    Andy...DTR has'em for 110 USD.....I was just wondering if we have any " Early Adaptors " which have " Blazed a Trail " yet ???? Or....has Mitsui buggered it up ??? More bond wires good...a MUCH larger emitter !!! NOT good !! Things are toooo quite !!! Tension is building !!! See pic of the P73-2 Phog Horn !!! HAHA....BEAM

    Beam Axiom #6 ~ "A Posse ad Essea" ~ From being possible to being actual ...is the beam target !

    I wonder why andy and dtr are keeping
    Quiet on just how bad they are ?
    Surely cant be any worse than a regular
    C mount 635nm
    When God said “Let there be light” he surely must have meant perfectly coherent light.

    Default ML501P73-2 Spec Sheet...and more BEAM HUMOR !!

    See attached spec sheet of the P73-2...Is this what you are looking for ??? Via the fine work of Andy F and Mr.Briggs....the emitter has ..."been weighed, been measured, and has been found wanting" haha See GRIN Pic !!! BEAM

    Default A little more BEAM humor !!

    Andy...I could ignore you....but never your fine work here on PL.....BUT....I must follow with a little " BEAM" humor !!!!!

    I have stated that they do produce a few hundred more mW @ higher currents than the 300mW versions but they are much more stable where the 300mW drops like a stone over 800mA these stay pretty steady 1A+. I don't have any correction optics and I was hoping someone could shed some light on whether some of the techniques that have been used with the 300mW version will work well with these but I have not gotten any good feedback other than the 500's do have a slightly larger emitter. So I have not been keeping quite. I shared the little info I had.
