductor laser diode which provides an emission wavelength of 638 nm (bright red) and standard light output of 500mW.”

    This diode has several benefits over the traditional diodes used in laser projectors, one is the anode and cathode are isolated from the body which means you no longer need to insulate your diodes from the metal diode mount, also we have found the diode can handle over heating quite well and it will shut down when over heated then recover again when cooled for over 15minutes. The beam specs we have managed so far have been similar to the 445nm blue diodes albeit a little wider when used with a typical Open can collimator. Also we think the 500mW maximum can be exceeded too, however, as we do not have many to test yet we are not pushing them too much. I will upload some of our test photos soon as possible.

    The data sheet can be found here :

    This thread is to get a list ready for the order so we can see what kind of numbers are needed, we are close to the next break point of 200 so the price will drop once I confirm the quantity with Mitsu and everyone will benefit:

    Please keep questions on the other page http://www.photonlexicon.com/forums/...t=11609&page=2 so we can keep this one only related to numbers.


    Prices for ML520G72 Based upon current requirement of 100+

    210 USD each including shipping.
    164 Euro each
    including shipping.

    Shipping, will be standard flat rate, registered & tracking.

    The diodes come in an original Mitsubishi packet that has actual test data specific for the enclosed diode: its serial number, optical specs, threshold etc.., like a small personalized data sheet specific for the diode, these little packets will be placed in another protective packet or box as required.

    Delivery 2-3 weeks once the GB has closed.

    Getting close now to 200 units so we'll keep the GB open until we top it, then I will request another price from Mitsu and close the GB.

    Payment: Paypal. Details will be sent by PM along with the final total.

    Send me a PM with your "PL ID, Country, Quantity" so I can keep track easier on my local PC instead of having to copy the text too and from windows or maybe you will be missed of the list.

    If you want to be anonymous, just stick an 'A' at the end of the line like this:

    Total Diodes 220



    Optics

    I am going to offer 2 options for beam correction.

    1, knife edging lens set. 4mm x 0.5 - 1mm beam
    2, PBS combining set. 3mm x 2.5 mm beam


    Getting quite good results also with:
    http://www.photonlexicon.com/forums/...-prisms-are-go

    All info will follow soon, bare in mind I do not have much time to work on experimenting so be patient.

    Thats a super price! that half the price you would pay for 3 x 150mW 640nm, and you need only one collimator instead of 3. just add a 30 euro prism and you have a tight 500mW beam


    I'll take 6 pcs please!!!

    4 for me please.
    I want to see those new optics first - but I can wait, as I know your busy

    Better get a price break on 100, we're over halfway there now

    Cheers,
    Dan

    Why, building a a red with this diode is half the price then when you would build it with 150mW 640nm diodes.

    Signed up for 3 ...maybe more if I can scrape up the funds in time.
    Thanks for putting this together !!!! I am sure your optics will be a great addition. Can't wait to see these in action.
    You are the only one that can make your dreams come true....and the only one that can stop them...A.M. Dietrich
