Dear Joseph kindly go through the above links, it may be helpful to you for your project.

Have a nice day.

Joseph,

Exactly what are you hoping to absorb? Gas? Light/heat?

I sense, and I could be wrong, that you're trying to measure the combined effective of emissivity and albedo of a material - which 'can' be termed the absorptivity.

Any hints would be useful.
