    Cool and simple !
    I assume TEC goes under diode mount, ( but that driver ?, no thermistor hole ? )

    Is that a 9mm, 50 thread in the holes or are the optics going in with some kind of sleeved holder ?

    Cheers

    I too am of the opinion that TEC cooling is not necessary with these diodes when mounted in a suitable heatsink such as this. Keeps the whole thing a lot simpler...

    My current experiments with a similar sized block of ali does not even require the fan I first fitted.

    AC,

    Yea....I do NOT think A TEC is needed !!! MAX stabillity of PO or NM oututput is not that critical for projector application !!!...See : Copper is Proper Blah, Blah !!

    Prisms or Cylindrical corrective optics ????? Set up looks very GOOD !!! Terra watt sez bow WOW !
