Would matt black stove paint paint work? High temperature too.

An effective surface might be a series of baffles with extra absorbing surfaces or just cover a heat sink with matt black paint.

Hi Galvonaut:) good idea.
I just had a look at that link and went searching for similar stuff in Oz. looks pretty good. I cant find much about what is in it or what it's light absorbing properties are (not too surprising I guess)
I think I might have found who has the black velvet super absorbent material. http://www.acktar.com/category/BlackOpticalCoating There A4 sample packs are $129. Would be interesting to play with.
Here it is at Edmunds http://www.edmundoptics.com/lab-prod...bent-foil/3634
Yikes expensive:eek: bugger!
here are some other materials

The insides of cameras sometimes use a moleskin type material to stop specular reflections. It is cheap as anything, so worth experimenting with. This is cheap from an AV production supplier >> http://www.trewaudio.com/store/Mole-Skin.html
I did a search on moleskin+ flock+ camera and got this thread about applying similar stuff to telescopes.
