    Happy days.

    A little bit of teamwork, logical thinking and a positive attitude nails most problems

    I found one of my greens was also very temperature sensitive to the cold. By holding my fingers over the fan intake for a period I managed to get it from ~200mW up to ~300mW, so in normal running mode it was obviously not at optimum. I guess you can have TOO much cooling.

    ...I've just received the "repaired" >450nm 532nm laser back from CNI and it's doing at least 550mW within the first 5 minutes, within a low ambient temperature room (brrrr, it's cold in Melbourne right now)!

    Although this unit has the same serial number as the last, I don't recognise it as being the same unit. There were a few mounting scratches, a different DB-9 plug housing etc. Where as this one looked brand new.

    So a good outcome (apart from the shipping of the faulty unit back to CNI which cost over AUD100).

    So again it's great to be able to rely on the LaserBee I for a decent indication that things are as they should be. And on that note, I've been using it quite extensively with my 445nm and 660nm diode experiments, seeing mW readings consistent with those expected for the supplied diode current.

    Glad to hear you got it all worked out.
    It's always good to here that a user is happy with and
    trusts his LaserBee readings... Thanks..
