Heatsinking a 5.6 can

Hey you-all:)
Which surfaces of a 5.6mm diode need to be in contact with the h.s. grease and aluminum housing? A, B, C, or all of the above?
Thanks,
Steve

Surfaces A and B are the accepted standard....easiest to machine for. I would allow some .002/.004" for thermal expansion. With an interference fit you may crack the window in front of the diode....BTDT. Oh by the wayI manged to kill the 635nm diode. I guess I spiked it ....misshandling. It did make 158mW of 635 though. Divergence...well....floodlight. I did install a FAC lens....a lot better , but no beam of use in a projector.

Oh geez .. ouch.. eh . i klled a 635 too. . felt kinda sick to my stomach :\
for a day or so... eh..
Well I dissected one of my dead Maxys this afternoon and put a 636 diode in it just for kix (just happened to be a 5.6 can that Chuck uses)_
Cant get the lens close enough (the thread run-off isnt quite deep enough) - looks like a fun project tho.. will post pics soon ..
Sorry for your loss Mike.. ohhh...
Thanx for the info tho.. that's what I was wondering..
Have a good one..

I fixed the problem...
Heres a 636 nm Maxy :D
'course it'll take an anamorphic przm or 2...

How big is that beam there man? Is it good enough for a projector?

5mm x 1mm at the ap, 34mm x 4mm rectangle at 14 ft. /fast axis tamed to to 8.5mm with an anamorphic prizm pair out of one of Laser Ben's MG modules at the output lens. Not stellar, but a fun project :).
I guess I need a slightly higher power prizm pair (if they make 'em)..
