    I have 4 of the eightonlight, RGB projectors, but all with 445 blue...
    fwiw, they have all been solid construction, and if you need a variance, their is already a co. here in the U.S. , that imports and variances them for legal use.
    highly recommended projectors!
    although I have to admit, the 637nm red, that I ordered as 2 watt, are now doing 1.5 watts, after half year, but they are still maintiaining internal alignment..
    the greens are CNI and over spec,
    the blue modules are also good, ive only had 1 diode failure in 1 of them...
    PM me if you need the contact for US variance eightonlight projectors...

    You have had a diode failure after 6 months??? UNACCEPTABLE!!!

    True, but at the price point, I don't mind,
    I can swap out a diode , no big deal, and , 1 diode did fail, but the other one still works, so its not a show stopper ....still getting 1.6 watt out of the blue module..
    I can swap out as time allows.
    but overall, the projectors have been pretty solid....

Printing, mold making or contracting for a shaped lens might be tough.
    so we are actually contemplating "making our own" optical elements!
    all I can say is wow! That is taking the game to a whole new level...

    Maybe it is time for someone with access to an optics lab and ZEMAX software to step in?
    And then a manufacturer with some leverage in terms of production volumes?


    What we are discussing, in small numbers, will make attaching GRIN lenses to each diode look very very .. cheap!

    Did you ever try to attach a grin lens to a canned diode? It wont work due to the very short WD. YouŽll need to decan the diodes and glue the lens almost to the chip. Tough, timely and costly job. BTW, the grin lenses are not really cheap. Not sure how attractive it will be ($$lens + time). Sure the result may be great but what will the end price be?

    That is exactly what i am saying. It is a tough and expensive procedure as far as we know
    But making custom lenses that match the interference pattern of a diode in small scale will be even more expensive

    that's why we need a kind optics manufacturer by our side

    I bet each diode will be different from another even in the same batch so this might have to be done on a case by case basis making it really hard to do

    Attaching micro lenses to decanned diodes .. this seems familiar .. perhaps deja vu from the "grail" times .. ?

    I received my diode. I will try to get some testing and observations up tonight.
