    From my calculations, 520mW of 635nm is worth 1500mW or 660nm. Now you have my interest! I have a spare B&K housing that could be purposed as per your culinary master piece.

    Thanks for the meal.

    Default 635

    hey doc
    was that 635 fac'ed or not ??
    what's the beam size ??
    When God said “Let there be light” he surely must have meant perfectly coherent light.

    The diode was the 100um including FAC lens, beam at aperture is 6x2

    Note that the beam shot was taken at half modulation as I like my testicles where they are (burned door frame incident in the summer ).

    Doc ---
    I presume you have a TEC sizzleing in that stew pot. How many watts are you feeding the TEC if there is one there?
    Nice optics job
