    Default 10 diode 445 build

    bit of a rush job but built this for a customer.

    Nice! What lenses did you go with for that Andy? Do you have the divergence specs?

    I gotta know how you are getting a 1mm beam from a olike lens Do you just waste the rest of the power or run the diodes at a lower current? Inquiring minds want to know

    What current are you running the diodes at? Series / Parallel?
    Nice milling
    - There is no such word as "can't" -
    - 60% of the time it works every time -

    were you able to put a power meter on it? I am curious what the throughput was after the mirrors waveplate etc.
